It discusses using ternary (1, 0, 1) instead of binary to represent numbers, allowing for higher information storage capacity. The authors propose implementing an all-optical ternary half adder circuit using wavelength conversion via nonlinear polarization rotation in semiconductor optical amplifiers. This scheme aims to overcome limitations of prior work such as intensity loss and requirements for precise beam control.
The document summarizes an investigation that measured the optical band gaps of 23 ternary and quaternary sulfide minerals using diffuse reflectance spectroscopy. The band gaps measured for the ternary and quaternary sulfides tended to lie between the band gaps of the binary sulfide components. Comparison of band gaps determined by diffuse reflectance and single-crystal methods for 12 binary sulfides showed diffuse reflectance produced accurate results within 0.1 eV. Unlike binary sulfides, the band gaps of ternary and quaternary sulfides clustered within ranges determined by chemical composition rather than correlating linearly with bond energy measures.

Elliptic Fourier Descriptors in the Study of Cyclone Cloud Intensity PatternsCSCJournals
Cyclone cloud intensity analysis is conducted to study the evolution of a cyclone storm mainly using two approaches, namely: wind field analysis and pattern recognition. Of the pattern recognition based approaches , the Dvorak technique has been a pioneering effort which is widely used today. However, the Dvorak technique is subjective, as it relies on human judgment and is, therefore, error prone. Efforts have been described in the literature to automate the classification process. In this paper, we describe our efforts to perform a semi-automatic computer analysis of the cyclone cloud intensity evolution pattern which compares preprocessed visible (VIS) and enhanced infra-red (EIR) satellite images with the corresponding prototype Dvorak patterns using Elliptic Fourier Descriptors (EFD) and Principal Component Analysis (PCA) techniques. This novel approach is simple and intuitive and is robust to noise, and at the same time provides classification in cases where the cyclone exhibits fluctuations during its evolutionary cycle.
This document outlines techniques for anti-phishing including visual cryptography and halftoning. It discusses the history of anti-phishing becoming more widely adopted in the late 2000s.

Mobile phone cloning involves illegally reprogramming the identifying information from one phone into another. This allows calls made on the cloned phone to be billed to the legitimate subscriber. While mobile cloning has been an issue since the 1990s in other markets, it is an emerging threat in India. Cloning can be done by using software to modify the phone's ESN or MIN and programs these identifiers into another phone. Service providers find it difficult to detect cloning right away due to monthly billing cycles.

It also offers apps like Find My iPhone to locate lost devices, Photo Stream to share photos, and iCloud Keychain to store passwords and credit cards. iCloud provides 5GB of free storage that can be upgraded for a fee. It aims to provide a seamless experience across Apple devices by keeping content and data up to date on all devices.
This document provides an overview of the iOS architecture and file system. It discusses that iOS was originally developed for the iPhone but can support other Apple devices. The file system handles persistent storage and is based on the Unix file system. The iOS architecture has four main layers - the Core OS layer, Core Services layer, Media layer, and Cocoa Touch layer. Each layer provides different fundamental services with the Core OS layer being the lowest level. The document also explains that each iOS app is isolated to its own sandbox directory and has limited access to files outside of this directory.
iOS is Apple's mobile operating system that runs on the iPhone, iPad, and iPod touch. It uses a graphical user interface designed for touchscreen input. While providing a basic interface, each new version of iOS adds more features such as support for third-party apps, copy/paste functionality, and Siri. iOS powers portable devices through frameworks for building apps, multimedia, and low-level system functions. It provides technologies for graphics, audio/video, text handling, imaging, and accessing a user's media through layers of abstraction.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

1. CHAPTER 1
ABOUT ICLOUD
iCloud is a cloud storage and cloud computing service from Apple Inc. launched on October 12,
2011. As of July 2013, the service has 320 million users.
The service allows users to store data such as music and iOS applications on remote computer
servers for download to multiple devices such as iOS-based devices running iOS 5 or later, and
personal computers running OS X 10.7.2 "Lion" or later, or Microsoft Windows (Windows
Vistaservice pack 2 or later). It also replaces Apple's MobileMe service, acting as a data syncing
center for email, contacts, calendars, bookmarks, notes, reminders (to-do lists), iWork
documents, photos and other data. The service also allows users to wirelessly back up their iOS
devices to iCloud instead of manually doing so using iTunes. iCloud data center is located in
Maiden, North Carolina.

1.1 ANNOUNCEMENT
The first official mention of iCloud from Apple came on May 31, 2011, when a press
release announced that it would demonstrate the service at the WWDC on June 6, 2011. A
banner hung at the Moscone Center for WWDC revealed the iCloud logo five days before the
official launch.
In the WWDC 2011 keynote speech, Apple announced iCloud will replace MobileMe services
and that the basic iCloud service will be free of charge.
1.2 Apple ID
You need an Apple ID to sign up for iCloud. You may already have an Apple ID if you've
purchased or downloaded content from iTunes Store, App Store, and iBookstore, or signed in to
Game Center or FaceTime.
1.3 USE ICLOUD.COM
You can access your iCloud information using a computer web browser instead of using apps on
your iOS device, Mac, or Windows computer. You go to iCloud.com, sign in, and then use the
iCloud.com web apps: Mail, Contacts, Calendar, Notes, Reminders, Find My iPhone, Pages,
Numbers, and Keynote.
To prevent anyone from accessing your iCloud information on iCloud.com (such as your email)
while you’re away from your computer, you can sign out. If you’re now signed in from more
than one browser, you can sign out from all browsers at once.

3. CHAPTER 2
HISTORY
iCloud is the latest branding of Apple's cloud computing services. It has previously been branded
as iTools in 2000, .Mac in 2002, and MobileMe in 2008.
iCloud was announced on June 6, 2011, at the 2011 Apple Worldwide Developers
Conference (WWDC). Apple announced that MobileMe would be discontinued after June 30,
2012, with anyone who had an account before the unveiling of iCloud having their MobileMe
service extended to that date, free of charge.
The official website, www.icloud.com, went live in early August for Apple Developers. On
October 12, 2011, iCloud became available to use via an iTunes update. iCloud had 20 million
users in less than a week after launch. The iCloud.com domain and registered trademark were
bought
from
a
Swedish
company
called
Xcerion,
who
rebranded
their
service
to CloudMe. CloudMe still controls major domains like iCloud.de, iCloud.fr and iCloud.es.
A class action lawsuit by customers unhappy over the transition from MobileMe to iCloud was
filed in early May 2012.

4. CHAPTER 3
ICLOUD FUNDAMENTALS
3.1 ICLOUD FUNDAMENTALS
From a user’s perspective, iCloud is a simple feature that automatically makes their personal
content available on all their devices. To make your app participate in this ―magic,‖ you need to
design and implement your app somewhat differently, and for this you need to learn about your
app’s roles when it participates with iCloud.
These roles, and the specifics of your iCloud adoption process, depend on your app. You design
how your app manages its data, so only you can decide which iCloud supporting technologies
your app needs and which ones it does not.
This chapter gets you started with the fundamental elements of iCloud that all developers need to
know.
3.2 FIRST, PROVISION YOUR DEVELOPMENT DEVICES
To start developing an iCloud app, you must have an appropriate device provisioning profile and
app ID. If you don’t already have these in place, learn about setting up a provisioning profile and
app ID in ―Provisioning Your App for Store Technologies‖ in App Distribution Guide.
3.3 ICLOUD DATA TRANSFER PROCEEDS AUTOMATICALLY AND
SECURELY
When you adopt iCloud, the operating system initiates and manages uploading and downloading
of data for the devices attached to an iCloud account. Your app does not directly communicate
with iCloud servers and, in most cases, does not invoke upload or download of data. At a very
high level, the process works as follows:
4
5. 1.
You configure your app to gain access to special local file system locations known as
ubiquity containers.
2.
You design your app to respond appropriately to changes in the availability of iCloud (such
as if a user signs out of iCloud), and to changes in the locations of files (because instances of
your app on other devices can rename, move, duplicate, or delete files).
3.
Your app reads and writes to its ubiquity containers using APIs that provide file
coordination.
4.
The operating system automatically transfers data to and from iCloud as needed.
In iOS, there is an exception to automatic iCloud data transfer. For the first-time download of an
iCloud-based document in iOS, your app actively requests the document.
iCloud secures user data with encryption in transit and on the iCloud servers, and by using secure
tokens for authentication. Key-value storage employs the same security as iCloud uses for
"Documents in the Cloud,‖ as it is described in that document.
3.4
THE
UBIQUITY
CONTAINER,
ICLOUD
STORAGE,
AND
ENTITLEMENTS
To save data to iCloud, your app places the data in special file system locations known as
ubiquity containers. A ubiquity container serves as the local representation of corresponding
iCloud storage. It is outside of your app’s sandbox container, as shown in Figure 3.1.
5
6. Figure 3.1
Your app’s main ubiquity container in context
To enable your app to access ubiquity containers, you request the appropriate iCloud
entitlements.
3.5 A USER’S ICLOUD STORAGE IS LIMITED
Each iCloud user receives an allotment of complimentary storage space and can purchase more
as needed. Because this space is shared by a user’s iCloud-enabled iOS and Mac apps, a user
with many apps can run out of space. For this reason, to be a good iCloud citizen, it’s important
that your app saves to iCloud only what is needed in iCloud. Specifically:
●
DO store the following in iCloud:
●
User documents
6
7. ●
App-specific files containing user-created data
●
Preferences and app state (using key-value storage, which does not count against a user’s
iCloud storage allotment)
●
Change log files for a SQLite database (a SQLite database’s store file must never be
stored in iCloud)
●
DO NOT store the following in iCloud:
●
Cache files
●
Temporary files
●
App support files that your app creates and can recreate
●
Large downloaded data file
3.6 THE SYSTEM MANAGES LOCAL ICLOUD STORAGE
A user’s iCloud data lives on Apple’s iCloud servers, and a cache lives locally on each of the
user’s devices, as shown in Figure 3.2.
Local caching of iCloud data allows a user to continue working even when the network is
unavailable, such as when they turn on Airplane mode.
7
8. Figure 3.2
iCloud files are cached on local devices and stored in iCloud
Because the local cache of iCloud data shares space with the other files on a device, in some
cases there is not sufficient local storage available for all of a user’s iCloud data. The system
addresses this issue, automatically, by maintaining an optimized subset of files locally. At the
same time, the system keeps all metadata local, thereby ensuring that your app’s users can access
all their files, local or not. For example, the system might
evict
a
file
from
its
ubiquity
container if that file is not being used and local space is needed for another file that the user
wants now; but updated metadata for the evicted file remains local.The user can still see the
name and other information for the evicted file, and, if connected to the network, can open it.

9. CHAPTER 4
FEATURES
The cloud-based system allows users to store music, photos, applications, documents,
bookmarks, reminders, backups, notes, iBooks, and contacts, and provides a platform for Apple's
email servers and calendars. Third-party iOS and OS X app developers are able to implement
iCloud functionality in their apps through the iCloud API.
4.1 BACKUP AND RESTORE
iCloud allows users to back up the settings and data on iOS devices running iOS 5 or later. Data
backed up includes photos and videos in the Camera Roll, device settings, app data, messages
(iMessage, SMS, and MMS), ringtones, and Visual Voicemails. Backups occur daily when the
device is locked and connected to Wi-Fi and a power source. In case of a malfunction of any
Apple device, during the restoration process, iCloud offers to restore all data along with App
data only if the device was synced to iCloud and backed up.
4.2 BACK TO MY MAC
Back to My Mac, also previously part of MobileMe, is now part of iCloud. As before, this
service allows users to log in remotely to other computers that have Back to My Mac enabled
and are configured with the same Apple ID.
4.3 EMAIL, CONTACTS, AND CALENDARS
As with MobileMe (and .Mac and iTools before it), an iCloud account includes an email account.
Unlike MobileMe and its previous iterations, an email address is an optional part of an iCloud
account, in that the user can choose not to use it but can still use the email as their iCloud Apple
ID. The email account can be accessed using any standard IMAP-compatible email client as well
as the web portal mail client on iCloud.com. Additionally, on an iOS device, iCloud email is
push-enabled.
Users converting existing MobileMe accounts to iCloud accounts kept their existing "@me.com"
email addresses, and users whose accounts pre-dated MobileMe and had both me.com and
mac.com email addresses kept both. In iOS 6 beta 3, Apple gave notice to developers that new
10. signups would instead get "@icloud.com" email addresses. As with the .Mac to MobileMe
transition, existing users get to keep their old addresses and also get a matching new icloud.com
address, so messages sent to a valid account with multiple addresses all end up in the same
inbox.
Users setting up new iCloud accounts, whether completely new or attaching them to existing
non-MobileMe Apple IDs, can opt to not have email with their iCloud account. These users don't
see the iCloud webmail component when signing in at iCloud.com. They still need a valid email
address with another email provider to sign-up (e.g. a Gmail account), and that existing nonApple email address becomes their iCloud login.
4.4 FIND MY FRIENDS
In iOS 5, iCloud introduced a new feature called Find My Friends. Find My Friends is very
similar to Find My iPhone, except users can share their location with other friends or family
using the feature. Concurrently with the launch of iOS 5, Apple released an app for Find My
Friends. iOS 6 added location-based alerts to notify the user when a device arrives at a certain
location.
4.5 FIND MY IPHONE
Find My iPhone, formerly part of MobileMe, allows users to track the location of their iOS
device or Mac. A user can see the device's approximate location on a map (along with a circle
showing the radius depicting the margin of error), display a message and/or play a sound on the
device (even if it is set to silent), change the password on the device, and remotely erase its
contents. The feature was first announced on June 10, 2009 and was included in iOS 3.0 software
update as a feature for paying MobileMe users. Find My iPhone was made free of charge with
the iOS 4.2.1 software update on November 22, 2010, but only for devices introduced in 2010.
An iOS app was also released by Apple on June 18, 2010, which allows users to locate their
device from other iOS devices running iOS 4 or later software. In iOS 5, Find My iPhone was
continued as a feature for iCloud. iOS 6 introduced Lost Mode, a new feature that allows the user
to mark a device as "lost", making it easier to protect and find. The feature also allows someone
that finds the user's lost iPhone to call the user directly without unlocking it. Similar phone
finder services under various names are available for other families of smartphones.
10
11. 4.6 ICLOUD KEYCHAIN
iCloud
Keychain was
announced
at
the
2013 Apple
Worldwide
Developers
Conference (WWDC), to be released as part of iOS 7 and OS X Mavericks (version 10.9). It was
not released with the initial release of iOS 7, instead being added with the release of iOS 7.0.3
and OS X Mavericks following Apple's October 22, 2013 event. It re-introduces the old
MobileMe Keychain syncing function that was removed with the initial release of iCloud in
2011, but now renamed iCloud Keychain.
It functions as a secure database that allows information including a user's website login
passwords, Wi-Fi network passwords, credit/debit card management (though without CVV), and
other account data, to be securely stored for quick access and auto-fill on webpages and
elsewhere when the user needs instant access to them. They are always stored encrypted using
256-bit AESencryption, are stored on device and pushed from iCloud between devices, and only
available on a user's trusted devices.
The service can also suggest new longer and more secure passwords to the user, if and when
required. It will only be available for use on Apple platforms, and even more specifically, when
using inside a browser, will only work with Safari browser on iOS 7.0.3 and OS X Mavericks
(version 10.9) onwards.
4.7 ITUNES MATCH
iTunes Match debuted on November 14, 2011. It was initially available to US users only. For an
annual fee, customers can scan and match tracks in their iTunes music library, including tracks
copied from CDs or other sources, with tracks in the iTunes Store, so customers do not have to
repurchase said tracks. Customers may download up to 25,000 tracks in 256 kbit/s DRMfree AAC file format that match tracks in any supported audio file formats in customers' iTunes
libraries, including ALAC and MP3. Customers also have the choice to keep their original copies
stored on their computers or have them replaced by copies from the iTunes Store. Any music not
available in the iTunes Store is uploaded for download onto customers' other supported devices
and computers; doing this will not take storage from the customers' iCloud's storage allowance.
Any
such
tracks
stored
in
the
higher
quality lossless
audio ALAC,
or
original
uncompressed PCMformats, WAV and AIFF, are transcoded to 256 kbit/s DRM-free AAC
11
12. format before uploading to the customers' iCloud storage account, leaving the original higher
quality local files in their original format.
If a user stops paying for the iTunes Match service, all copies of the DRM-free AAC iTunes
Store versions of tracks that have already been downloaded onto any device can be kept, whether
on iOS devices or computers.
From iOS 7 and OS X Mavericks onwards, the iTunes Radio function will be available across
devices, including integration with the Music app, both on portable iOS devices and Apple
TV (2nd generation onwards), as well as inside the iTunes app on Macintosh and Windows
computers. It will be included in an ad-free version for subscribers to the iTunes Match service
and will initially be available in the US only, before rolling-out to other countries later.
As of December 9, 2013, iTunes Match is available in 116 countries with the addition of Finland,
Denmark, Norway, and Sweden, while iTunes in the Cloud is available in 155 countries.
4.8 IWORK FOR ICLOUD
During the 2013 Apple Worldwide Developers Conference (WWDC) keynote speech, iWork for
iCloud was announced for release at the same time as the next version of the app versions of
iWork later in the year. The three apps for both iOS and OS X that form Apple's iWork suite
(Pages, Numbers, and Keynote), will be made available on a web interface (named as Pages for
iCloud, Numbers for iCloud, and Keynote for iCloud respectively), and accessed via the iCloud
website under each users iCloud Apple ID login. They will also sync with the users iOS and OS
X versions of the app, should they have them, again via their iCloud Apple ID.
This allows the user to edit and create documents on the web, using one of the supported
browsers; currently Safari, Chrome, and Internet Explorer. It also means that Microsoft
Windows users now have access to these native –previously only Apple device– document
editing tools, via the web interface.
4.9 PHOTO STREAM
Photo Stream is a service supplied with the basic iCloud service which allows users to store the
most recent 1,000 photos on the iCloud servers up to 30 days free of charge. When a photo is
taken on a device with Photo Stream enabled, it is automatically uploaded to the iCloud servers;
from there, it is automatically pushed to the rest of the user's registered devices. Photos in Photo
12
13. Stream will automatically be removed from other devices after the user reaches the 1,000 photo
or 30 day limit. Users who utilize Photo Stream on their Mac or PC can choose to have all photos
permanently saved on their computer - their photos in Photo Stream will not be removed from
the computer when they are dropped out of Photo Stream after the user reaches the 1,000 photo
or 30 day limit. The service is also integrated with Apple TV, allowing users to view their recent
photos wirelessly on their HDTV.
4.10 STORAGE
Since introduction in 2011, each account has 5 GB of free storage for owners of either an iOS
device using iOS 5.x or later, or a Mac using OS X Lion 10.7 or later. Additional storage can be
purchased in tiers of 10, 20, or 50 GB – 50 GB being the maximum. The amount of storage is
shared across all devices per iCloud Apple ID.
Several native features of iCloud use each user's iCloud storage allowance, specifically, Backup
and restore, and email, Contacts, and Calendars. On Macs, users can also store most filetypes
into iCloud folders of their choosing, rather than only storing them locally on the machine. While
Photo Stream uses the iCloud servers, usage does not come out of the user's iCloud storage
allowance. iTunes Match music content that is not sold in the iTunes Store also gets uploaded to
the user's iCloud storage and comes out of the user's allowance. Other apps can optionally
integrate app storage out of the user's iCloud storage allowance.
Not all of a user's content counts as part of their iCloud storage allowance. Apple is able to keep
a permanent track of every purchase a user makes under their Apple ID account, and by
associating each piece of content with the user, means only one copy of every Store item is
needed to be kept on Apple's servers. For items bought from the iTunes Store (music, music
videos, movies, TV shows), iBookStore (books), or App Store (iOS apps), this uses a service
Apple call iTunes in the Cloud, allowing the user to automatically, or manually if preferred, redownload any of their previous purchases on to a Mac, PC, or iOS device.Downloaded (or
streamed, provided the user is connected to the Internet) iTunes Store content can be used across
all these devices, however while iBookStore and App Store content can be downloaded to Macs
and PCs for syncing to iOS devices, only the iOS devices themselves can be used to read books
or use the iOS apps. Similarly, OS X apps purchased from the Mac App Store are also linked to
the Apple ID they were purchased through, and are able to be downloaded to any Mac using the
13
14. same Apple ID. Also, when a user registers any new device, all previously bought Store content
can be downloaded from the Store servers, or non-Store content from the iCloud servers.
In addition to the free 5 GB of iCloud storage, previous MobileMe accounts (to be precise, those
"individual" accounts, or the master account user only, not the sub-members, on "family pack"
accounts) were automatically given the extra 20 GB tier on iCloud, and those with MobileMe
accounts with 40 or 60 GB of additional purchased storage received a complimentary upgrade of
50 GB of iCloud storage. Originally this was going to be until the close of the MobileMe service
on June 30, 2012, but Apple later extended this to be until September 30, 2012. On September
30, 2012 users noticed that the free storage upgrade had not expired, but had seemingly been
extended 50 years longer, with their devices showing an expiry date of September 30,
2038.However over the course of the next few days this soon changed to show just a year's
extension, until September 30, 2013, with Apple emailing customers to advise them of the
extension. On August 1, 2013, Apple posted a knowledge base article and emailed affected
former MobileMe customers who received the free storage upgrade, to notify them that this
expires on September 30, 2013, and would then revert to the free 5 GB tier, also advising them in
the email of the amount of iCloud storage they were currently using. As expected, on September
30, 2013, Apple ended the complimentary storage plan upgrades for former MobileMe members,
re-advising them by emailing where they also told users the amount of iCloud data they were
currently left using.

PRIVACY AND SECURITY
Apple takes data security and privacy of your personal information very seriously. iCloud is built
with industry-standard security practices and employs strict policies to protect your data.
6.1 DATA SECURITY
iCloud secures your data by encrypting it when it is sent over the Internet, storing it in an
encrypted format when kept on server (review the table below for detail), and using secure
tokens for authentication. This means that your data is protected from unauthorized access both
while it is being transmitted to your devices and when it is stored in the cloud. iCloud uses a
minimum of 128-bit AES encryption—the same level of security employed by major financial
institutions—and never provides encryption keys to any third parties.
6.2 SECURITY AND ICLOUD FEATURES
The table below summarizes how your data is secured when using various iCloud features:

an uppercase letter, and a lowercase letter. Using a strong password is the most important thing
you can do to help keep your data secure. Learn more about creating a strong password.
6.3 PRIVACY
Apple has a company-wide commitment to your privacy. Our Privacy Policy covers how we
collect, use, disclose, transfer and store your information.
22
23. In addition to adhering to the Apple Privacy Policy, Apple designs iCloud features with your
privacy in mind. For example:
6.3.1 FIND MY IPHONE
You must turn on Find My iPhone, iPad, and iPod touch in iOS Settings before your device
can be located.
You must turn on Find My Mac in OS X System Preferences before your Mac can be
located.
Location data is sent from your device only when you request its location—it is not
transmitted or recorded at any other time.
Last known device location data is stored on Apple's servers in an encrypted format for 24
hours and then permanently deleted.
Lost Mode data is stored on the device that is in Lost Mode and retrieved on-demand by
you only.
You are automatically signed out of the Find My iPhone app (on device or on the web) after
15 minutes of inactivity.
Remote Lock allows you lock a device's screen to prevent others from accessing your data.
Remote Wipe lets you permanently and securely erase your data from a device.
6.3.2 FIND MY FRIENDS
To use Find My Friends, you must first download the optional and free Find My Friends
app from the App Store.
For someone to see your location, you must first give that person explicit permission.
Your location is sent from your device only when a friend requests to see your location—it
is not transmitted or recorded at any other time.
There is a single switch you can use to hide from all of your friends at any time.
Last known location data is stored on Apple's servers in an encrypted format for only 2
hours, and then permanently deleted.
If you do not have a passcode lock set on your device, you will be automatically signed out
of Find My Friends after 15 minutes of inactivity.
23
24. 6.3.3 ICLOUD KEYCHAIN
iCloud Keychain encryption keys are created on your devices, and Apple can't access those
keys. Only encrypted keychain data passes through Apple's servers, and Apple can't access
any of the key material that could be used to decrypt that data.
Only trusted devices that you approved can access your iCloud Keychain.
Advanced settings allow you to choose an iCloud Security Code longer than four digits or
have your device generate one for you.
You can choose to disable keychain recovery, which means that iCloud Keychain is kept up
to date across your approved devices, but the encrypted data is not stored with Apple and
cannot be recovered if all of your devices are lost.
6.3.4 PHOTOS
You can delete unwanted photos from My Photo Stream at any time. Learn about deleting
your photos.
You can delete unwanted photos and videos from your shared photo streams at any
time. Learn how to delete photos and videos from a shared photo stream.
You can remove subscribers from shared photo streams that you created at any time. Learn
how to move subscribers from your shared photo stream.

CHAPTER 8
ABOUT INCORPORATING ICLOUD INTO YOUR APP
iCloud is a free service that lets users access their personal content on all their devices—
wirelessly
and
automaticallyviaAppleID.iClouddoesthisbycombiningnetwork-
basedstoragewithdedicatedAPIs,supported by full integration with the operating system. Apple
provides server infrastructure, backup, and user accounts, so you can focus on building great
iCloud-enabled apps.
27
28. The core idea behind iCloud is to eliminate explicit synchronization between devices. A user
never needs to think about syncing and your app never interacts directly with iCloud servers.
When you adopt iCloud storage APIs as described in this document, changes appear
automatically on all the devices attached to an iCloud account. Your users get safe, consistent,
and transparent access to their personal content everywhere.
8.1 AT A GLANCE
iCloud is all about content, so your integration effort focuses on the model layer of your app.
Because instances of your app running on a user’s other devices can change the local app
instance’s data model, you design your app to handle such changes. You might also need to
modify the user interface for presenting iCloud-based files and information.
28
29. There is one important case for which Cocoa adopts iCloud for you. A document-based app for
OS X v10.8 or later requires very little iCloud adoption work, thanks to the capabilities of the
NSDocumentclass.
There are many different ways you can use iCloud storage, and a variety of technologies
available to access it. This document introduces all the iCloud storage APIs and offers guidance
in how to design your app in the context of iCloud.
8.2 ICLOUD SUPPORTS USER WORKFLOWS
Adopting iCloud in your app lets your users begin a workflow on one device and finish it on
another.
Say you provide a podcast app. A commuter subscribes to a podcast on his iPhone and listens to
the first twenty minutes on his way to work. At the office, he launches your app on his iPad. The
episode automatically downloads and the play head advances to the point he was listening to.
Or say you provide a drawing app for iOS and OS X. In the morning, an architect creates some
sketches on her iPad while visiting a client. On returning to her studio, she launches your app on
her iMac. All the new sketches are already there, waiting to be opened and worked on.
To store state information for the podcast app in iCloud, you’d use iCloud key-value storage. To
store the architectural drawings in iCloud, you’d use iCloud document storage.
29
30. 8.3 THREE KINDS OF ICLOUD STORAGE
iCloud supports three kinds of storage. To pick the right one (or combination) for your app, make
sure you understand the intent and capabilities of each. The three kinds of iCloud storage are:
●
Key-value storage for discrete values, such as preferences, settings, and simple app state.
●
Document storage for user-visible file-based information such as word processing
documents, drawings, and complex app state.
●
Core Data storage for shoebox-style apps and server-based, multi-device database solutions
for structured content. iCloud Core Data storage is built on document storage and employs the
same iCloud APIs.
30
32. CONCLUSIONS
iCloud gives you access to all your music, photos, and documents and more without you having
to think about file transfers via USB or a manual wireless sync. iCloud is a set of online services
that ultimately wants to eliminate the need of a central repository the digital hub from where
users were forced to start moving content onto other devices, like iPods and iPhone.
iCloud permeates every aspect of the operating system and it’s built into the apps you use every
day. If you create or edit bookmarks on Safari for Mac, changes will appear on Safari for iOS;
when you add a page to the new Reading List, that page will be instantly pushed to all your
devices’ Safari browser.
Cloud computing has enabled teams and organizations to streamline lengthy procurement
processes.
