4. General Overview
• iOS, which was previously called iPhone OS, is a mobile operating system
developed by Apple Inc. Its first release was in 2007, which included iPhone and
iPod Touch. iPad (1st Generation) was released in April 2010 and iPad Mini was
released in November 2012.
• The iOS devices get evolved quite frequently and from experience, we find that at
least one version of iPhone and iPad is launched every year. Now, we have
iphone5 launched which has its predecessors starting from iPhone, iPhone 3gs,
iPhone 4, iPhone 4s. Similarly, iPad has evolved from iPad (1st Generation) to
iPad (4th Generation) and an additional iPad Mini version.
• The iOS SDK has evolved from 1.0 to 6.0. iOS 6.0, the latest SDK is the only
officially supported version in Xcode 4.5 and higher. We have a rich Apple
documentation and we can find which methods and libraries can be used based
on our deployment target. In the current version of Xcode, we’ll be able to choose
between deployment targets of iOS 4.3, 5.0 and 6.0.

10. Similarities Between iOS and Android
•The basic functions in iOS and Android are alike. Both the iOS and Android
phones have calling, messaging, web browsing, video chat, maps, voice
commands etc.
•The user interfaces of iOS and Android have a lot of similarities. Both of these
support swiping, tapping, pinch and zoom etc on their phone screens.
•There is a status bar on both the iOS and Android devices and it offers similar
information such as battery life, time, app notifications, wifi etc.
•4G cellular network can be enjoyed on both the iOS and Android devices. This is
very important as cellular network is crucial for internet surfing.
•Privacy settings are paramount in both iOS and Android. Users are presented
with app permissions as this lessens the risk of data leakage.
Swapnali Pawar

11. Differences Between iOS and Android
•iOS is a closed system whereas Android is more open. Users have barely any
system permissions in iOS but in Android, users can customize their phones
easily.
•Android software is available for many manufacturers such as Samsung, LG etc.
and this may lead to some quality problems in the cheaper phones. However, iOS
is strictly controlled by Apple and there is no quality problem as there are few
models.
•The Android applications are obtained from Google Play while iOS applications
are available in the Apple app store.
•Integration with other devices is better in Apple iOS as compared to Google
Android.
•There are different voice assistants for iOS and Android namely Siri and Google
Assistant. Google assistant is much more powerful than Siri.
•The running speed of iOS devices remains consistent with time. In contrast to
this, the performance of Android devices may decline over time.

patches are available soonest to Pixel device
users. Manufacturers tend to lag behind in
pushing out these updates. So at any given
time a vast majority of Android devices are

rare, because iOS is locked and downloading
apps out of the App Store is complicated.

16. IOS LAYERED ARCHITECTURE
The iOS is the operating system created by Apple Inc. for mobile devices. The iOS is used in
many of the mobile devices for Apple such as iPhone, iPod, iPad etc. The iOS is used a lot
and only lags behind Android in terms of popularity.
The iOS architecture is layered. It contains an intermediate layer between the applications
and the hardware so they do not communicate directly. The lower layers in iOS provide the
basic services and the higher layers provide the user interface and sophisticated graphics.
Swapnali Pawar

17. IOS LAYERED ARCHITECTURE
Swapnali Pawar

18. What is the architecture of iOS ?
• Architecture of IOS is a layered architecture. At the uppermost level iOS works as
an intermediary between the underlying hardware and the apps you make. Apps
do not communicate to the underlying hardware directly.
• Apps talk with the hardware through a collection of well defined system
interfaces. These interfaces make it simple to write apps that work
constantly on devices having various hardware abilities.
• Lower layers gives the basic services which all application relies on and higher
level layer gives sophisticated graphics and interface related services.
Apple provides most of its system interfaces in special packages called
frameworks.
• A framework is a directory that holds a dynamic shared library that is .a
files, related resources like as header files, images, and helper apps
required to support that library. Every layer have a set of Framework which
the developer use to construct the applications.

19. 1.Core OS Layer
All the iOS technologies are build on the low level features
provided by the Core OS layer. These technologies include
Core Bluetooth Framework, External Accessory
Framework, Accelerate Framework, Security Services
Framework, Local Authorisation Framework etc.
Swapnali Pawar

20. 1. Core OS Layer
The Core OS layer holds the low level features that most other
technologies are built upon.
•Core Bluetooth Framework.
•Accelerate Framework.
•External Accessory Framework.
•Security Services framework.
•Local Authentication framework.
64-Bit support from IOS7 supports the 64 bit app development and
enables the application to run faster.

21. 2.CORE SERVICES Layer
Some important frameworks are present in the CORE
SERVICES Layer which helps the iOS operating system to cure
itself ad provide better functionality. It is the 2nd lowest layer
in the Architecture
Swapnali Pawar

22. 2.Core Services Layer
There are many frameworks available in the core services layer.
Cloudkit Framework
The data can be moved between the app the iCloud using the Cloudkit Framework.
Core Foundation Framework
This provides the data management and service features for the iOS apps.
Core Data Framework
The data model of the model view controller app is handled using the Core Data Framework.
Address Book Framework
The address book framework provides access to the contacts database of the user.
Core Motion Framework
All the motion based data on the device is accessed using core motion framework.
Healthkit Framework
The health related information of the user can be handled by this new framework.
Core Location Framework
This framework provides the location and heading information to the various apps.

23. 3.MEDIA Layer
With the help of the media layer, we will
enable all graphics video, and audio technology
of the system. This is the second layer in the
architecture
Swapnali Pawar

24. 3.Media Layer
The media layer enables all the graphics, audio and video technology of the
system. The different frameworks are:
UIKit Graphics
This provides support for designing images and animating the view content.
Core Graphics Framework
This provides support for 2-D vector and image based rendering and is the native
drawing engine for iOS apps.
Core Animation
The Core Animation technology optimizes the animation experience of the apps.
Media Player Framework
This framework provides support for playing playlists and enables the user to use
their iTunes library.
AV Kit
This provides various easy to use interfaces for video presentation.

25. 4.COCOA TOUCH
COCOA Touch is also known as the application layer
which acts as an interface for the user to work with
the iOS Operating system. It supports touch and
motion events and many more features
Swapnali Pawar

26. 4.Cocoa Touch Layer-
The cocoa touch layer provides the following frameworks −
EventKit Framework
This shows the standard system interfaces using view
controllers for viewing and changing calendar related events.
GameKit Framework
This provides support for users to share their game related
data online using Game center.
MapKit Framework
This provides a scrollable map which can be included into the
app user interface.
