Download the demo Xcode project from: http://db.tt/14dtriGU SESSION ABSTRACT You’ve been a .NET developer for the last 10 years. You love Visual Studio. You can spit out C# like a boy scout can tie a knot. But now your boss wants you to build an iPad app for the company. Or maybe you got a good deal on a Mac on eBay and you’ll finally write that cool iPhone app that will top the other 600K in the iOS App Store. So where do you get started? What development environment do you use? How do you write apps in Objective-C compared to C#? What other tools & libraries can you use? This session is your survival guide to the world of iOS development as seen from the eyes of a .NET developer. We’ll start from the basics and build our first iOS app, using analogies and comparisons from the familiar world of Visual Studio and .NET as our guide. We’ll also discuss how to structure our app project, how to test & deploy our app, and we’ll even take a quick look at some of the new developer features in iOS 7. We'll also discuss how to cloud-enable your apps using Microsoft Azure Mobile Services, which features native support for iOS developers. You’ll learn to blend in with the Apple crowd and talk like a true native in no time! If you’ve ever considered dipping your toes in the iWaters, this session is your chance to take your first dive.

3. Disclaimers & Assumptions
• You know little to nothing about iOS development
• You’re a .NET developer: C# (or VB.NET), Visual Studio, XAML, ASP.NET,
Windows Forms, etc.
• You know some basics of Microsoft device development: Windows 8/RT
or Windows Phone
• You have access to a Mac, and preferably an iPad or iPhone too
• You want to learn the “native” iOS dev basics: Xcode & Objective C
– I am NOT covering mobile design considerations
– I am NOT covering Xamarin.iOS / MonoTouch, Appcelerator,
or Hybrid HTML5 App Development with PhoneGap

App Store
• Register an account at
developer.apple.com
• $99 / year to deploy to
actual devices & publish to
the App Store
Install Xamarin.iOS
• Aka “MonoTouch”
• Yes, you still need a Mac to
build iOS apps
• Free Starter Edition at
Xamarin.com
• $299 for Indie Edition: no
size limit + components
Install Other Tools
• UI Controls

MICROSOFT .NET / C# DEVELOPER APPLE IOS OBJECTIVE-C DEVELOPER
ArrayList myList;
myList = new ArrayList();
myList.Add("Welcome! ");
int currentIndex = 0;
string message = myList.Item[currentIndex];

NSMutableArray *myList;
myList = [[NSMutableArray alloc] init];
[myList addObject:@"Welcome!"];
int currentIndex = 0;
NSString *message = [myList
objectAtIndex:currentIndex];
[textField setText:message];

16. iOS & the Model View Controller
• Using the MVC pattern is mandatory in Xcode for iOS projects based on UIKit
– No code behind. All code goes in Controller
– Apple decided for you. Don’t fight it
• Facilitates the development of Universal iOS apps for iPhone and iPad
• UIKit provides a system for navigating between Views and Controllers
– Includes Visual Transition
• Xcode provides drag & drop interactions
to connect Views and Controllers
– Actions and Outlets

(x86 / x64) by the CLR
• Garbage Collection built-in and
automatically managed by the CLR
.NET iOS & Xcode
• Objective C compiled straight to native
machine code
• Previous version of Xcode used to give
developers compiler warnings about
refs
• Automatic Reference Counting (ARC)
provides a mechanism to help prevent
orphan objects & leaks
• ARC works at compile time, inserts the
Retain & Release code for you

• Push (aka remote) notifications
– Introduced in iOS 3.0 & OS X version 10.7 (“Lion”)
– Apps must register to receive push notifications
– Apple Push Notification service (APNs) is required

– Max size for notification payload is 256 bytes
• Local Notifications
– Introduced in iOS 4.0; not available in OS X
– Local notifications are scheduled by an app
• Local and push notifications look &
sound the same when shown

30. iOS Push: from Provider to Device
• Providers push to many devices
• Devices can receive push notifications from many providers
• APN Service includes
a default Quality of
Service (QoS)
component that
performs a
store-and-forward
function

31. • Hugely scalable push notifications
• Cross platform (including iOS & Android)
• Independent of storing data in cloud
• Push to a single user or millions
• Client and server registration
• Watch “Push Notifications to Any Client
with Notification Hubs”
