GETTING STARTED WITH XAMARIN.iOS

WHAT IS XAMARIN.iOS?

Xamarin.iOS & Xamarin.Android• Platform for native iOS/Android development using C#

• Formerly known as ‘MonoTouch’ and ‘Mono for Android’

• Based on Mono (.Net runtime for Linux platforms)

• Provides .Net library on iOS/Android

Xamarin.iOS & Xamarin.Android (continued)•Uses C# as the backing language with native platform

layouts (XIB on iOS, Android XML on Android)

•Wraps native libraries for each platform with C# wrappers through a process known as ‘projection’

• Full access to native libraries + simplifications in areas

Xamarin.Mobile• Library which provides common device functionality across

iOS, Android, and Windows

• Provides access to contacts, camera, and geo-location

MonoTouch.Dialog• iOS library to quickly create table based layouts through

simplified elements

BUILDING XAMARIN.iOS APPS

iOS Development Basics•MVC Architecture (Code)

• Storyboards vs XIBs (UI)

• Storyboards are newer and combine all views into one storyboard which can control user flows and segues

• XIBs are older and define a single screen

Xamarin Studio (or Visual Studio)

• Recently re-designed IDE from Xamarin

• Awesome IDE, like a simpler Visual Studio

•Component Store for common libraries and UI controls

XCode (or Xamarin Studio)

• XCode Interface Builder is how native iOS apps are built

• Xamarin Studio adding its own interface designer soon (currently in Alpha channel)

CROSS PLATFORM

Native• 100% native platform experience

• No code share with other platforms

• Differing code and UI tech per platform

Appcelerator Titanium Phonegap

Xamarin• 100% native platform experience

• Code share with all other platforms

• Differing UI tech per platform

• C#

• Javascript SDK which defines and interacts with native controls

• SDK may not support all controls or provide all native interfaces

• JS

• Web browser in an app with JS wrappers for native calls (GPS, Camera, etc.)

Sencha Touch• Web controls that mimic native

applications
