Introduction to iOS with C# using Xamarin
1 like932 views
This document discusses using Xamarin to develop iOS apps using C#. Xamarin allows developers to write C# code and share code across iOS, Android, and other platforms. It works by using Mono, which implements .NET on mobile, and bindings that expose the iOS SDK in C#. The compiler produces native ARM binaries. Development can be done in Xamarin Studio on Mac or Visual Studio on Windows via a build host. Code signing and deployment require Xcode and the Apple developer program. Components and code can be shared between apps and with other developers.
Introduction to iOS with C# using Xamarin
- 1. iOS with C# using Xamarin Craig Dunn Developer Evangelist Xamarin craig@xamarin.com @conceptdev
- 2. Why Xamarin.iOS? aka Why Are You Here? • Write C# apps for iPhone, iPad and iPod • Share C# with other platforms: Xamarin.Android Windows Phone Windows Store Apps • • • • re-use C# from existing projects Create native iOS user interface Native app == native performance Entire iOS SDK directly accessible (StoreKit, iCloud, etc) You can add your own Objective-C libraries too
- 3. How Does it Work? • Mono C# + .NET implementation for Linux started in 2001/released 2004 perfect fit for today’s mobile platforms: iOS & Android • “Bindings” exposes iOS as C# you can write your own to incorporate any Objective-C • Compiler produces native ARM binary can link out unused code
