iOS 4 in action

the long version

A detailed, hands-on guide that goes from setting up your development environment all the way to creating a polished, commercial iOS 4 application. Examples include a chat client, a video game, an interactive map, and background audio. The book covers iOS SDK 4.3, mastering Xcode 4, multitasking for iPhone and iPad, Game Center, iAd, AirPrint, local and push notification, and implementing in-app purchasing. No previous iPhone or iPad know-how needed. Familiarity with C, Cocoa, or Objective-C helps but is not required.
