Chapter 30. Developing for iOS
Applications for the iPhone and iPad are written using Xcode and the Cocoa Touch Frameworks. Cocoa Touch comprises Foundation, Core Graphics, and UIKit. UIKit is analogous to AppKit, supplying the windows, events, views, buttons, and so on, for iPhone programmers. UIKit is, however, not the same as AppKit. This chapter will get you started developing applications on iOS, with an emphasis on what is not the same.
In particular, you will not have the garbage collector, but you can use ARC on iOS 5 or, if you choose, manual reference counting (retain/release) for memory management. You will use OpenGL ES instead of regular OpenGL. Windows and table-view cells are subclasses of UIView.
