✦ Synopsis

Objective C 2.0 is the object-oriented language that is the basis for Cocoa and Cocoa Touch, the development environment for the iPhone/iPod Touch. You'll learn all the basics: from handling data and creating functions to managing memory and handling exceptions. For programmers who want to develop iPhone apps, it's a must, and this title in the Visual QuickStart-style is the easy, fast way to get started.
