Before programmers can master Cocoa and write state-of-the-art software for Mac OS X, iPhone, iPad, or iPod touch, they must first understand the essentials of Objective-C. In this book, the world's leading Mac development trainers bring together all the knowledge programmers will need to program effectively with the latest version of this powerful language. The authors first review the basics of C, the language Objective-C is based on. Next, they systematically introduce today's best practices for object-oriented programming with Objective-C.   This edition covers new features of the Objective-C language including number/array/dictionary literal syntax, boxing, and subscripting and the most recent best practices and style guidelines. It also includes more information on advanced Objective-C and the Objective-C runtime and is updated for the latest version of Xcode.
