Xcode 4 Unleashed is the definitive guide to Xcode development for every Macintosh and iOS developer, regardless of their experience or the types of applications they create. Fritz Anderson brings more than a quarter-century of Mac development experience to this book. He systematically covers every Xcode feature and capability, from the absolute basics onward, and presents extensive new coverage of Xcode 4's improvements - including a thorough introduction to Xcode development for iOS (iPhone, iPad, and iPod touch). To make the book even more accessible to developers who are new to Apple's platforms, this edition begins with a brand-new basic overview of the Xcode environment, Interface Builder, Xcode's Documentation Viewer, and Xcode's most useful features.
