Learn the tools most essential for building high-quality applications for Mac OS X, iPhone, and iPod touch. This thorough introduction to Apple's Cocoa programming environment and its Objective-C language quickly gets you up to speed with step-by-step tutorials, hands-on tasks, and numerous examples. With clear instruction from Scott Stevenson, the Cocoa programmer behind Cocoa Dev Central, you'll learn just enough foundation and theory to ground you before jumping right into building applications, managing events, creating GUIs, and more with Cocoa and the Application Kit. You also get skill-building exercises, and key input from a Cocoa expert on the best use of these tools. This book is still in progress, but you can get going on this technology through our Rough Cuts edition, which lets you read the manuscript as it's being written , either online or via PDF.
