Beginning Mac programming : develop with Objective-C and Cocoa

Beginning Mac Programming takes you through concrete, working examples, giving you the core concepts and principles of development in context so you will be ready to build the applications you've been imagining. It introduces you to Objective-C and the Cocoa framework in clear, easy-to-understand lessons, and demonstrates how you can use them together to write for the Mac, as well as the iPhone and iPod. You'll explore crucial developer tools like Xcode and Interface Builder, and learn the principles of object-oriented programming, and how memory, data, and storage work to help you build your software. If you've ever wanted to develop software for the Mac, this book is for you.
