This is the second book in the Xcode Primer series and picks up where the first one left off. After the basics of C you need to learn Objective-C.
iOS iPhone and iPad developers use a mix of C and Objective-C every day. Use this book to learn to walk before you can run. Helps you make the transition from procedural C programming to wildly popular object oriented programming language that is Objective-C.
Covers OOP, the Objective-C syntax, building and consuming classes, the Foundation framework, the file system, 2 chapters with iOS and Mac OS X GUI development, a project chapter and many, many examples, exercises and code challenges.
Has Xcode screen shots for the latest version of Xcode 4 on Mac OS X Lion, a support video channel on YouTube and a free Xcode project download for the chapter 13 project.
