Updated for OS X 10.9 Mavericks, iOS 7, and Xcode 5 Programming in Objective-C is a concise, carefully written tutorial on the basics of Objective-C and object-oriented programming for Apple's iOS and OS X platforms. The book makes no assumptions about prior experience with object-oriented programming languages or with the C language (which Objective-C is based upon). Because of this, both beginners and experienced programmers alike can use this book to quickly and effectively learn the fundamentals of Objective-C. Readers can also learn the concepts of object-oriented programming without having to first learn all of the intricacies of the underlying C programming language. This unique approach to learning, combined with many small program examples and exercises at the end of each chapter, makes Programming in Objective-C ideally suited for either classroom use or self-study. This edition has been fully updated to incorporate new Objective-C features and technologies introduced with Xcode 5, iOS 7, and Mac OS X Mavericks. "The best book on any programming language that I've ever read. If you want to learn Objective-C, buy it."-Calvin Wolcott "An excellent resource for a new programmer who wants to learn Objective-C as their first programming language-a woefully underserved market."-Pat Hughes
