Objective-C for absolute beginners : iPhone, iPad, and Mac programming made easy

It seems as if everyone is writing applications for Apple’s iPhone and iPad, but how do they all do it? It’s best to learn Objective-C, the native language of both the iOSand Mac OS X, but where to begin? Right here, even if you’ve never programmed before!Objective-C for Absolute Beginners will teach you how to write software for your Mac, iPhone,or iPad using Objective-C, an elegant and powerful language with a rich set of developer tools. Using a hands-on approach, you’ll learn to think in programming terms, how to use Objective-C to build program logic, and how towrite your own applications and apps.With over 50 collective years in software development and based on an approach pioneered at Carnegie Mellon University, the authors have developed a remarkably effective approach to learning Objective-C. Since the introduction of Apple’s iPhone, theauthors have taught hundreds of absolute beginners how to develop Mac, iPhone,and iPad apps, including many that became popular apps in the iTunes App Store.What you’ll learnThe fundamentals of computer programming: how to understand variables,design data structures, and work with file systemsThe logic of object-oriented programming: how to use Classes, Objects, and MethodsThe flexibility of Apple#226;?TMs developer tools: how to install Xcode and write programs in Objective-CThe power of Cocoa and Cocoa touch: how to make Mac OS Xapplications or iOS apps that do cool stuffWho this book is forEveryone!
