2. Objective-C Boot Camp

iOS development centers on Objective-C. It is the standard programming language for both the iPhone family of devices and for Mac OS X. It offers a powerful object-oriented language that lets you build applications that leverage Apple’s Cocoa and Cocoa Touch frameworks. In this chapter, you learn basic Objective-C skills that help you get started with iOS programming. You learn about interfaces, methods, properties, memory management, and more. To round things out, this chapter takes you beyond Objective-C into Cocoa to show you the core classes you’ll use in day-to-day programming and offers you concrete examples of how these classes work.
