iOS Programming (4th Edition)

This book is a hands-on tutorial distilled from Big Nerd Ranch's acclaimed 'iOS beginner bootcamp' course and is the 4th edition of the iOS Programming series. Fully rewritten for the iOS 7 and Xcode 5 development environment, it begins with Objective-C fundamentals and new language features, then moves progressively into common design patterns in the Cocoa frameworks, use of the Xcode and Instruments debugging tools, the view hierarchy, view controllers, Auto Layout, animation, data persistence, multithreading, network access, camera and maps, and every other stage of iOS app development. Unlike manuals that merely list APIs, the book is built around example apps you can complete yourself: requirements and design come first, then step-by-step interface building, coding, and debugging, and finally exercises—bronze, silver, and gold challenges—to help readers truly understand why the code is written as it is. The authors share extensive practical experience on naming conventions, memory-management conventions, subclass initialization, and choosing data-persistence methods in iOS development, making the book suitable both for complete beginners who want to start quickly with Chapters 1 and 2 and for experienced developers filling gaps and organizing their knowledge. This edition is a 16-format paperback of about 560 pages and 940,000 Chinese characters.
