IOS 6 programming practices

Original Title: iOS 6 programming pushing the limits Author: (US) ROB Napier mugunth Kumar [Translator's introduction] Translator: chen xiaoliang Wu Haifeng Deng Qiang Zhou Qingcheng series name: Turing Program Design Series Press: People's post and telecommunications Press ISBN: 9787115312181 Release Date: April 2013 published: 16: 1-1 category: Computer> Software and programming> mobile development> other mobile development technologies
For more information, see "iOS 6 programming practices" Introduction to the constantly evolving computer books and iOS platform. This book is fully updated based on this and covers iOS 6 development in four parts. The first part mainly introduces the new functions of iOS 6. The second part shows you how to master common tools (including table view notifications and animation layers ), the content involves cocoa design patterns and ideas Apple uses to solve problems, manages memory through objective-C's arc, and correctly uses table views (including solving infinite scrolling and other issues), set view and automatic layout, custom drawing, view animation and core animation framework, error handling, and location service. Part 3 describes the tools and related technologies to be used in specific situations, including table views, multitasking, restful services, and security (using Key Strings, certificates, and passwords to protect applications and user data) adjust applications based on hardware and platform, easily create internationalization and localization, purchase in-app, and use instruments for performance tuning. The fourth part introduces more advanced development tools, including storyboards and custom switching effects, KVO, block and function programming, offline support, cloud, text layout, and core Foundation, finally, the objective-C is parsed in depth. IOS 6 Programming Practice is suitable for people with certain iOS development experience who are committed to in-depth understanding of iOS development, best practices, and others' practical development experience.
