《Objective-C 编程》(Programming in Objective-C)英文PDF资源
This new edition of Programming in Objective-C incorporates numerous updates and improvements throughout the book:
Improved organization for some chapters
Incorporation of feedback and suggestions from members of the author's forum for readers, including more detailed descriptions for some of the examples
A new introduction to blocks with examples
Replacement of deprecated methods with newer methods
Updated diagrams and steps for using Xcode 4
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. While the Objective-C language itself has gone through minimal changes since the introduction of Objective-C 2.0, the Apple development tools that programmers use for Objective-C development on the Mac and on iOS have changed significantly in a relatively short period of time.
