Objective-C Pocket Reference

Objective-C is an exciting and dynamic approach to C- based object-oriented programming. It is the approach adopted by Apple as the foundation for programming under Mac OS X, a Unix-based operating system gaining wide acceptance among programmers and other technologists. Objective-C is easy to learn and has a simple elegance that is a welcome breath of fresh-air after the abstruse and confusing C++. Objective-C Pocket Reference provides a quick and concise introduction to Objective-C for beginner and experienced programmers alike. In addition to covering the essentials of Objective-C syntax, it also covers important facets of the language such as memory management, the Objective-C runtime, dynamic loading, distributed objects, and exception-handling.
