Objective-c编程概念（一）简介

Many of the programmatic interfaces of the Cocoa and Cocoa Touch frameworks
only make sense only if you are aware of the concepts on which they are based. These concepts express the rationale for many of the core designs of the frameworks. Knowledge of these concepts will illuminate your software-development practices.

在Cocoa和Cocoa Touch框架中有很多编程接口，只有在你知道它们所基于的一些基本概念后，才能更好的理解它们。这些基本概念解释了这些框架很多核心设计的原理。对这些概念的掌握能照亮你软件开发的实践之路。
