Objective -C 的介绍
Objective-C是苹果Mac OS X 上开发的首选语言，主要是因为Mac OS X 技术源自NextStep的OpenStep操作系统， 因为OPENSTEP的软件架构（framework) ， 都是用Objetive-C 写成，所以MacOS X上的开发最佳语言自然也就是Objective-C 。
Object-C是由 Brad Cox在８０年代初在第一个纯面向对象语言Smalltalk基础上写成。后来他创立了StepStone公司从事Objective-C的推广。１９８８年，Steve Jobs的NextStep采用Objective-C作为开发语言，１９９２年GNU gcc编译器中包含了对Objective-C的支持（gnu-objc runtime)， Dennis Glating 写了第一个run-time。
