class-dump，分析可执行／app文件的函数定义

class-dump是一个开源项目，可以从http://www.codethecode.com/projects/class-dump/下载。

下面是我对自己写的一个demo程序，GKDemo.app用class-dump解析后得到的结果：

note: /Users/tonys/Library/Developer/Xcode/DerivedData/GKDemo-bgpwxsribkdlyphduyucdubnqbed/Build/Products/Debug-iphoneos/GKDemo.app是app所在的目录。

nicktest:Work tonys$ ./class-dump  /Users/tonys/Library/Developer/Xcode/DerivedData/GKDemo-bgpwxsribkdlyphduyucdubnqbed/Build/Products/Debug-iphoneos/GKDemo.app
