class-dump is a command-line utility for examining the Objective-Csegment of Mach-O files. It generates declarations for the classes,categories and protocols. This is the same information provided byusing ‘otool -ov’, but presented as normal Objective-C declarations.
1.下载安装包
http://stevenygard.com/projects/class-dump/,
这里我下载的是 class-dump-3.5.dmp。然后把
放到/usr/local/bin
目录下,
在终端输入 class-dump
,显示 class-dump的版本后,就可以正常使用 class-dump 命令了。
正确安装后如下图所示:
2.使用方法
命令如下:class-dump -H /Applications/Calculator.app -o /Users/apple/Desktop/calculate\ heads
解释:
/Applications/Calculator.app
是计算器app的路径
/Users/apple/Desktop/calculate\ heads
是存放dump出来头文件的文件夹路径
结果如下:
利用 class-dump 可以导出 AppKit,UIKit。。。
class-dump AppKit:class-dump /System/Library/Frameworks/AppKit.framework
class-dump UIKit:
class-dump /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk/System/Library/Frameworks/UIKit.framework
