从可执行文件列举出类名和方法名的工具
class-dump原理分析
- 处理输入参数
- 判断目标文件格式，确定目标架构
- 分别处理符号表、协议、类、分类
- 处理类型type
- 生成头文件
class-dump -H /Applications/Calculator.app -o /Users/GofLee/Desktop/CalculateHeads
将里面的class-dump拷贝到/usr/local/bin路径下,打开终端，在控制台输入class-dump，显示如下表示配置成功
class-dump 3.5 (64 bit) (Debug version compiled May 5 2019 20:55:23)
Usage: class-dump [options] <mach-o-file>
where options are:
-a show instance variable offsets
-A show implementation addresses
--arch <arch> choose a specific architecture from a universal binary (ppc, ppc64, i386, x86_64, armv6, armv7, armv7s, arm64)
-C <regex> only display classes matching regular expression
-f <str> find string in method name
-H generate header files in current directory, or directory specified with -o
-I sort classes, categories, and protocols by inheritance (overrides -s)
-o <dir> output directory used for -H
-r recursively expand frameworks and fixed VM shared libraries
-s sort classes and categories by name
-S sort methods by name
-t suppress header in output, for testing
--list-arches list the arches in the file, then exit
--sdk-ios specify iOS SDK version (will look for /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS<version>.sdk
or /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS<version>.sdk)
--sdk-mac specify Mac OS X version (will look for /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX<version>.sdk
or /Developer/SDKs/MacOSX<version>.sdk)
--sdk-root specify the full SDK root path (or use --sdk-ios/--sdk-mac for a shortcut)
