class-dump
顾名思义就是来dump头文件的工具, 简单好用
下载地址
先下载class-dump.dmg, 然后把里面的class-dump复制出来就可以用了, 如果希望直接运行可执行文件那么加到/usr/bin里.
但是macos的限制, /usr/bin不让写文件, 可以参考这里修改权限.
然后直接复制到/usr/bin下,
chomd 777 /usr/bin/class-dump
直接调用 class-dump使用即可.
另一种在自己的用户目录下配置(推荐)
在当前用户新建一个bash_profile
mkdir ~/bin
mv ../class-dump ~.bin
open -e .bash_profile 输入 export PATH=$HOME/bin/:$PATH
source ~/.bash_profile
就可以了(后面theos的一些配置也可以放在bash_profile里, 还是比较方便的).
在dump有swift类可能会报错

运行实例
class-dump
class-dump 3.5 (64 bit) (Debug version compiled Sep 17 2017 16:24:48)
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)
一般用法
找到对应的xxx.app文件, 然后定位app的可执行文件
cd SpringBoard.app
plutil -p info.plist | grep CFBundleExecutable
"CFBundleExecutable" => "SpringBoard"
class-dump -S -s -H SpringBoard -o ~/hfiles/SpringBoardHeaders
至此SpringBoard的所有头文件就dump出来了

至于如何导出SpringBoard.app, 首先是需要一台越狱的设备, 使用SSH或者其他文件管理从手机中导出, 这里不多赘述, 会有其它文档详细介绍, 这里只记录工具的配置和基本使用.
