首先感谢 https://www.diffit.cn/2019/10/09/RunAppAsRootForXcode/ 作者 帮助我解决了困扰我很久的root权限问题 就有一点entitlements签名有点困惑 文件位置不是很清晰 本篇文章只是注明entitlements的文件位置
同时拓展了在root权限下获取UDID之类的api
注意事项
- 测试环境
- macOS: 10.14.6
- iPhoneOS: iOS11.0、iOS12.0、
- iPhone机型：两个iPhone6
- 越狱工具：unc0ver3.6.2
- 没有测试：iOS13和iOS10，也许可以。
- 关于链接
- 阅读本文前，请首先阅读 RunAppAsRootForTheos理论部分
- 此文使用Xcode新建的App，如果使用Theos新建的App，请转入RunAppAsRootForTheos
- 实现目标：点击按钮执行killall -9 SpringBoard,注销SpringBoard
App代码
- 本案例中使用Xcode新建的项目名称叫RootApp
- 在Xcode中找到main.m,添加setuid(0),设置uid

- 代码写完后，进行编译，编译完成后把RootApp.app放入iPhone上的/Applications里面
运行App
- SSH登录iPhone，执行以下命令，要不然看不到App图标
~ root# uicache
- 更改二进制文件权限，要不然App不能启动
~ root# chmod 755 /Applications/RootApp.app/RootApp
- 至此App可以成功打开
设置euid
~ root# chmod u+s /Applications/RootApp.app/RootApp
- 执行killall -9 SpringBoard，然后重新打开App，点击按钮，这个时候打印出来uid和euid为0
- 虽然uid和euid为0但是不能注销SpringBoard，因为需要可执行文件签权
可执行文件签权
- 新建RootApp.entitlements文件，内容为
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs /PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>com.apple.private.security.no-container</key>
<true/>
<key>com.apple.private.skip-library-validation</key>
<true/>
<key>platform-application</key>
<true/>
</dict>
</plist>
- 将RootApp.entitlements放到app文件内
ldid -SRootApp.entitlements RootApp
