iOS逆向工程(三):利用Cycript调试App

利用Cycript调试App

一、Cycript是什么?
二、Cycript的用法
例如:想挂载皮皮虾App,先让皮皮虾App在手机里跑起来,找到进程名后,输入以下命令
cycript -p Super
1>.使用前提:MacSSH登录了iPhone,iPhone安装了Cycript
2>.ps -A , 找出所有进程
3>.cycript -p Super,挂载皮皮虾,出现cy#,说明进入到了Cycript环境
三、Cycript的常用语法
四、封装并导入Cycript库
(function(exports){
    // app id
    AppId = [NSBundle mainBundle].bundleIdentifier;

    // mainBundlePath
    BundlePath = [NSBundle mainBundle].bundlePath;

    // keyWindow
    KeyWin = function() {
        return UIApp.keyWindow;
    };

    // rootView
    RootVc =  function() {
        return UIApp.keyWindow.rootViewController;
    };
})(exports);
五、在iOS12及以后的系统,挂载进程的方法
assert($mach_task_self != NULL)
*** _assert(status == 0):../Inject.cpp(143):InjectLibrary
六、知识点总结
1>.使用Cycript调试APP的前提:用Mac以SSH的方式登录了iPhone,iPhone安装了Cycript
2>.ps -A , 找出所有进程,找到要调试的APP
3>.以皮皮虾APP为例,挂载皮皮虾APP的进程:
- iOS12系统以前的挂载 :cycript -p Super
- iOS12系统以后的挂载 :cyrun -n Super -e -d -f 或者 cyrun  -b  bundleID -e
4>. 挂载后,会进入cycript环境,导入封装好的库,使用其中的方法进行调试: @import mjcript
5>. 找到皮皮虾APP的当前控制器: MJFrontVc()
6>. 退出cycript环境:Control + D
七、修改皮皮虾APP界面
songpengdeMBP:~ songpeng$ sh login.sh
iPhone7ceshiji:~ root# cyrun -n Super -e -d -f
applicationName: Super is not running (-1)
    executableName: Super
    bundleIdentifier: com.bd.iphone.super
    Cycript is inactive:
    Device is not passcode locked
    Tweak Mode
Waiting for Cycript to become active...
Successfully enabled, you may now run
    cycript -r 127.0.0.1:8556
