Cycript的使用方法

• Cycript的开启和关闭
  • 开启

  1. cycript
     cy#

  2. cycript -p 进程ID

  3. cycript -p 进程名称

注意:这几个操作都是开启操作，不可以同时进行,需要退出Cycript(control + D),才可以执行不同的指令

安装 App

MonkeyDev 这里有详细的说明 https://github.com/AloneMonkey/MonkeyDev/wiki/

刚注意到前天的 GitHub 被收购的消息，
微软正在收购GitHub

安装好 APP ，就可以使用 Cycript 调试。

• 常用语法

连接手机：

cycript -r 192.168.1.213:6666
ip + port，默认的端口就是6666，不进入cycript 环境连接。

当前应用对象：UIApp 或 [UIApplication sharedApplication]

定义变量：var 变量名 = 变量值
如：var keyWin = UIWindow.keyWindow 或 var keyWin = UIApp.keyWindow
但是我的 var keyWin = UIWindow.keyWindow 定义报错：

获取内存对象： keyWin.rootViewController
*"#"<QMSideMenuViewController: 0x109e23810>" *

通过内存地址获取对象：#0x109e23810
#"<QMSideMenuViewController: 0x109e23810>"

访问对象的属性：#0x109e23810.view
#"<UIView: 0x109b2d8c0; frame = (0 0; 375 667); autoresize = W+H; gestureRecognizers = <NSArray: 0x1c0640e70>; layer = <CALayer: 0x1c44271e0>>"

获取加载的所有OC类：ObjectiveC.classes (会崩溃)

获取对象的所有成员变量：*变量名称
eg: *keyWin

{
    isa: CPMotionRecognizingWindow,
    _hasOverrideClient: 0,
    _hasOverrideHost: 0,
    _hasInputAssistantItem: 0,
    _constraintsExceptingSubviewAutoresizingConstraints: @[],
    _cachedTraitCollection: null,
    _layer: # "<UIWindowLayer: 0x1c4426da0>",
    _layerRetained: # "<UIWindowLayer: 0x1c4426da0>",
    _enabledGestures: 0,
    _gestureRecognizers: @[#"<_UISystemGestureGateGestureRecognizer: 0x1c41c4740; state = Possible; delaysTouchesEnded = NO; view = <CPMotionRecognizingWindow 0x109b2c7e0>>", #"<_UISystemGestureGateGestureRecognizer: 0x1c41c4830; state = Possible; delaysTouchesBegan = YES; delaysTouchesEnded = NO; view = <CPMotionRecognizingWindow 0x109b2c7e0>>"],
    _window: null,
    _subviewCache: @[#"<UIView: 0x109b2d8c0; frame = (0 0; 375 667); autoresize = W+H; gestureRecognizers = <NSArray: 0x1c0640e70>; layer = <CALayer: 0x1c44271e0>>"],
    _templateLayoutView: null,
    _charge: 0,
.....
}

遍历打印某个视图的子控件：[变量名 recursiveDescription].toString()
如：[[UIApp keyWindow] recursiveDescription].toString()

< CPMotionRecognizingWindow: 0x109b2c7e0;
baseClass = UIWindow;
frame = (0 0; 375 667);
autoresize = W + H;
gestureRecognizers = < NSArray: 0x1c465f1a0 > ;
layer = < UIWindowLayer: 0x1c4426da0 >>
    |
    < UIView: 0x109b2d8c0;
frame = (0 0; 375 667);
autoresize = W + H;
gestureRecognizers = < NSArray: 0x1c0640e70 > ;
layer = < CALayer: 0x1c44271e0 >>

......

在内存里查找某个类型的对象：choose(类名）
如 choose(UITableViewCell)

• 快捷键

取消输入：Ctrl + C
退出：Ctrl + D
清屏：Command + R

Cycript 小练习

安装完 WeChat 后，进入 Cy 环境。

修改任意你想修改的内容， 输入代码后回车 即可注入

/** 显示通知个数 */
[[UIApplication sharedApplication] setApplicationIconBadgeNumber:666666] 
/** 隐藏状态栏 */
 [[UIApplication sharedApplication] setStatusBarHidden:YES]

// 修改转账的金额
1. choose(UILabel)
2. Command + F -> 金额 -> 获取控件内存地址
3.  # 0x11c159340.text = '88888888'
    #0x13baab450.textColor = [UIColor orangeColor]
    #0x13baab450.adjustsFontSizeToFitWidth = YES
OK , 搞定！！！
