- Cycript是Objective-C++、ES6(JavaScript)、Java等语法的混合物
- 可以用来探索、修改、调试正在运行的Mac\iOS APP
- 官网: http://www.cycript.org/
- 文档: http://www.cycript.org/manual/
- 通过Cydia安装Cycript,即可在iPhone上调试运行中的APP(软件源:http://apt.saurik.com)
Cycript语法
一、Cycript的开启和关闭
- 开启
cycript
、cycript -p 进程ID
、cycript -p 进程名称
ps(process status)命令可以列出系统当前的进程
- 安装adv-cmds
列出所有的进程
ps –A
、ps aux
搜索关键词
ps –A | grep 关键词
- 取消输入:
Ctrl + C
- 退出:
Ctrl + D
- 清屏:
Command + R
二、Cycript的常用语法
-
UIApp
:[UIApplication sharedApplication]
的简写
cy# [UIApplication sharedApplication]
#"<SMReaderApp: 0x147e22e50>"
cy# UIApp
#"<SMReaderApp: 0x147e22e50>"
- 定义变量:var 变量名 = 变量值
cy# var app = UIApp.keyWindow
#"<TQWindow: 0x147d22440; baseClass = UIWindow; frame = (0 0; 375 667); gestureRecognizers = <NSArray: 0x1702577f0>; layer = <UIWindowLayer: 0x170223000>>"
cy# app.rootViewController
#"<BaseViewController: 0x148032a00>"
- 用内存地址获取对象:
#内存地址
cy# UIApp
#"<SMReaderApp: 0x147e22e50>"
cy# #0x147e22e50.keyWindow
#"<TQWindow: 0x147d22440; baseClass = UIWindow; frame = (0 0; 375 667); gestureRecognizers = <NSArray: 0x1702577f0>; layer = <UIWindowLayer: 0x170223000>>"
cy# #0x147d22440.rootViewController
#"<BaseViewController: 0x148032a00>"
- 查看对象的所有成员变量:
*对象
cy# *UIApp
{isa:SMReaderApp,_delegate:#"<SMReaderApp: 0x147e22e50>",_exclusiveTouchWindows:[NSSet setWithArray:@[]]],_event:#"<UIInternalEvent: 0x1702205c0>",
- 递归打印view的所有子控件(跟LLDB一样的函数)
view.recursiveDescription().toString()
cy# UIApp.keyWindow.rootViewController.view.recursiveDescription() .toString()
"<UILayoutContainerView: 0x147e36250; frame = (0 0; 375 667); autoresize = W+H; gestureRecognizers = <NSArray: 0x17444c060>; layer = <CALayer: 0x170235a20>>\n | <UINavigationTransitionView: 0x147d29f70; frame = (0 0; 375 667); clipsToBounds = YES; autoresize = W+H; layer = <CALayer: 0x17423ab40>>\n | | <UIViewControllerWrapperView: 0x147e61de0; frame = (0 0; 375 667); autoresize = W+H;
- 筛选出某种类型的对象
choose(UIViewController)
choose(UITableViewCell)
cy# choose(UIViewController)
[#"<StatusBarController: 0x147e354b0>",#"<PRRootMoveViewCtrl: 0x147e3a5c0>",#"<BookStoreTabPageViewCtrl: 0x147e55960>",#"<BookShelfCtrl: 0x147ed4500>",#"<BookPageViewCtrl: 0x149022730>",#"<LeftMenusViewCtrl: 0x147d3b100>",#"<BookPageViewCtrl: 0x147f429a0>",#"<UIInputWindowController: 0x148815200>",#"<BookShelfNavCtrl: 0x148919a00>",#"<BookPageNavigationCtrl: 0x148961e00>",#"<PRNavigationController: 0x148029200>",#"<BaseViewController: 0x148032a00>",#"<PRNavigationController: 0x148079200>",#"<BookPageNavigationCtrl: 0x14807cc00>",#"<BookPageNavigationCtrl: 0x14814da00>"]
封装Cycript
- 我们可以将常用的Cycript代码封装在一个.cy文件中
- exports参数名固定,用于向外提供接口
(function(exports) {
// keyWindow
exports.KeyWin = function() {
return UIApp.keyWindow;
};
// 根控制器
RootVc = function() {
return UIApp.keyWindow.rootViewController;
};
})(exports);
存放和使用.cy文件
- 将.cy文件存放到/usr/lib/cycript0.9目录下
zhanglingli@bogon ~ % scp -P 10010 ~/Desktop/mjcript-master/mjcript.cy root@localhost:/usr/lib/cycript0.9
mjcript.cy 100% 6178 1.8MB/s 00:00
zhanglingli@bogon ~ %
- 在Cycript中引用.cy文件,并使用它提供的接口
cy# @import mjcript
{}
cy# MJAppId
@"com.book.yueliao"
cy# MJAppPath
@"/private/var/mobile/Containers/Bundle/Application/60903954-D55C-46F3-A655-A1739CE983EE/YueLiao.app"
cy# MJKeyWin
function () {return UIApp.keyWindow;}
cy# MJKeyWin ()
#"<TQWindow: 0x147d22440; baseClass = UIWindow; frame = (0 0; 375 667); gestureRecognizers = <NSArray: 0x1702577f0>; layer = <UIWindowLayer: 0x170223000>>"
cy# MJR
MJRectMake MJRootVc
cy# MJRootVc ()
#"<BaseViewController: 0x148032a00>"
