1、Cycript的基本用法

1.1、基本概念

Cycript是由Cydia创始人Saurik推出的一款脚本语言，Cycript混合了OC、JavaScript语法的解释器，这意味着我们能够在一个命令中使用Oc或者JavaScript，甚至两者并用。它能够挂钩正在运行的进程，能够在运行时修改很多东西。

1.2、Cycript 使用

1、Cycript 安装
下载Cycript这个可执行文件、放在 /opt/cycript_0.9.594 配置环境变量 export PATH=/opt/cycript_0.9.594:$PATH
2、运行 MonkeyDevDemo ，编译完成后，查看 app 的 Frameworks 中包含 libcycript.dylib 文件

libcycript.dylib
3、终端连接手机 cycript -r 192.168.3.9:6666 终端输入命令
UIWindow.keyWindow

(extern "C" id ":keyWindow"(id, SEL))

[UIApplication sharedApplication]

"<UIApplication: 0x113d1ca10>"

UIApp

"<UIApplication: 0x113d1ca10>"

var keyWd = UIWindow.keyWindow()

4、手机连接代理

命令脚本
可在终端输入命令：
pviews()、pvcs()

2、Cycript编写脚本

2.1、编写 cy 脚本

添加脚本
1、编写 test.cy 脚本

sum = function(a, b) {
    return a + b;
}

2、执行脚本
@import test && sum(10, 20)
