IOS Android 手机助手原理以及源码（iTunesMobileDevice.dll 函数）

       IOS 手机助手第一步就是需要发现并且自动识别设备，iTunes 使用 iTunesMobileDevice.dll 来实现（mac 下面用的Mobiledevice.Framework）。 iTunesMobileDevice.dll 导出了很多函数，这些用来连接设备，操作设备上的文件系统，启动设备服务等等。如果是识别和连接手机话的话，仅仅只需要使用这个dll 就可以了。我们可以使用IDA 工具来查看dll的导出函数。

IDA 这个工具是一个静态反汇编工具，非常强大，可以查看模块的导出函数，而且还能看到函数的参数个数，以及参数占用的字节数。

比如导出函数

AMDeviceNotificationSubscribe 双击这个函数名字，然后F5 按键，就可以看到函数的一些声明信息

下面是助手需要用到的所有的导出函数
