返回的所有可能值是多少[[UIDevice currentDevice] model];？它不是有记录的 http://developer.apple.com/library/ios/#documentation/uikit/reference/UIDevice_Class/Reference/UIDevice.html.

可能的值为iPod touch, iPhone, iPhone Simulator, iPad, iPad Simulator

如果你想知道哪些硬件iOS正在毁掉像iPhone3, iPhone4, iPhone5下面是其代码

NOTE:下面的代码可能不包含所有设备的字符串，我和其他人正在维护相同的代码GitHub所以请从那里获取最新的代码
