ios，设备标签与设备型号的对应关系(包含6plus)

今天遇到一款6plus的设备[UIScreen mainScreen].bounds.size.height打印出来是667，我表示还是比较吃惊的，然后就通过设备型号来判断手机到底是6plus还是其他的手机：

#import  // import it in your header or implementation file.

NSString* deviceName()
{
    struct utsname systemInfo;
    uname(&systemInfo);

    return [NSString stringWithCString:systemInfo.machine
                              encoding:NSUTF8StringEncoding];
}

结果打印出得string与型号之间的对应信息：
