获取当前设备的型号,不依据屏幕size判断设备型号 如iPhone6 对应的deviceModelString: iPhone7,2



//需#import "sys/utsname.h"  

- (NSString*)deviceModelString

{

    struct utsname deviceInfo;

    uname(&deviceInfo);

    NSString * deviceModel = [NSString stringWithCString:deviceInfo.machine encoding:NSUTF8StringEncoding];

    return deviceModel;

}


// NSString * model = [[UIDevice currentDevice] model]; 该方法只能判断 设备的类型(@"iPhone", @"iPod touch"),无法判断具体型号
