如何通过代码查找 iPhone/iPod 设备型号（3G、3GS、4、4S）？ [复制]

Question

可能重复：
Determine device (iPhone, iPod Touch) with iOS

我已尝试获取当前设备型号名称，例如 3G、3GS、4、4S、iPodTouch（不同代）。但是，直到现在我还不能得到确切的结果。你能帮我找出设备型号吗？在这里我附上了我用来获取设备型号的代码。

UIDevice *device = [UIDevice currentDevice];
NSString *deviceVersion = [device systemVersion];//Return 4.0.1 and 5.0.1
NSString *deviceName = [device systemName];//Return iPhone, iPod Touch

如何获取设备型号 3G,3GS,4,4S,iPod Touch,iPad？

Answer 1

#import <sys/utsname.h>

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

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

结果应该是：

@"i386"      on the simulator
@"iPod1,1"   on iPod Touch
@"iPod2,1"   on iPod Touch Second Generation
@"iPod3,1"   on iPod Touch Third Generation
@"iPod4,1"   on iPod Touch Fourth Generation
@"iPhone1,1" on iPhone
@"iPhone1,2" on iPhone 3G
@"iPhone2,1" on iPhone 3GS
@"iPad1,1"   on iPad
@"iPad2,1"   on iPad 2
@"iPhone3,1" on iPhone 4
@"iPhone4,1" on iPhone 4S
