检测特定的iPhone/iPod touch型号

可能重复：

我正在制作一款游戏，它利用了iPhone的点对点蓝牙功能，可能还有第二代iPod touch。然而，为了阻止用户尝试在iPod1st gen和iPhone2G上玩多人游戏，我需要检查具体的设备型号

[[UIDevice currentDevice]model]只会告诉我该设备是iPhone还是iPod touch。有没有办法检查具体的设备型号，比如：iPhone3GS、iPodtouch第一代或其他什么

编辑：

UIDevice有一个类别，我认为它是由Erica Sadun创建的，我不认为它使用以下代码来获得特定的设备型号。您可以在此处找到整个类别以及其他有用的内容：

这是可行的，使用它的应用程序最近已在AppStore中获得批准。

您可以从sys/utsname.h使用uname获得设备型号。例如：

#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 @"iPad3,1" on iPad 3 (aka new iPad) @"iPhone3,1" on iPhone 4 @"iPhone4,1" on iPhone 4S @"iPhone5,1" on iPhone 5 @"iPhone5,2" on iPhone 5

最完整的UIDevice硬件类别可能由Erica Sadun提供：

[[UIDevice currentDevice] platformType]   // ex: UIDevice4GiPhone
[[UIDevice currentDevice] platformString] // ex: @"iPhone 4G"

然后检查字符串是否等于您要查找的任何设备，如：

if(value==@"iPod1,1" ) 
{}

你应该准备好了

iphone4是iPhone3,1和iPhone3,2 iPhone4S是iPhone4,1 iPad2是iPad2,1 iPad2,2和iPad2,3，具体取决于GSM等版本 iPad3是iPad3,1 iPad3,2和iPad3,3，具体取决于GSM等版本

这段代码怎么样？如果发布了新版本，您将使用最后知道的设备识别代码

    if ([aux rangeOfString:@"iPhone"].location!=NSNotFound) {

        if (version >= 4) return @"iPhone4s";

    }

谢谢你的回复。成功了！更正一下：iPhone3GS是iPhone2,1。干杯，谢谢。我已经用iPhone3GS的结果更新了答案。iPhone2Gen的系统信息是什么？它和iPhone 3G一样吗？@x86_64用于模拟器。我不确定是我还是什么，但当我在4、4s和5上测试时，它在开发过程中对我起了作用，但在生产过程中失败了，似乎根本不起作用，这导致了很多问题。这并没有返回准确的型号。只是它有高清或SD屏幕。这对我来说太完美了。我所需要知道的是设备是否有高分辨率，它今天不工作。我在[UIDevice currentDevice]中找不到platformType和platformString。@RobertYiJiang您添加了答案中链接的Github项目中的类吗？它仍然有效！您需要添加include not working a get output as x86_64In>SO问题，一个链接已发布到github.com/ars/uidevice extension/tree/master>此网站。非常重要：苹果建议不要使用此代码。这是因为在某些情况下，这可能会被错误地检测到。在3点30分查看WWDC 2011第123课时，你会看到他们展示了这段代码，并告诉你不要使用。@Lookez我们必须使用什么代码？我看了那个视频。不建议在检查iPad时使用这种代码，因为我们现在已经有了UI_用户_界面_习惯用法，但是没有提到使用它来确定具体的硬件模型。是的，在某些情况下，这并不是可以错误地检测到的，而是总是正确地检测到的。您只需对代码进行未来验证，而不必具有默认为特定版本的某些悬而未决的其他条件。如果有人提到为什么会有-11，但没有评论说明原因，那就太好了。代码[[UIDevice currentDevice]model]只返回iPhone或iPad，而不是型号。
