I was wondering if it's possible to determine what kind of iPhone (for example) the currentdevice is? I know it's possible to get the model through NSString *deviceType = [[UIDevice currentDevice] model]; which will just return whether I have an "iPhone" or an "iPod", BUT I was wondering if it's possible to detect/know if I have an iPhone 3GS vs. and iPhone 4 vs. an iPhone 4S (in actuality, all I really want to do is determine if I have a 3G or not, because I'm doing fairly graphics intensive stuff).

所以,请告诉我,谢谢!

我也省略了详细的信息(例如:“型号A1507, A1516, A1526(中国),A1529 |全球”),并将其放在评论中,以防你想将其用作面向用户的字符串,而不是吓坏他们。


编辑:这个答案使用Swift 2提供了类似的实现。

编辑2:我刚刚添加了iPad Pro型号(两种尺寸)。型号等供日后参考。可以在iPhone Wiki中找到。

编辑3:增加对iPhone XS、iPhone XS Max和iPhone XR的支持。

编辑4:增加对iPhone 11、iPhone 11 Pro和iPhone 11 Pro Max的支持。

其他回答

为了节省别人的时间。 因为接受,必须投票回答建议库使用私人API和我的应用程序被拒绝,因为uidevice-extension就在昨天! 我切换到GBDeviceInfo库,安装为pod以及,现在它看起来不错,维护和更新到最新的设备。

我优化了NicolasMiari的实现,并添加了模拟器,在这里:

+ (NSString*)deviceName {

  static NSDictionary* deviceNamesByCode = nil;
  static NSString* deviceName = nil;

  if (deviceName) {
    return deviceName;
  }

  deviceNamesByCode = @{
    @"i386"      :@"Simulator",
    @"iPod1,1"   :@"iPod Touch",      // (Original)
    @"iPod2,1"   :@"iPod Touch",      // (Second Generation)
    @"iPod3,1"   :@"iPod Touch",      // (Third Generation)
    @"iPod4,1"   :@"iPod Touch",      // (Fourth Generation)
    @"iPhone1,1" :@"iPhone",          // (Original)
    @"iPhone1,2" :@"iPhone",          // (3G)
    @"iPhone2,1" :@"iPhone",          // (3GS)
    @"iPad1,1"   :@"iPad",            // (Original)
    @"iPad2,1"   :@"iPad 2",          //

    @"iPhone5,1" :@"iPhone 5",        // (model A1428, AT&T/Canada)
    @"iPhone5,2" :@"iPhone 5",        // (model A1429, everything else)
    @"iPad3,4"   :@"iPad",            // (4th Generation)
    @"iPad2,5"   :@"iPad Mini",       // (Original)
    @"iPhone5,3" :@"iPhone 5c",       // (model A1456, A1532 | GSM)
    @"iPhone5,4" :@"iPhone 5c",       // (model A1507, A1516, A1526 (China), A1529 | Global)
    @"iPhone6,1" :@"iPhone 5s",       // (model A1433, A1533 | GSM)
    @"iPhone6,2" :@"iPhone 5s",       // (model A1457, A1518, A1528 (China), A1530 | Global)

    @"iPad4,2"   :@"iPad Air",        // 5th Generation iPad (iPad Air) - Cellular
    @"iPad4,4"   :@"iPad Mini",       // (2nd Generation iPad Mini - Wifi)
    @"iPad4,5"   :@"iPad Mini"        // (2nd Generation iPad Mini - Cellular)
  };

  struct utsname systemInfo;
  uname(&systemInfo);
  NSString* code = [NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding];

  deviceName = [deviceNamesByCode objectForKey:code];

  if (!deviceName) {
    // Not found in database. At least guess main device type from string contents:

    if ([code rangeOfString:@"iPod"].location != NSNotFound) {
      deviceName = @"iPod Touch";
    } else if([code rangeOfString:@"iPad"].location != NSNotFound) {
      deviceName = @"iPad";
    } else if([code rangeOfString:@"iPhone"].location != NSNotFound){
      deviceName = @"iPhone";
    } else {
      deviceName = @"Simulator";
    }
  }

  return deviceName;
}

```

一个从NSString描述中脱离的类别

通常,在整个代码中避免任意的字符串比较是可取的。最好在一个地方更新字符串,并在应用程序中隐藏神奇的字符串。为此,我在UIDevice上提供了一个类别。

对于我的特定需求,我需要知道我正在使用的设备,而不需要知道可以通过其他方式轻松检索的网络功能的细节。因此,您将发现一个比不断增长的设备列表更粗粒度的枚举。

更新就是将设备添加到枚举和查找表中。

虽然这个问题在2012年就被提出了,但苹果仍然没有给出将设备模式标识符转换为设备名称的方法。 有很多答案依赖于硬编码这些名称,不幸的是,当苹果发布新设备时,这些名称很快就过时了。

我们需要的是一种方法来获得一个不断更新的列表,它就在这里:https://github.com/ptrkstr/Devices

每次添加新设备时,这个Swift包都会更新,你所需要做的就是更新你的依赖项来获得它们。
