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!

我已经创建了plist文件,以帮助您获得每个设备的完整名称(源代码就在我的答案的末尾)

根据OhhMee的回答,你可以这样使用:

斯威夫特4.0

static func deviceName() -> String {

        var systemInfo = utsname()
        uname(&systemInfo)

        guard let iOSDeviceModelsPath = Bundle.main.path(forResource: "iOSDeviceModelMapping", ofType: "plist") else { return "" }
        guard let iOSDevices = NSDictionary(contentsOfFile: iOSDeviceModelsPath) else { return "" }

        let machineMirror = Mirror(reflecting: systemInfo.machine)
        let identifier = machineMirror.children.reduce("") { identifier, element in
            guard let value = element.value as? Int8, value != 0 else { return identifier }
            return identifier + String(UnicodeScalar(UInt8(value)))
        }

        return iOSDevices.value(forKey: identifier) as! String
    }

不要忘记在桥接头中添加#import <sys/utsname.h>。

Objective - C

#import <sys/utsname.h>

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

    NSString *iOSDeviceModelsPath = [[NSBundle mainBundle] pathForResource:@"iOSDeviceModelMapping" ofType:@"plist"];
    NSDictionary *iOSDevices = [NSDictionary dictionaryWithContentsOfFile:iOSDeviceModelsPath];

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

    return [iOSDevices valueForKey:deviceModel];
}

其他回答

我已经创建了plist文件,以帮助您获得每个设备的完整名称(源代码就在我的答案的末尾)

根据OhhMee的回答,你可以这样使用:

斯威夫特4.0

static func deviceName() -> String {

        var systemInfo = utsname()
        uname(&systemInfo)

        guard let iOSDeviceModelsPath = Bundle.main.path(forResource: "iOSDeviceModelMapping", ofType: "plist") else { return "" }
        guard let iOSDevices = NSDictionary(contentsOfFile: iOSDeviceModelsPath) else { return "" }

        let machineMirror = Mirror(reflecting: systemInfo.machine)
        let identifier = machineMirror.children.reduce("") { identifier, element in
            guard let value = element.value as? Int8, value != 0 else { return identifier }
            return identifier + String(UnicodeScalar(UInt8(value)))
        }

        return iOSDevices.value(forKey: identifier) as! String
    }

不要忘记在桥接头中添加#import <sys/utsname.h>。

Objective - C

#import <sys/utsname.h>

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

    NSString *iOSDeviceModelsPath = [[NSBundle mainBundle] pathForResource:@"iOSDeviceModelMapping" ofType:@"plist"];
    NSDictionary *iOSDevices = [NSDictionary dictionaryWithContentsOfFile:iOSDeviceModelsPath];

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

    return [iOSDevices valueForKey:deviceModel];
}

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。

用以下代码添加一个新文件,并简单地调用UIDevice。modelName包含迄今为止发布的所有型号,包括iPhone 13系列和Swift 5.0

        let identifier = machineMirror.children.reduce("") { identifier, element in
            guard let value = element.value as? Int8, value != 0 else { return identifier }
            return identifier + String(UnicodeScalar(UInt8(value)))
        }

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)

    @"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;
}

```
