Swift 4或更高版本

extension UIDevice {
    var modelName: String {
        if let modelName = ProcessInfo.processInfo.environment["SIMULATOR_MODEL_IDENTIFIER"] { return modelName }
        var info = utsname()
        uname(&info)
        return String(String.UnicodeScalarView(
                   Mirror(reflecting: info.machine)
                    .children
                    .compactMap {
                        guard let value = $0.value as? Int8 else { return nil }
                        let unicode = UnicodeScalar(UInt8(value))
                        return unicode.isASCII ? unicode : nil
                    }))
    }
}

UIDevice.current.modelName   // "iPad6,4"

对于那些不想使用Swift的Mirror的人，这里有一个使用普通类型的解决方案(也支持模拟器):

#if targetEnvironment(simulator)
@objc public protocol UIDevicePrivate {
    @objc func _deviceInfoForKey(_:String) -> Any?
}
#endif

extension UIDevice {
    var hardwareModel: String {
#if targetEnvironment(simulator)
        let privateSelf = unsafeBitCast(self, to:UIDevicePrivate.self)
        if let model = privateSelf._deviceInfoForKey("HWModelStr") as? String {
            return model + " (Simulator)"
        }
#endif
        var systemInfo = utsname()
        uname(&systemInfo)
        return String(characters: systemInfo.machine)
    }
}

如果你有一个plist设备(例如在https://stackoverflow.com/a/17655825/849616中由@Tib维护)来处理Swift 3，你会使用:

extension UIDevice {
    /// Fetches the information about the name of the device.
    ///
    /// - Returns: Should return meaningful device name, if not found will return device system code.
    public static func modelName() -> String {
        let physicalName = deviceSystemCode()
        if let deviceTypes = deviceTypes(), let modelName = deviceTypes[physicalName] as? String {
            return modelName
        }
        return physicalName
    }
}

private extension UIDevice {
    /// Fetches from system the code of the device
    static func deviceSystemCode() -> String {
        var systemInfo = utsname()
        uname(&systemInfo)
        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 identifier
    }

    /// Fetches the plist entries from plist maintained in https://stackoverflow.com/a/17655825/849616
    ///
    /// - Returns: A dictionary with pairs of deviceSystemCode <-> meaningfulDeviceName.
    static func deviceTypes() -> NSDictionary? {
        if let fileUrl = Bundle.main.url(forResource: "your plist name", withExtension: "plist"),
            let configurationDictionary = NSDictionary(contentsOf: fileUrl) {
            return configurationDictionary
        }
        return nil
    }
}

稍后您可以使用UIDevice.modelName()调用它。

额外的荣誉归于@Tib(用于plist)， @Aniruddh Joshi(用于deviceSystemCode()函数)。

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];
}

设备名称和机器名称，基于iOS真实设备硬件

我对这个问题的解决方案基本上看起来与这个帖子中的@NicolasMiari的答案有关。单独的实用程序类具有一组预定义的设备名和机器名，然后根据实际的机器名检索设备名。

注:此答案及其链接的GitHub项目已更新，以识别截至2017年10月的最新iPhone (iPhone 8, 8+， X)。这也适用于iOS11。请访问GitHub回购和看到，并给我反馈，如果有什么错误。

我已经在一个类中添加了这个实现和其他一些方便的实用工具方法，并把它放在这个GitHub存储库中。你也可以在这个Wiki页面中找到最新的设备信息列表。

请访问并使用它。

您可能需要导入sys框架，

#import <sys/utsname.h>
