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。
