有没有办法在Swift中获得设备型号名称(iPhone 4S, iPhone 5, iPhone 5S等)?

我知道有一个名为UIDevice.currentDevice()的属性。模型,但它只返回设备类型(iPod touch, iPhone, iPad, iPhone模拟器等)。

我也知道在Objective-C中使用以下方法可以轻松完成:

#import <sys/utsname.h>

struct utsname systemInfo;
uname(&systemInfo);

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

但是我正在Swift中开发我的iPhone应用程序,所以有人可以帮助我用等效的方法在Swift中解决这个问题吗?


当前回答

struct DeviceType {
        static let IS_IPHONE_4_OR_LESS = UIDevice.current.userInterfaceIdiom == .phone && Constants.SCREEN_MAX_LENGTH < 568
        static let IS_IPHONE_5 = UIDevice.current.userInterfaceIdiom == .phone && Constants.SCREEN_MAX_LENGTH == 568
        static let IS_IPHONE_6 = UIDevice.current.userInterfaceIdiom == .phone && Constants.SCREEN_MAX_LENGTH == 667
        static let IS_IPHONE_6P = UIDevice.current.userInterfaceIdiom == .phone && Constants.SCREEN_MAX_LENGTH == 736
        static let IS_IPAD = UIDevice.current.userInterfaceIdiom == .pad && Constants.SCREEN_MAX_LENGTH == 1024
    }

基于这个答案和这个答案。我创造了一个公共主旨

如何使用它

let boolean: Bool = UIDevice.isDevice(ofType: .iPhoneX)
// true or false

let specificDevice: DeviceModel.Model = UIDevice.modelType
// iPhone6s, iPhoneX, iPad etc...

let model: DeviceModel = UIDevice.model
// .simulator(let specificDevice), .real(let specificDevice),
// .unrecognizedSimulator(let string), .unrecognized(let string)

let modelName: String = UIDevice.model.name
// iPhone 6, iPhone X, etc...

这是要点里面的代码

public extension UIDevice {
    public static var modelCode: String {
        if let simulatorModelIdentifier = ProcessInfo().environment["SIMULATOR_MODEL_IDENTIFIER"] { return simulatorModelIdentifier }
        var systemInfo = utsname()
        uname(&systemInfo)
        return withUnsafeMutablePointer(to: &systemInfo.machine) {
            ptr in String(cString: UnsafeRawPointer(ptr).assumingMemoryBound(to: CChar.self))
        }
    }

    public static var model: DeviceModel {
        // Thanks https://stackoverflow.com/a/26962452/5928180
        var systemInfo = utsname()
        uname(&systemInfo)
        let modelCode = withUnsafeMutablePointer(to: &systemInfo.machine) {
            ptr in String(cString: UnsafeRawPointer(ptr).assumingMemoryBound(to: CChar.self))
        }

        // Thanks https://stackoverflow.com/a/33495869/5928180
        if modelCode == "i386" || modelCode == "x86_64" {
            if let simulatorModelCode = ProcessInfo().environment["SIMULATOR_MODEL_IDENTIFIER"], let model = DeviceModel.Model(modelCode: simulatorModelCode) {
                return DeviceModel.simulator(model)
            } else if let simulatorModelCode = ProcessInfo().environment["SIMULATOR_MODEL_IDENTIFIER"] {
                return DeviceModel.unrecognizedSimulator(simulatorModelCode)
            } else {
                return DeviceModel.unrecognized(modelCode)
            }
        } else if let model = DeviceModel.Model(modelCode: modelCode) {
            return DeviceModel.real(model)
        } else {
            return DeviceModel.unrecognized(modelCode)
        }
    }

    public static var modelType: DeviceModel.Model? {
        return UIDevice.model.model
    }

    public static func isDevice(ofType model: DeviceModel.Model) -> Bool {
        return UIDevice.modelType == model
    }

对于swift4.0及以上使用以下代码:

let udid = UIDevice.current.identifierForVendor?.uuidString
let name = UIDevice.current.name
let version = UIDevice.current.systemVersion
let modelName = UIDevice.current.model
let osName = UIDevice.current.systemName
let localized = UIDevice.current.localizedModel

print(udid ?? "")
print(name)
print(version)
print(modelName)
print(osName)
print(localized)

在Swift 3中是这样的

 UIDevice.current.model

斯威夫特5。X,设备和模拟器更新到2022年

(总是检查和更新!)

最后:iPhone 14所有版本,iPhone SE 2022年第三代,iPad Air第5代,iPhone 13(所有型号),iPad第9代2021年,iPad mini第6代2021年,Apple Watch Series 7, iPad Pro(11英寸)(第三代),iPad Pro(12.9英寸)(第5代)和Apple TV 4K(第二代),(更新也适用于所有ipod, Apple Watch和Apple TV)

即使是模拟器,该方法也能检测出正确的模型。(在模拟器中运行的模拟器设备模型的确切名称)

有了这个答案,由于枚举,您可以在几行中检查多个设备

例子:

var myDefaultFontSize: CGFloat = 26.0
switch UIDevice().type {
    case .iPhoneSE, .iPhone5, .iPhone5S: print("default value")
    case .iPhone6, .iPhone7, .iPhone8, .iPhone6S, .iPhoneX: myDefaultFontSize += 4
    default: break
}

这是代码:

//Simulator

用法: 您可以简单地获得设备模型:

let deviceType = UIDevice().type

或打印精确的字符串:

print("Running on: \(UIDevice().type)")
Output -> "iPhone X"

另一个关于case的例子:

var myDefaultHeight: CGFloat = 30.0
switch UIDevice().type {
    case .iPhoneSE, .iPhone5, .iPhone5S: print("default value")
    case .iPhone6, .iPhone7, .iPhone8, .iPhone6S, .iPhoneX: myDefaultHeight+= 5
    case .iPhone11, .iPhone12, .iPhone13: myDefaultHeight+= 10
    default: break
}
