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

对我有用

var sysinfo = utsname()
uname(&sysinfo)
let data = Data(bytes: &sysinfo.machine, count: Int(_SYS_NAMELEN))
let model = String(cString: [UInt8](data) //iPhone13,1

其他回答

在swift中处理c结构体是很痛苦的。尤其是当里面有c数组的时候。以下是我的解决方案:继续使用objective-c。只需创建一个包装器objective-c类来完成这项工作,然后在swift中使用该类。下面是一个示例类,它就是这样做的:

@interface DeviceInfo : NSObject

+ (NSString *)model;

@end

#import "DeviceInfo.h"
#import <sys/utsname.h>

@implementation DeviceInfo

+ (NSString *)model
{
    struct utsname systemInfo;
    uname(&systemInfo);

    return [NSString stringWithCString: systemInfo.machine encoding: NSUTF8StringEncoding];
}

@end

在迅捷的一面:

let deviceModel = DeviceInfo.model()

我在UIDevice上做了这个“纯Swift”扩展。

如果你正在寻找一个更优雅的解决方案,你可以使用我在GitHub上发布的µ-框架DeviceKit(也可以通过CocoaPods, Carthage和Swift Package Manager获得)。

代码如下:

import UIKit

public extension UIDevice {

    static let modelName: 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)))
        }

        func mapToDevice(identifier: String) -> String { // swiftlint:disable:this cyclomatic_complexity
            #if os(iOS)
            switch identifier {
            case "iPod5,1":                                       return "iPod touch (5th generation)"
            case "iPod7,1":                                       return "iPod touch (6th generation)"
            case "iPod9,1":                                       return "iPod touch (7th generation)"
            case "iPhone3,1", "iPhone3,2", "iPhone3,3":           return "iPhone 4"

            #endif
        }

        return mapToDevice(identifier: identifier)
    }()

}

你这样称呼它:

let modelName = UIDevice.modelName

对于真实的设备,它返回例如:“iPad Pro(12.9英寸)(第五代)”,对于模拟器,它返回例如。模拟式iPad Pro(12.9英寸)(第五代)

下面是模型参考:

https://theiphonewiki.com/wiki/Models https://theiphonewiki.com/wiki/BORD

extension UIDevice {

    public static let hardwareModel: String = {
        var path = [CTL_HW, HW_MACHINE]
        var n = 0
        sysctl(&path, 2, nil, &n, nil, 0)
        var a: [UInt8] = .init(repeating: 0, count: n)
        sysctl(&path, 2, &a, &n, nil, 0)
        return .init(cString: a)
    }()
}

UIDevice.hardwareModel // → iPhone9,3

对我有用

var sysinfo = utsname()
uname(&sysinfo)
let data = Data(bytes: &sysinfo.machine, count: Int(_SYS_NAMELEN))
let model = String(cString: [UInt8](data) //iPhone13,1

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()
