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

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"
            case "iPhone4,1":                                     return "iPhone 4s"
            case "iPhone5,1", "iPhone5,2":                        return "iPhone 5"

            #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)

其他回答

如果你不想每次苹果向设备家族添加新型号时都更新你的代码,可以使用下面的方法只返回型号代码。

func platform() -> String {
        var systemInfo = utsname()
        uname(&systemInfo)
        let modelCode = withUnsafeMutablePointer(&systemInfo.machine) {
            ptr in String.fromCString(UnsafePointer<CChar>(ptr))
        }

        return String.fromCString(modelCode!)!
}

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()

以下是2023年1月更新的解决方案。包括最新的iPhone、iPad、Watch、iPod、Apple TV和HomePod:

extension UIDevice {
    
    static var 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)))
        }

}

用法:

UIDevice.modelName

这是一个用于检测apple设备的新库

import DeviceDetector

let detector = DeviceDetector.shared
let deviceName = detector.currentDeviceName
let deviceSet = detector.currentDevice
        
let information = """
Model: \(deviceName)
iPhone?: \(detector.isiPhone)
iPad?: \(detector.isiPad)
Notch?: \(detector.hasSafeArea)
        
4inch?: \(DeviceSet.iPhone4inchSet.contains(deviceSet))
4.7inch?: \(DeviceSet.iPhone4_7inchSet.contains(deviceSet))
iPhoneSE?: \(DeviceSet.iPhoneSESet.contains(deviceSet))
iPhonePlus?: \(DeviceSet.iPhonePlusSet.contains(deviceSet))
iPadPro?: \(DeviceSet.iPadProSet.contains(deviceSet))
"""

结果

我发现很多答案都用了字符串。我决定改变@HAS答案使用一个enum:

public enum Devices: String {
    case IPodTouch5
    case IPodTouch6
    case IPhone4
    case IPhone4S
    case IPhone5
    case IPhone5C
    case IPhone5S
    case IPhone6
    case IPhone6Plus
    case IPhone6S
    case IPhone6SPlus
    case IPhone7
    case IPhone7Plus
    case IPhoneSE
    case IPad2
    case IPad3
    case IPad4
    case IPadAir
    case IPadAir2
    case IPadMini
    case IPadMini2
    case IPadMini3
    case IPadMini4
    case IPadPro
    case AppleTV
    case Simulator
    case Other
}

public extension UIDevice {

    public var modelName: Devices {
        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)))
        }

        switch identifier {
