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
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

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))

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
}

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
}
苹果设备型号请访问: https://www.theiphonewiki.com/wiki/Models
附注:我在这里做了一个新的异步实验(直接连接到THEIPHONEWIKI站点，源代码中没有很长的静态设备列表。
我已经实现了一个超轻量级的库，可以根据给出的一些答案来检测使用的设备:https://github.com/schickling/Device.swift
它可以通过迦太基安装，并像这样使用:
import Device
let deviceType = UIDevice.currentDevice().deviceType
switch deviceType {
case .IPhone6: print("Do stuff for iPhone6")
case .IPadMini: print("Do stuff for iPad mini")
default: print("Check other available cases of DeviceType")
}
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
