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?

维基设备
异步库，从iphonewiki给你答案
A crazy little experiment for automation fans like me. I made this algorithm that reads the identification code of the device, physical or simulated, and load the theiphonewiki page to extrapolate the model name based on the identification code (example iPhone11,2 -> iPhone XS). The algorithm interfaces with the WIKI page using the internal Wiki API Sandbox tool that allows you to have a JSON response, however the content is not obtainable in JSON (just the part that was needed, that is the wikitables) so I parsed the HTML content to get to the device name, without using third parts HTML parsing libraries.
优点:总是更新，你不需要添加新的设备
缺点:异步回答使用维基页面从网络
附注:请随意改进我的代码，以获得更精确的结果和更优雅的语法 P.S.S.如果你需要更直接的答案，请使用我之前在本页的答案

用法:
var deviceModel:String = ""
WikiDevice.model { (model) in
print("Using WikiDevice, running on: \(model)")
deviceModel = model
}
输出:
Using WikiDevice, running on: iPhone 11 Pro Max

当你使用Swift 3时，接受的答案有一些问题! 这个答案(灵感来自NAZIK)适用于Swift 3和新款iPhone:
import UIKit
public extension UIDevice {
var modelName: String {
#if (arch(i386) || arch(x86_64)) && os(iOS)
let DEVICE_IS_SIMULATOR = true
#else
let DEVICE_IS_SIMULATOR = false
#endif
var machineString = String()
if DEVICE_IS_SIMULATOR == true
{
if let dir = ProcessInfo().environment["SIMULATOR_MODEL_IDENTIFIER"] {
machineString = dir
}
}
else {
var systemInfo = utsname()
uname(&systemInfo)
let machineMirror = Mirror(reflecting: systemInfo.machine)
machineString = 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 machineString {
case "iPod4,1": return "iPod Touch 4G"
case "iPod5,1": return "iPod Touch 5G"
case "iPod7,1": return "iPod Touch 6G"
case "iPhone3,1", "iPhone3,2", "iPhone3,3": return "iPhone 4"

}
}
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
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 {
case "iPod5,1": return Devices.IPodTouch5
case "iPod7,1": return Devices.IPodTouch6
case "iPhone3,1", "iPhone3,2", "iPhone3,3": return Devices.IPhone4
case "iPhone4,1": return Devices.IPhone4S

}
我在UIDevice上做了另一个示例扩展，包括基于@HAS的答案的模拟器模型标识符。它在上面的Swift3.2(包括Swift 4)中工作得很好。x, Swift 5):
let modelName = UIDevice.current.modelName
新增型号:iPod touch(第七代)，iPhone SE(第二代)，iPhone 12 mini, iPhone 12 Pro, iPhone 12 Pro Max, iPad Pro(12.9英寸)(第四代)

public extension UIDevice {
/// pares the deveice name as the standard name

#if targetEnvironment(simulator)
let identifier = ProcessInfo().environment["SIMULATOR_MODEL_IDENTIFIER"]!
#else
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)))
}
#endif

}
}
Swift 3.0或更高版本
import UIKit
class ViewController: UIViewController {
let device = UIDevice.current
override func viewDidLoad() {
super.viewDidLoad()
let model = device.model
print(model) // e.g. "iPhone"
let modelName = device.modelName
print(modelName) // e.g. "iPhone 6" /* see the extension */
let deviceName = device.name
print(deviceName) // e.g. "My iPhone"
let systemName = device.systemName
print(systemName) // e.g. "iOS"
let systemVersion = device.systemVersion
print(systemVersion) // e.g. "10.3.2"
if let identifierForVendor = device.identifierForVendor {
print(identifierForVendor) // e.g. "E1X2XX34-5X6X-7890-123X-XXX456C78901"
}
}
}
并添加以下扩展
extension UIDevice {
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)))
}
switch identifier {
case "iPod5,1": return "iPod Touch 5"
case "iPod7,1": return "iPod Touch 6"
case "iPhone3,1", "iPhone3,2", "iPhone3,3": return "iPhone 4"
case "iPhone4,1": return "iPhone 4s"
case "iPhone5,1", "iPhone5,2": return "iPhone 5"
