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?

/// Obtain the machine hardware platform from the `uname()` unix command
///
/// Example of return values
/// - `"iPhone8,1"` = iPhone 6s
/// - `"iPad6,7"` = iPad Pro (12.9-inch)
static var unameMachine: String {
var utsnameInstance = utsname()
uname(&utsnameInstance)
let optionalString: String? = withUnsafePointer(to: &utsnameInstance.machine) {
$0.withMemoryRebound(to: CChar.self, capacity: 1) {
ptr in String.init(validatingUTF8: ptr)
}
}
return optionalString ?? "N/A"
}

还有另一个简单的替代方案(模型标识符参考可在https://www.theiphonewiki.com/wiki/Models):找到)
Swift 3/4/5的更新答案，包括字符串修剪和模拟器支持:
func modelIdentifier() -> String {
if let simulatorModelIdentifier = ProcessInfo().environment["SIMULATOR_MODEL_IDENTIFIER"] { return simulatorModelIdentifier }
var sysinfo = utsname()
uname(&sysinfo) // ignore return value
return String(bytes: Data(bytes: &sysinfo.machine, count: Int(_SYS_NAMELEN)), encoding: .ascii)!.trimmingCharacters(in: .controlCharacters)
}
使用Swift 3 (Xcode 8.3)
func deviceName() -> String {
var systemInfo = utsname()
uname(&systemInfo)
let str = withUnsafePointer(to: &systemInfo.machine.0) { ptr in
return String(cString: ptr)
}
return str
}
注意:根据官方开发论坛的回答，以这种方式使用元组是安全的。大Int8元组的内存对齐方式将与大Int8数组相同。即:连续且无填充。
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)
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
}

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。
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
}
