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?

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)
import UIKit
public extension UIDevice {
/// pares the deveice name as the standard name
var modelName: String {
#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
switch identifier {

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()

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()

UIDevice.hardwareModel // → iPhone9,3
斯威夫特3.1
我对简单地调用utsname的看法是:
func platform() -> String {
var systemInfo = utsname()
uname(&systemInfo)
let size = Int(_SYS_NAMELEN) // is 32, but posix AND its init is 256....
let s = withUnsafeMutablePointer(to: &systemInfo.machine) {p in
p.withMemoryRebound(to: CChar.self, capacity: size, {p2 in
return String(cString: p2)
})
}
return s
}
和其他的一样，但对C/Swift和后面的复杂结构更清晰一些。 )：
返回值如"x86_64"
