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?

获取模型名称(营销名称)的最简单方法
小心使用私有API -[UIDevice _deviceinfokey:]，你不会被Apple拒绝。
// works on both simulators and real devices, iOS 8 to iOS 12
NSString *deviceModelName(void) {
// For Simulator
NSString *modelName = NSProcessInfo.processInfo.environment[@"SIMULATOR_DEVICE_NAME"];
if (modelName.length > 0) {
return modelName;
}
// For real devices and simulators, except simulators running on iOS 8.x
UIDevice *device = [UIDevice currentDevice];
NSString *selName = [NSString stringWithFormat:@"_%@ForKey:", @"deviceInfo"];
SEL selector = NSSelectorFromString(selName);
if ([device respondsToSelector:selector]) {
#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Warc-performSelector-leaks"
modelName = [device performSelector:selector withObject:@"marketing-name"];
#pragma clang diagnostic pop
}
return modelName;
}
我是怎么得到"marketing-name"这个密钥的?
运行在模拟器上的NSProcessInfo.processInfo.environment包含一个名为“SIMULATOR_CAPABILITIES”的键，其值是一个plist文件。然后你打开plist文件，你会得到模型名称的关键字“marketing-name”。

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

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()
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 {

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)
下面是模型参考:
https://theiphonewiki.com/wiki/Models https://theiphonewiki.com/wiki/BORD
这个Swift 3.0示例将当前设备模型作为枚举常量返回(以避免与字符串字面值直接比较)。enum的原始值是一个包含人类可读的iOS设备名称的字符串。因为它是Swift，所以认可的设备列表只包括最新的机型，足以支持包含Swift的iOS版本。下面的使用示例利用了这个答案末尾的实现:
switch UIDevice().type {
case .iPhone5:
print("No TouchID sensor")
case .iPhone5S:
fallthrough
case .iPhone6:
fallthrough
case .iPhone6plus:
fallthrough
case .iPad_Pro9_7:
fallthrough
case .iPad_Pro12_9:
fallthrough
case .iPhone7:
fallthrough
case .iPhone7plus:
print("Put your thumb on the " +
UIDevice().type.rawValue + " TouchID sensor")
case .unrecognized:
print("Device model unrecognized");
default:
print(UIDevice().type.rawValue + " not supported by this app");
}
你的应用应该保持最新的新设备发布，以及当苹果为同一设备家族添加新型号时。例如，iPhone3、1 iPhone3、2 iPhone3、4都是“iPhone 4”。避免编写不考虑新型号的代码，这样你的算法就不会意外地配置失败或对新设备做出响应。你可以参考这个维护列表的iOS设备型号#更新你的应用程序在战略时刻。
iOS includes device-independent interfaces to detect hardware capabilities and parameters such as screen size. The generalized interfaces Apple provides are usually the safest, best supported mechanisms to dynamically adapt an app's behavior to different hardware. Nevertheless, the following code can be useful for prototyping, debugging, testing, or any time code needs to target a specific device family. This technique can also be useful to describe the current device by its common/publicly recognized name.

uname(&sysinfo) // ignore return value
return String(bytes: Data(bytes: &sysinfo.machine, count: Int(_SYS_NAMELEN)), encoding: .ascii)!.trimmingCharacters(in: .controlCharacters)
