有没有办法在 Swift 中获取设备型号名称(iPhone 4S、iPhone 5、iPhone 5S 等)?
我知道有一个名为 UIDevice.currentDevice().model 的属性,但它只返回设备类型(iPod touch、iPhone、iPad、iPhone 模拟器等)。
我也知道它可以在 Objective-C 中使用这种方法轻松完成:
#import <sys/utsname.h>
struct utsname systemInfo;
uname(&systemInfo);
NSString* deviceModel = [NSString stringWithCString:systemInfo.machine
encoding:NSUTF8StringEncoding];
但是我正在用 Swift 开发我的 iPhone 应用程序,所以有人可以用等效的方法帮助我在 Swift 中解决这个问题吗?
最佳答案
我在 UIDevice 上做了这个“纯 Swift”扩展.
如果您正在寻找更优雅的解决方案,您可以使用 my µ-framework DeviceKit发布在 GitHub 上(也可通过 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 {

你可以这样调用它:
let modelName = UIDevice.modelName
对于真实设备,它返回例如“iPad Pro(12.9 英寸)(第 5 代)”,对于模拟器,它返回例如《模拟器 iPad Pro(12.9 英寸)(第 5 代)》
