{
    [super viewDidLoad];
    struct utsname systemInfo;
    uname(&systemInfo);
    NSLog(@"hardware: %@",[HARDWARE objectForKey:[NSString stringWithCString: systemInfo.machine encoding:NSUTF8StringEncoding]]);
}

以下是Aniruddh基于uname的方法的现代版本，它不依赖于Mirror，应该适用于Swift 4.2及更高版本:

import UIKit

extension UIDevice {
  var machineName: String {
    var info = utsname()
    return withUnsafeMutablePointer(to: &info) { info in
      // We could alternatively return nil here, or handle
      // errors some other way.
      guard uname(info) == 0 else { return model }
      let offset = MemoryLayout.offset(of: \utsname.machine)!
      let machine = UnsafeRawPointer(info).advanced(by: offset).assumingMemoryBound(to: CChar.self)
      return String(cString: machine)
    }
  }
}

一个从NSString描述中脱离的类别

通常，在整个代码中避免任意的字符串比较是可取的。最好在一个地方更新字符串，并在应用程序中隐藏神奇的字符串。为此，我在UIDevice上提供了一个类别。

对于我的特定需求，我需要知道我正在使用的设备，而不需要知道可以通过其他方式轻松检索的网络功能的细节。因此，您将发现一个比不断增长的设备列表更粗粒度的枚举。

更新就是将设备添加到枚举和查找表中。

[[UIDevice currentDevice] model]只返回iPhone或iPod，你不会得到能让你区分不同代设备的型号的数字。

编写这个方法:

#include <sys/sysctl.h>
...

+ (NSString *)getModel {
    size_t size;
    sysctlbyname("hw.machine", NULL, &size, NULL, 0);
    char *model = malloc(size);
    sysctlbyname("hw.machine", model, &size, NULL, 0);
    NSString *deviceModel = [NSString stringWithCString:model encoding:NSUTF8StringEncoding];
    free(model);
    return deviceModel;
}

当你需要模型的时候调用方法[self getModel]，你会得到例如:"iPhone5,1"对于超薄而快速的iPhone5。

一个好的做法是创建一个名为Utils.h/Utils的类。m并在那里放置像getModel这样的方法，这样你就可以从应用程序的任何地方获得这些信息，只需导入类并调用[Utils getModel];

用以下代码添加一个新文件，并简单地调用UIDevice。modelName包含迄今为止发布的所有型号，包括iPhone 13系列和Swift 5.0

    static let modelName: String = {

        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)))
        }

使用ideviceinfo获取这些值怎么样?应该能够安装它使用brew安装ideviceinfo

然后运行:

PRODUCT_NAME=$(ideviceinfo --udid $DEVICE_UDID --key ProductName)
PRODUCT_TYPE=$(ideviceinfo --udid $DEVICE_UDID --key ProductType)
PRODUCT_VERSION=$(ideviceinfo --udid $DEVICE_UDID --key ProductVersion)
