如何在iOS上获得设备制作和模型?

I was wondering if it's possible to determine what kind of iPhone (for example) the currentdevice is? I know it's possible to get the model through NSString *deviceType = [[UIDevice currentDevice] model]; which will just return whether I have an "iPhone" or an "iPod", BUT I was wondering if it's possible to detect/know if I have an iPhone 3GS vs. and iPhone 4 vs. an iPhone 4S (in actuality, all I really want to do is determine if I have a 3G or not, because I'm doing fairly graphics intensive stuff).

所以，请告诉我，谢谢!

memScoped {
            val q = alloc<utsname>()
            uname(q.ptr)
            val identifier = NSString.stringWithCString(q.machine, encoding = NSUTF8StringEncoding)
        }

我已经创建了plist文件，以帮助您获得每个设备的完整名称(源代码就在我的答案的末尾)

根据OhhMee的回答，你可以这样使用:

斯威夫特4.0

static func deviceName() -> String {

        var systemInfo = utsname()
        uname(&systemInfo)

        guard let iOSDeviceModelsPath = Bundle.main.path(forResource: "iOSDeviceModelMapping", ofType: "plist") else { return "" }
        guard let iOSDevices = NSDictionary(contentsOfFile: iOSDeviceModelsPath) else { return "" }

        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)))
        }

        return iOSDevices.value(forKey: identifier) as! String
    }

不要忘记在桥接头中添加#import <sys/utsname.h>。

Objective - C

#import <sys/utsname.h>

NSString *machineName()
{
    struct utsname systemInfo;
    uname(&systemInfo);

    NSString *iOSDeviceModelsPath = [[NSBundle mainBundle] pathForResource:@"iOSDeviceModelMapping" ofType:@"plist"];
    NSDictionary *iOSDevices = [NSDictionary dictionaryWithContentsOfFile:iOSDeviceModelsPath];

    NSString* deviceModel = [NSString stringWithCString:systemInfo.machine
                                               encoding:NSUTF8StringEncoding];

    return [iOSDevices valueForKey:deviceModel];
}

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)
    }
  }
}

[[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];

在Swift的iOS7或更高版本上完全正常工作

func DeviceName()-> String {

        var myDeviceName : String = String()

        var systemInfo = [UInt8](count: sizeof(utsname), repeatedValue: 0)

        let model = systemInfo.withUnsafeMutableBufferPointer { (inout body: UnsafeMutableBufferPointer<UInt8>) -> String? in

            if uname(UnsafeMutablePointer(body.baseAddress)) != 0 {
                return nil
            }

            return String.fromCString(UnsafePointer(body.baseAddress.advancedBy(Int(_SYS_NAMELEN * 4))))
        }

        let deviceNamesByCode : [String: String] = ["iPod1,1":"iPod Touch 1",
