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!


当前回答

不使用镜像也可以在Swift中获取设备名称。Swift可以在需要的地方自动将内容转换为指针。其实很简单:

/// Returns "iPhone1,1", etc.
var deviceName: String {
    var sysinfo = utsname()
    uname(&sysinfo)
    return String(cString: &sysinfo.machine.0)
}

虽然这个问题在2012年就被提出了,但苹果仍然没有给出将设备模式标识符转换为设备名称的方法。 有很多答案依赖于硬编码这些名称,不幸的是,当苹果发布新设备时,这些名称很快就过时了。

我们需要的是一种方法来获得一个不断更新的列表,它就在这里:https://github.com/ptrkstr/Devices

每次添加新设备时,这个Swift包都会更新,你所需要做的就是更新你的依赖项来获得它们。

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];
}

        ]

        if model!.characters.count > 0 {
            myDeviceName = deviceNamesByCode[model!]!
        }else{
            myDeviceName = UIDevice.currentDevice().model
        }

        print("myDeviceName==\(myDeviceName)")
        return myDeviceName

    }

[[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

import UIKit
import SystemConfiguration

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)))
        }
        
        let deviceMapping = ["i386": "iPhone Simulator",
         "x86_64": "iPhone Simulator",
         "arm64": "iPhone Simulator",
         "iPhone1,1": "iPhone",
         "iPhone1,2": "iPhone 3G",
         "iPhone2,1": "iPhone 3GS",
         "iPhone3,1": "iPhone 4",
