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!

UIDevice.current.modelName   // "iPad6,4"

设备名称和机器名称,基于iOS真实设备硬件

我对这个问题的解决方案基本上看起来与这个帖子中的@NicolasMiari的答案有关。单独的实用程序类具有一组预定义的设备名和机器名,然后根据实际的机器名检索设备名。

注:此答案及其链接的GitHub项目已更新,以识别截至2017年10月的最新iPhone (iPhone 8, 8+, X)。这也适用于iOS11。请访问GitHub回购和看到,并给我反馈,如果有什么错误。

我已经在一个类中添加了这个实现和其他一些方便的实用工具方法,并把它放在这个GitHub存储库中。你也可以在这个Wiki页面中找到最新的设备信息列表。

请访问并使用它。

更新:

您可能需要导入sys框架,

#import <sys/utsname.h>

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];
}

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)
}

(向这个被低估的答案致敬https://stackoverflow.com/a/43599474/843454)

对于那些不想使用Swift的Mirror的人,这里有一个使用普通类型的解决方案(也支持模拟器):

#if targetEnvironment(simulator)
@objc public protocol UIDevicePrivate {
    @objc func _deviceInfoForKey(_:String) -> Any?
}
#endif

extension UIDevice {
    var hardwareModel: String {
#if targetEnvironment(simulator)
        let privateSelf = unsafeBitCast(self, to:UIDevicePrivate.self)
        if let model = privateSelf._deviceInfoForKey("HWModelStr") as? String {
            return model + " (Simulator)"
        }
#endif
        var systemInfo = utsname()
        uname(&systemInfo)
        return String(characters: systemInfo.machine)
    }
}
