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)
    }
}

typealias StaticArray256<Element> = (Element, Element, Element,Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element, Element)

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。

下面是它的代码(代码可能不包含所有设备的字符串，我和其他人在GitHub上维护相同的代码，所以请从那里获取最新的代码)

Objective-C: GitHub/DeviceUtil

吉hub /恶魔大师

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

- (NSString*)hardwareDescription {
    NSString *hardware = [self hardwareString];
    if ([hardware isEqualToString:@"iPhone1,1"]) return @"iPhone 2G";
    if ([hardware isEqualToString:@"iPhone1,2"]) return @"iPhone 3G";
    if ([hardware isEqualToString:@"iPhone3,1"]) return @"iPhone 4";
    if ([hardware isEqualToString:@"iPhone4,1"]) return @"iPhone 4S";
    if ([hardware isEqualToString:@"iPhone5,1"]) return @"iPhone 5";
    if ([hardware isEqualToString:@"iPod1,1"]) return @"iPodTouch 1G";
    if ([hardware isEqualToString:@"iPod2,1"]) return @"iPodTouch 2G";
    if ([hardware isEqualToString:@"iPad1,1"]) return @"iPad";
    if ([hardware isEqualToString:@"iPad2,6"]) return @"iPad Mini";
    if ([hardware isEqualToString:@"iPad4,1"]) return @"iPad Air WIFI";
    //there are lots of other strings too, checkout the github repo
    //link is given at the top of this answer

    if ([hardware isEqualToString:@"i386"]) return @"Simulator";
    if ([hardware isEqualToString:@"x86_64"]) return @"Simulator";

    return nil;
}

- (NSString*)hardwareString {
    size_t size = 100;
    char *hw_machine = malloc(size);
    int name[] = {CTL_HW,HW_MACHINE};
    sysctl(name, 2, hw_machine, &size, NULL, 0);
    NSString *hardware = [NSString stringWithUTF8String:hw_machine];
    free(hw_machine);
    return hardware;
}

你可以试试这个库:http://github.com/erica/uidevice-extension/(作者Erica Sadun)。(图书馆有7-8年的历史，已经过时了)

(示例代码):

    [[UIDevice currentDevice] platformType]   // ex: UIDevice4GiPhone
    [[UIDevice currentDevice] platformString] // ex: @"iPhone 4G"

或者你可以用这个方法:

您可以使用sys/utsname.h中的uname获取设备型号。例如:

objective - c

    #import <sys/utsname.h> // import it in your header or implementation file.

    NSString* deviceName()
    {
        struct utsname systemInfo;
        uname(&systemInfo);
    
        return [NSString stringWithCString:systemInfo.machine
                                  encoding:NSUTF8StringEncoding];
    }

斯威夫特3

    extension UIDevice {
        var 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)))
            }
            return identifier
        }
    }

    print(UIDevice.current.modelName)
