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!

其他回答

[[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];

扩展OhhMee上面的回答,我添加了一些故障保险,以支持未来未列入列表的设备:

#import <sys/utsname.h>
#import "MyClass.h"

@implementation MyClass
{
    //(your private ivars)
}

- (NSString*) deviceName
{
    struct utsname systemInfo;

    uname(&systemInfo);

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

编辑:这个答案使用Swift 2提供了类似的实现。

编辑2:我刚刚添加了iPad Pro型号(两种尺寸)。型号等供日后参考。可以在iPhone Wiki中找到。

编辑3:增加对iPhone XS、iPhone XS Max和iPhone XR的支持。

编辑4:增加对iPhone 11、iPhone 11 Pro和iPhone 11 Pro Max的支持。

如果你有一个plist设备(例如在https://stackoverflow.com/a/17655825/849616中由@Tib维护)来处理Swift 3,你会使用:

extension UIDevice {
    /// Fetches the information about the name of the device.
    ///
    /// - Returns: Should return meaningful device name, if not found will return device system code.
    public static func modelName() -> String {
        let physicalName = deviceSystemCode()
        if let deviceTypes = deviceTypes(), let modelName = deviceTypes[physicalName] as? String {
            return modelName
        }
        return physicalName
    }
}

private extension UIDevice {
    /// Fetches from system the code of the device
    static func deviceSystemCode() -> 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
    }

    /// Fetches the plist entries from plist maintained in https://stackoverflow.com/a/17655825/849616
    ///
    /// - Returns: A dictionary with pairs of deviceSystemCode <-> meaningfulDeviceName.
    static func deviceTypes() -> NSDictionary? {
        if let fileUrl = Bundle.main.url(forResource: "your plist name", withExtension: "plist"),
            let configurationDictionary = NSDictionary(contentsOf: fileUrl) {
            return configurationDictionary
        }
        return nil
    }
}

稍后您可以使用UIDevice.modelName()调用它。

额外的荣誉归于@Tib(用于plist), @Aniruddh Joshi(用于deviceSystemCode()函数)。
