推荐答案

因此，如果您不关心新的AppStore规则等...，请继续:

So, if you don't care about the new AppStore rules etc... here you go:

- (NSString *)getSystemUUID {
    io_service_t platformExpert = IOServiceGetMatchingService(kIOMasterPortDefault,IOServiceMatching("IOPlatformExpertDevice"));
    if (!platformExpert)
        return nil;

    CFTypeRef serialNumberAsCFString = IORegistryEntryCreateCFProperty(platformExpert,CFSTR(kIOPlatformUUIDKey),kCFAllocatorDefault, 0);
    IOObjectRelease(platformExpert);
    if (!serialNumberAsCFString)
        return nil;

    return (__bridge NSString *)(serialNumberAsCFString);;
}

请注意:

• 为此，您需要将IOKit.framework添加到您的项目中 去工作.
• 此代码符合ARC；
• 此代码是安全的，如果出现问题，它将返回nil NSString；
• Apple不保证所有将来的系统都将具有软件可读的序列号.
• 开发人员不应对 序列号的格式，例如长度或字符 可能包含.

• You need to add IOKit.framework to your project in order for this to work.
• This code is ARC compliant;
• This code is safe and it will return a nil NSString if something goes wrong;
• Apple does not guarantee that all future systems will have a software-readable serial number.
• Developers should not make any assumptions about the format of the serial number such as its length or what characters it may contain.
