iphone - 他们是UDID的替代品吗？

Question

由于 UDID 已被弃用，他们有任何替代 UDID 的方法吗？

Answer 1

You can use the following thing as a unique Identifier for your app user's :

I use the method below to create a UUID and save it to the user preferences the first time the app is started:

- (NSString *)getUUID
{
    NSString *UUID = [[NSUserDefaults standardUserDefaults] objectForKey:@"uniqueID"];
    if (!UUID)
    {
        CFUUIDRef theUUID = CFUUIDCreate(NULL);
        CFStringRef string = CFUUIDCreateString(NULL, theUUID);
        CFRelease(theUUID);
        UUID = [(__bridge NSString*)string stringByReplacingOccurrencesOfString:@"-"withString:@""];
        [[NSUserDefaults standardUserDefaults] setValue:UUID forKey:@"uniqueID"];
    }
    return UUID;
}

Hope that helps !

Apple 停止支持 iOS 的唯一标识符。这个源代码解决了这个问题。它根据设备的mac地址和bundle标识符生成一个唯一标识符。
