iOS开发中用什么替代UDID

查了下资料,有的使用的是UUID,但是UUID,每次把应用删除以后,以前的信息不能保留,网上推荐的做法,是UUID加上钥匙串.

这里想问下,大家实际开发中用的是什么方案.

最后,谢谢大家

Answer 1

At present, there is no more effective method than UUID+keychain. The keychain can also be cleared after jailbreak, making it basically difficult to locate the same device.

Answer 2

You can use ad id
