推荐答案

NSUserDefaults非常易于使用和存储每个键只有一个值。但显然，它不是一种非常安全的方法，因为没有加密。

NSUserDefaults is quite easy to use and stores one value per key only. But apparently, it is not a very secure method, as there is no encryption.

但是Keychain是安全的，虽然它有点难以编码。
您可以参考这些链接以使用钥匙串访问。

But the Keychain is secure, though it is a bit hard to code. You can refer these link to use keychain access.
