iOS-正在保存当前用户-钥匙串和保存到磁盘是否互斥？

Question

I want to save a current user of my application, but I'm a bit confused on how I choose between what's necessary for the keychain and what should be saved to disk or even if both or just one should be used.

I'm thinking I should save the user's email and password to keychain, then save the user object (comprised of email, password, name, gender, and uuid) to disk (minus the email and password)

Is this the correct approach? Or should I be doing something else

Answer 1

In your case, the data you wish to store is tiny: why not store it all in the keychain? It won't be more effort, and will in the end prove simpler than storing half on disk and half in the keychain. And if the user has keychain sync activated, you benefit from that for free...
