iPhone上的应用程序设置的安全性如何？

Question

It appears that each app has access to its own config settings, which could be kept after app be shutdown. I am wondering whether one app's config setting could be accessed from other app.

Should I save sensitive data like password to the app config?

Is there some better way?

Answer 1

钥匙串是应保存密码或其他敏感信息的位置。

Buzz Andersen的代码可以在模拟器和iPhone上正确获取和设置Keychain密码： SFHFKeychainUtils 。
