問題描述

如何在 iPhone 應用程序上存儲多個帳戶的用戶登錄詳細信息（用戶、密碼） (How to store user Login details(user, pass) for multiple accounts on iPhone app)

我有一個要求用戶登錄（用戶名、密碼）的 iPhone 應用程序。我目前存儲上次成功登錄的憑據，並在用戶下次啟動應用程序時填寫文本字段。

很多時候，雖然用戶可能擁有多個帳戶，但我現在需要實現一些東西存儲更多帳戶的登錄憑據。

您如何建議我這樣做？我環顧四周，但找不到與此相關的任何內容。

參考解法

方法 1:

NSUserDefaults or Storing into sqllite or Storing into a plist are on of the ways of storing persistent data. But they are not secure. I will recommend Key Chain Access for storing secure data.

This link provides a apple sample code which uses key chain Access

http://developer.apple.com/library/ios/#samplecode/GenericKeychain/Introduction/Intro.html#//apple_ref/doc/uid/DTS40007797‑Intro‑DontLinkElementID_2

But one disadvantage is you cant test this in simulator it works only on device i think.

You can also add multiple items to the keychain.

方法 2:

Look NSUserDefaults at the documentation.

Maybe this tuto can help you : http://icodeblog.com/2008/10/03/iphone‑programming‑tutorial‑savingretrieving‑data‑using‑nsuserdefaults/

方法 3:

Try with CoreData...
