如何删除 UIWebView 的所有 cookie?

How to delete all cookies of UIWebView?(如何删除 UIWebView 的所有 cookie?)

问题描述

在我的应用程序中，我有一个 UIWebview 加载linkedin 身份验证页面以进行登录.当用户登录时，cookies 会保存到应用程序中.

In my application, I have a UIWebview that loads linkedin auth page for login. When user logs in, cookies saves into the application.

我的应用有一个与linkedin 登录无关的注销按钮.因此，当用户单击此按钮时，他会从应用程序中注销.我希望这次注销也会从应用程序中清除他的linkedin cookie，以便用户完全注销.

My app has a logout button that is not related to linkedin login. So when user clicks on this button, he logs off from the app. I want that this log off will clear his linkedin cookies also from the app, so that user will log out completely.
