从UIWebView清除凭据

问题描述：

我在这里做的是，获取具有身份验证的URL。因此，我使用函数

What i am doing here is, fetching a URL which has authentication. Hence, i use the function

  - (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge;

当面对身份验证时，我会提供一个UIAlertView来输入用户名和密码，如果用户输入了正确地说，这个方法被调用。

When it faces authentication, i present a UIAlertView to enter the username and password and if user has entered it correctly, this method is called.

  - (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response;

在此方法中，我使登录窗口消失并引入详细视图。

in this method, i make the login window disappear and bring in the detail view.

问题出现，当我想要退出功能时。我想要的是删除用户输入的凭据并再次获取该URL，以进行身份验证=目的。所以，我称之为 didReceiveAuthenticationChallenge 。

Problem arose, when i wanted a logout functionality. All i want is to remove the credentials entered by the user and fetch that URL again, for authentication= purpose. So, i call the didReceiveAuthenticationChallenge.

但是，它会直接转到 didReceiveResponse 方法，而不会询问任何内容。这里的问题是我无法清除凭据。你可以帮我这么做吗？

But what happens is it directly goes to the didReceiveResponse method without asking anything. The problem here is that i am not able to clear the credentials. Can you help me in doing this?

提前多多谢谢！

尝试使用代码清除Cookie请求

Try Code for Clear cookie of Request

NSHTTPCookie *cookie;
NSHTTPCookieStorage *storage = [NSHTTPCookieStorage sharedHTTPCookieStorage];
for (cookie in [storage cookies])
{
    NSString* domainName = [cookie domain];
    NSRange domainRange = [domainName rangeOfString:@"twitter"];
    if(domainRange.length > 0)
    {
        [storage deleteCookie:cookie];
    }
}
