ios didReceiveAuthenticationChallenge状态

Question

我正在尝试通过网络服务器对用户进行身份验证，并在我的登录视图按钮触摸中调用以下方法来进行此操作。

- (void)connection:(NSURLConnection *)connection 
didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge
{
    NSLog(@"challenge failure %d", [challenge previousFailureCount]);

    // Access has failed two times...
    if ([challenge previousFailureCount] == 0)
    {
        //NSLog(@"desc %@",[connection description]);
        NSURLCredential *cred = [[[NSURLCredential alloc] initWithUser:userName.text password:passWord.text
                                                           persistence:NSURLCredentialPersistenceForSession] autorelease];
        [[challenge sender] useCredential:cred forAuthenticationChallenge:challenge];

        // need to call new view on correct authentication

            [connection release];

    }

    else {// Answer the challenge

            UIAlertView *alert = [[UIAlertView alloc]


                              initWithTitle:@"Authentication error" 
                              message:@"Invalid Credentials" delegate:self
                              cancelButtonTitle:@"Retry"
                              otherButtonTitles:nil];
        [alert show];
        [alert release];



    }

}

成功认证后是否返回任何状态，以便我可以使用该状态并传递到下一个视图，否则显示错误。

Answer 1

Jsut调用connectionDidFinishLoading：方法。

Answer 2

好的，正如我的评论中所述：

实际上，connectionDidFinishLoading：方法告诉您可以继续进行下一步。
