ios - UIWebView 身份验证在 iOS 7.1 中不再有效

Question

自升级到 iOS 7.1 后，我的应用程序出现了一些严重问题。 WebView 和身份验证质询工作正常。由于我已升级，webview 不再显示内容。身份验证似乎工作正常，因为我通过调试 + NSLog 获得了正确的值，因此无效的凭据不是问题(检查了大约 10 次)。在 webview 使用有效凭据重新加载页面后，仍然没有显示任何内容。这是我的代码:

- (void)viewDidLoad
{
    _authed = NO;
    [self.webView loadRequest:[NSURLRequest requestWithURL: [NSURL URLWithString:@"xxx"]]];
}

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType;
{
    NSLog(@"Did start loading: %@ auth:%d", [[request URL] absoluteString], _authed);

    if (!_authed) {
        _authed = NO;
        [[NSURLConnection alloc] initWithRequest:request delegate:self];
        return NO;
    }
    return YES;
}

- (void)connection:(NSURLConnection *)connection willSendRequestForAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge
{

    if ([challenge previousFailureCount] > 0) {

    }
    else
    {

        NSURLCredential *credential = [NSURLCredential credentialWithUser:@"xxx"
                                                                 password:@"xxx"
                                                              persistence:NSURLCredentialPersistencePermanent];
        [[challenge sender] useCredential:credential forAuthenticationChallenge:challenge];
    }

}

- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge;
{
    NSLog(@"got auth challange");

    if ([challenge previousFailureCount] == 0) {
        _authed = YES;
        [[challenge sender] useCredential:[NSURLCredential credentialWithUser:@"xxx" password:@"xxx"  persistence:NSURLCredentialPersistencePermanent] forAuthenticationChallenge:challenge];
    }
    else
        [[challenge sender] cancelAuthenticationChallenge:challenge];
}

- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response;
{
    NSLog(@"received response via nsurlconnection");

    NSURLRequest *urlRequest = [NSURLRequest requestWithURL:[NSURL URLWithString: @"xxx"]];

    [self.webView loadRequest:urlRequest];
    _authed = YES;
}


- (BOOL)connectionShouldUseCredentialStorage:(NSURLConnection *)connection;
{
    return NO;
}

NSLog输出:

2014-04-17 12:23:20.418 Test[510:60b] Did start loading: xxx auth:0

2014-04-17 12:23:20.704 Test[510:60b] received response via nsurlconnection

2014-04-17 12:23:20.710 Test[510:60b] Did start loading: xxx auth:1

提前致谢。

您可以在 url 中而不是请求 header 中传递身份验证请尝试代替 BASE_URL: NSString* urlString = [NSString stringWithFormat:@"%@//%@:%@@%@",@"http:",userName,password,myUrl]
