nsurlconnection中调用的身份验证挑战

Question

我正在用链接创建nsurlconnection https://www.wella.com，最终传递给 UIWebView

NSURL *url = [NSURL URLWithString:[[u stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
self.authRequest = [NSURLRequest requestWithURL:url cachePolicy:NSURLRequestReloadIgnoringLocalAndRemoteCacheData timeoutInterval:30];
self.authConnection = [NSURLConnection connectionWithRequest:authRequest delegate:self];

我意外地接受了身份验证挑战，当然我目前没有处理哪些。我注意到，当使用桌面浏览器时，当我粘贴上面的链接时，它的地址会自动更改为https://www.wella.com/professional/countryselector

粘贴扩展链接时， NSURLConnection毫无问题地工作。我该如何摆脱这一挑战，并能以某种方式与该链接自动更改联系在一起？

编辑：我已经解决了它。但是，问题仍然存在：为什么自动链接更改会导致调用身份验证挑战？

谢谢：muralikrishna的答案我通过实现NSURLConnectionDelegate方法并设置信任凭据：

来管理它：

- (void)connection:(NSURLConnection *)connection willSendRequestForAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge {
    SecTrustRef trust = challenge.protectionSpace.serverTrust;
    NSURLCredential *cred;
    cred = [NSURLCredential credentialForTrust:trust];
    [challenge.sender useCredential:cred forAuthenticationChallenge:challenge];
}
