C# UIWebView中的Windows身份验证url无响应、无错误、请求-Xamarin.iOS

我正在尝试在UIWebView中加载windows身份验证url。下面是我的代码

public override void WillSendRequestForAuthenticationChallenge(NSUrlConnection connection, NSUrlAuthenticationChallenge challenge)
        {
            if (challenge.ProtectionSpace.AuthenticationMethod == NSUrlProtectionSpace.AuthenticationMethodNTLM)
            {
                if (challenge.PreviousFailureCount > 0)
                {
                    challenge.Sender.CancelAuthenticationChallenge(challenge);
                }
                else
                {
                    var credentialSpace = new NSUrlProtectionSpace("http://authenticatedurl.com", 80, "http", "http://authenticatedurl.com", "NTLM");
                    NSUrlCredentialStorage credentialStorage = NSUrlCredentialStorage.SharedCredentialStorage;
                    var credential = new NSUrlCredential ("username", "password", NSUrlCredentialPersistence.ForSession);
                    credentialStorage.SetDefaultCredential (credential, credentialSpace);
                    connection.UseCredential (credential, challenge);
                    connection.PerformDefaultHandling (challenge);
                    isAuthenticated = true;
                }
            }
        }

调用上述委托并成功执行UserCredential，但未加载网站。它持续旋转了几个小时。我做错了什么

var credentialSpace=新 NSUrlProtectionSpace（“”，80，“http”， “NTLM”）

试试这个

var credentialSpace=新 NSUrlProtectionSpace（“authenticatedurl.com”，80，“http”， “authenticatedurl.com”、“NTLM”）

它应该有用
