Xamarin iOS：通过http传递凭证

Question

我想通过我的xamarin iOS项目上的http传递凭据，但它不工作。

public partial class WebView : UIViewController 
{ 

     protected override void ViewDidLoad() 
     { 
     webView.LoadRequest(new NSUrlRequest(new NSUrl("https:example.com"))); 
     webView.AllowsBackForwardNavigationGestures = true; 
     webView.NavigationDelegate = new WebViewDelegate(this); 
     } 
} 

public class WebViewDelegate : WKNavigationDelegate, INSUrlConnectionDataDelegate 
    { 

     public override void DidReceiveAuthenticationChallenge(WKWebView webView, NSUrlAuthenticationChallenge challenge, Action<NSUrlSessionAuthChallengeDisposition, NSUrlCredential> completionHandler) 
     { 
      //base.DidReceiveAuthenticationChallenge(webView, challenge, completionHandler); 
      completionHandler(NSUrlSessionAuthChallengeDisposition.PerformDefaultHandling, new NSUrlCredential("username", "password", NSUrlCredentialPersistence.ForSession)); 
      Console.WriteLine("We are authenticated"); 
      return; 
     } 
} 

任何人都可以建议如何解决这个问题？

更新：

DidReceiveAuthenticationChallenge被调用，并正在以不断循环调用。不但得不到预期的页面，我得到一个空白页面，它只是说，“验证”

从苹果的doc上PerformDefaultHandling：

使用默认处理的挑战，因为虽然此委托方法不实现。提供的凭证参数被忽略。

尝试UseCredential代替：

var crendential = new NSUrlCredential("user", "pass", NSUrlCredentialPersistence.ForSession); 

completionHandler(NSUrlSessionAuthChallengeDisposition.UseCredential, crendential);
