title: How we can authenticate webview with username and password in xamarin.forms for iOS?
body: <p>I recently started development using Xamarin. Forms and I am new to C#. I have a URL which I am using for resetting password, this URL is an HTML page and I am loading it in a Webview. If we open this URL in a browser it will ask for authentication i.e Username and Password, but I am not able to open this on iOS.
  I have created custom class for Webview in Android and iOS. For Android it's working fine but in iOS it's not.</p>
  
  <p>Code:</p>
  
  <pre><code>private void WillSendRequestForAuthenticationChallenge
  (NSUrlConnection connection, NSUrlAuthenticationChallenge challenge)
  </code></pre>
  
  <p>But I am not sure how to use this. Thanks in advance.</p>
