title: Is there a way with Xamarin.Forms to detect the software keyboard in my iOS app?
body: <p>I have a Xamarin.Forms application with a login screen. I have added code to move the controls out of the way, when one of the Entry fields gets focus. I move the views back down in the Unfocus event handlers. In the simulator I can prevent the software keyboard from popping up. Unfortunately my event handlers still move the view up and down even without the keyboard. </p>
  
  <p>Is there a way to detect the keyboard's appearance in Xamarin.Forms, while in the event handlers on the ContentPage?</p>
