MonoTouch.Dialog: Dismissing keyboard by touching anywhere in DialogViewController

I'm using DialogViewController from MonoTouch.Dialogs. I'd like to be able to dismiss the keyboard by clicking on the background of the dialog.

I usually employ the technique of filling the view with a large custom button and placing it behind all the other elements. However, I can't make this work in the DialogViewController. I did this in LoadView and it just froze all the other controls.

Is there a relatively straightforward way of achieving what I want?

In view controller:

public override void TouchesBegan (NSSet touches, UIEvent evt)
    {
        base.TouchesBegan (touches, evt);

        myField.ResignFirstResponder();
    }

Edit: From what I've read, you can use the TouchesBegan event for the cell subview instead of the table itself. I'm not positive that works. Good luck :)

His solution:

   var tap = new UITapGestureRecognizer ();
   tap.AddTarget (() =>{
       dvc.View.EndEditing (true);
   });
   dvc.View.AddGestureRecognizer (tap);
