How to dismiss keyboard when using DecimalPad

Question

I have a UITableView with a custom cell that has a TextField. I have the DecimalPad comes up, and as we all know, there is no done key. I previously had resolved this type of issue when I had a "Decimal only" textfield on a normal UIView by handling the TouchesEnded event and then checking to see if the TextField was the first responder and if so, it would then resign, but if that technique could work now then I'm not able to figure out who's TouchesEnded I should be using (The UIView that everything is presented on, the UITableView, the Cell, the CellControler, the TextField.. I think I've tried everything).

I'm hoping there's another, cleaner way of dealing with this.

Anyone?

I think David has the best idea - here is some Monotouch code to get you started. You will need to put this in the View Controller where the decimal pad is being shown:

UIView dismiss;

public override UIView InputAccessoryView 
{
    get 
    {
        if (dismiss == null)
        {
            dismiss = new UIView(new RectangleF(0,0,320,27));
            dismiss.BackgroundColor = UIColor.FromPatternImage(new UIImage("Images/accessoryBG.png"));          
            UIButton dismissBtn = new UIButton(new RectangleF(255, 2, 58, 23));
            dismissBtn.SetBackgroundImage(new UIImage("Images/dismissKeyboard.png"), UIControlState.Normal);        
            dismissBtn.TouchDown += delegate {
                 textField.ResignFirstResponder();
            };
            dismiss.AddSubview(dismissBtn);
        }
        return dismiss;
    }
}
