You can use Gestures.
label.AddGestureRecognizer(new UILongPressGestureRecognizer(this, new
Selector("longTap:")));
label.AddGestureRecognizer(new UISwipeGestureRecognizer(this, new
Selector("labelSwipe")) {
Direction = UISwipeGestureRecognizerDirection.Right,
NumberOfTouchesRequired = 1
});
//this one is needed or nothing happens
label.UserInteractionEnabled = true;
[Export("labelSwipe")]
public void SwipeOnLabel(UISwipeGestureRecognizer sender)
{
if (sender.State == UIGestureRecognizerState.Ended)
{
....
[Export("longTap:"), Preserve]
public void LongTap(UILongPressGestureRecognizer sender)
{
