Input gestures - Xamarin

With Xamarin, it is common to detect gestures using one of the recognizers defined in Xamarin Forms Gestures.

A gesture should not be the only way to trigger actions. Make sure to provide a second way, such as a button, to trigger the same action.

var pinchGesture = new PinchGestureRecognizer();
pinchGesture.PinchUpdated += (sender, event) => {
  // Provide alternative
};
view.GestureRecognizers.Add(pinchGesture);
