title: Run action if a existing screen interaction passes over and stops on a UIView
body: <p>How do I add an action to a uiview that will run if a screen interaction (long press) moves to a uiview and then stays there for a select period of time.</p>
  
  <p>EDIT: I have a drop down menu sort of system and a long press on the button reveals the menu. Then a user would slide down onto an option and then release the tap. I want to tell which menu item that happened on and act accordingly.</p>
