title: iPhone tableview drop-down menu
body: <p>I have a view controller with a table view in it and several buttons.  I would like to add an additional tableview on top of the view like this (or at least what it would look like if anybody wanted to be my friend :-)):</p>
  
  <p><img src="https://i.stack.imgur.com/SneWv.png" alt="TableViewPopdown"></p>
  
  <p>I don't want to just add this as a subview (like <a href="https://stackoverflow.com/questions/8060681/uitextfield-with-a-dropdown-menu-for-iphone">here</a> or <a href="https://stackoverflow.com/questions/4714138/how-to-create-iphone-toolbar-dropdown-expanded-menu">here</a>)enter link description here since I don't want to check which table view is being used in my tableview delegate and datasource methods.  I would rather use a separate view controller.  </p>
  
  <p>I don't want to use a picker because I need to display a bit of info with the items in the list.</p>
  
  <p>I have no problem creating the view with the corresponding controller, but how do I add it on top of the current view, just hiding portions of it?</p>
  
  <p>Thanks!</p>
