title: iPhone SDK: How do I create an overlay drop-down menu?
body: <p>I have a UIViewController containing its UIView which occupies the available screen (inbetween the tabbar and nav bar).</p>
  
  <p>I'd now like to add a simple toolbar which is situated at the top of the UIView which will contain some buttons. One of the buttons should display a drop down menu which is displayed as an overlay over the UIView. I'd quite like this menu to be a UITable as it could contain many items.</p>
  
  <p>The problem I'm having is I can't see the best way to go about this. I'm wondering whether there's a simple strategy.</p>
  
  <p>Here's an example of the type of feature I'm looking for...</p>

  <p>I expect the above example is emulated in UIWebView using HTML/CSS. Is there a "proper" way?</p>
  
  <p>TIA</p>
