title: iphone - getting the button id in a segmented control
body: <p>I am trying to create something that uses the idea of the UIPopOverController, I mean, have that speech bubble anchor pointing to the button who triggered the method.</p>
  
  <p>The problem is that I am using a UISegmentedControl...</p>
  
  <p>How do I get the id of the button that was tapped on a UISegmentedControl, so I can determine its position and generate the anchor?</p>
  
  <p>thanks for any help.</p>
