title: How can I enable multiple segments of a UISegmentedControl to be selected?
body: <p>Lets say my UISegmentedControl has 8 numbered segments. I would like for the user to be able to turn on 2, 3, or more of them at once. Toggling them. Essentially like a bits in a byte. Is this possible? I believe it is on regular Mac OS X but I can't seem to find a way to do it in the iPhone SDK.</p>
  
  <p>If I have to simulate this by putting buttons into a view, is there any way to do the following:</p>
  
  <ol>
  <li>Round the corners of the view so that it looks like the "bar" style UISegmentedControl?</li>
  <li>Use the built-in backgrounds the "bar" style has on the buttons?</li>
  <li>Give the buttons a shadow like the whole "bar" style has? (not the text)</li>
  </ol>
