title: How to change the color of UISegmentedControl? My tint doesn't display
body: <p>I am trying to have a simple <code>UISegmentedControl</code> with a <code>tint</code>. In the <code>xcode interface</code>, I chose the following parameters:</p>
  
  <pre><code>- Style = bar
   - Tint = red
   - Image = blank
  </code></pre>
  
  <p>When viewed on <code>storyboard</code>, I see a nice segmented control with a dark red drop shadow, but on my phone I just see a nearly white control bar when I don't have any <code>UIImage</code> arranged behind the segmented control. If I place a blank <code>UIImage</code> with a black background behind the segmented control, the segmented control appears a nice dark grey with a black drop shadow and white letters, but no red is seen.</p>
  
  <p>Does anyone know how to see the red tint that is present in <code>storyboard</code> on my actual phone?</p>
