title: UISegmentedControl selected segment color
body: <p>Is there any way to customize color of selected segment in <code>UISegmentedControl</code>?</p>
  
  <p>I've found <code>segmentedController.tintColor</code> property, which lets me customize color of the whole segmented control. 
  The problem is, when I select bright color for <code>tintColor</code> property, selected segment becomes almost unrecognizable (its color is almost the same as the rest of segmented control, so its hard to distinguish selected and unselected segments). So I cannot use any good bright colors for segmented control. 
  The solution would be some separate property for selected segment color but I cannot find it. Did anyone solve this?</p>
