title: Are there examples of how to use UIPopoverController on iOS?
body: <p>I've seen some demos where UIPopoverController is used and would like to use it in my apps.</p>
  
  <p>So does anyone have any good tutorials that you could link me?</p>
  
  <p>Is it possible to use it in relation to UISegmentedControl where different popover windows are summoned when different segments are selected as a type of a switch view function?</p>
