title: Getting top UIWIndow/UIView on device using public/non-public/private API
body: <p>I'm trying to find out how to find the top most view using non-public/private api, is there any way doing it (iOS 7.1.2)?</p>
  
  <p><strong>Edit:</strong></p>
  
  <p>Maybe I wasn't clear,
  I want to get the top most view no matter what app is active now (facebook, whatsapp, games, lockscreen, calendar, etc.).</p>
