title: Test if app did become active from a UILocalNotification
body: <p>Is there a way to know if the application did become active from a local notification? </p>
  
  <p>I know there is a way to test if the application was <strong>launched</strong> from a local notification alert; but if it just was sitting out there the background, and received a notification?</p>
  
  <p>I need to run different code, when the app has become active:</p>
  
  <ol>
  <li>From a local notification. </li>
  <li>Just has become active :)</li>
  </ol>
  
  <p>Is there a way to do it?</p>
