title: UILocalNotifcation - Respond to notification even if app launched via home screen
body: <p>I am sending out local notifications within my app; if the user responds to the notification the app calls the delegate method below and I can handle it:</p>
  
  <pre><code>  - (void)application:(UIApplication *)app didReceiveLocalNotification:(UILocalNotification *)notif 
  </code></pre>
  
  <p>If the user doesn't respond to the notification but opens the app after, I would like to handle it the same way I would if they responded to the notification.</p>
  
  <p>I also checked if the app is launching with launch options but this only seems to be called if they respond directly to the notification.</p>
  
  <p>What is the best way to check that a notification has been fired but the user has responded of their own accord?</p>
