title: How to clear the remote notification in your app?
body: <p>Is there a way to clear the remote notification from the notification banner when swiping down from the top of the iPhone screen. I tried setting the badge number to zero:</p>
  
  <pre><code>application.applicationIconBadgeNumber = 0 
  </code></pre>
  
  <p>in delegate <code>didFinishLaunchingWithOptions</code>, and <code>didReceiveRemoteNotification</code>, but it did not clear the notifications. Thanks.</p>
