title: Clear notifications badge without removing notifications
body: <p>In my app, I'm receiving push notifications with badge number set to one. 
  When app will start, it should set badges count to 0, so I'm using:</p>
  
  <pre><code>[[UIApplication sharedApplication] setApplicationIconBadgeNumber:0];
  </code></pre>
  
  <p>And it works, but also it removes all notifications from notifications center.<br/>
  Is there a way to clear badges without removing notifications?</p>
