title: iOS clear push notifications
body: <p>I notice that for apps like Google Hangout, Facebook etc. when I get a push notification for any event (people writing on my wall, etc.), if I view the event on my desktop, it will clear the push notification (which I have not cleared myself or opened the app for) on my iPhone.</p>
  
  <p>How can I implement the same?</p>
  
  <p>Right now i'm using <a href="https://github.com/stephenmuss/django-ios-notifications" rel="nofollow">this</a> app for implementing my push's.</p>
  
  <p>I customized the above, but the implementation is similar. Do I need to send any special data to the phone to clear all notifications from my app?</p>
