title: How to inform Passbook to remove pass from server?
body: <p>Now I can update passes in Passbook with Push Notification, but when passes ared used on server, I want to inform Passbook to remove these passes, I can't find any solutions in the Documents.</p>
  
  <p>I just know I can revoke removePass interface of PassKit in my App, the problem is the passes are not used through my App, but my another client App, so this method is not ok for me.</p>
  
  <p>Anyone know is there any other solutions to fix this problem?</p>
