title: iOS Urban Airship de-register notifications
body: <p>Good Day,</p>
  
  <p>The API on iOS for Urban Airship for registration is available. Basically it is just </p>
  
  <pre><code>[[UAPush shared] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeBadge |
                                                       UIRemoteNotificationTypeSound |
                                                       UIRemoteNotificationTypeAlert)];
  </code></pre>
  
  <p>However, there doesnt seem to be any API to de-register the device from receiving notifications at all. What can I do? I mean I could "register" it to a "inactive" alias account but this doesnt seem very good.</p>
