title: Reset push notification settings for app
body: <p>I am developing an app with push notifications. To check all possible ways of user interaction, I'd like to test my app when a user declines to have push notifications enabled for my app during the first start. </p>
  
  <p>The dialog (initiated by <code>registerForRemoteNotificationTypes</code>), however, appears only once per app. How do I reset the iPhone OS's memory of my app. Deleting the app and reinstalling doesn't help. </p>
