title: How do I know if a user has already accepted/refused ios notifications with React-Native?
body: <p>I would like to display a custom screen asking the user to accept or refuse notifications on their iOS device. This screen should only be displayed if the user never registered or never accepted/refused notifications for the app. </p>
  
  <p>Though, I don't seem to find a way to know if the user already registered or not. And I don't want to use any kind of async storage as this could be cleaned up by the user.</p>
  
  <p>I found the method <code>PushNotificationIOS.checkPermissions</code> but this doesn't tell me if the user has registered yet. </p>
  
  <p>I need a way to know if the user has "not yet registered", "accepted" or "declined".   </p>
  
  <p>If the user has not yet registered, I display the screen. If the user has accepted or declined the notifications, I don't display the screen. </p>
  
  <p>Is there a way with React-Native to know this?</p>
  
  <p>Thanks</p>
