How can I determine when a user has ever seen a dialog asking for permission to push notifications (ios)

I am aware of enabledremotenotificationtypes, but that does not help me, because if I get enabledremotenotificationtypes == UIRemoteNotificationTypeNone, I will not be able to tell if user 1. received push notifications once, and then disabled it through installation later OR 2. rejected Push notifications OR 3. Never seen a blue dialog asking for permission. I need a way to differentiate these three cases.

Any help would be really appreciated.
