- iOS 10.0+
- tvOS 10.0+

When this property is
false, the notification is delivered only once. When this property is
true, the notification request is rescheduled automatically, resulting in the notification being delivered each time the trigger condition is met. To unschedule the notification request, use the methods of the
UNUser to remove the notification request.
