18. unregisterForRemoteNotifications()
    Unregister for all remote notifications received via
    Apple Push Notification service.
    You should call this method in rare circumstances only,
    such as when a new version of the app removes support
    for all types of remote notifications. Users can
    temporarily prevent apps from receiving remote
    notifications through the Notifications section of the
    Settings app. Apps unregistered through this method can
    always re-register.
