Answer 1

1) If you want fire notifications every month, even if user didn't open an app more then month, you should set several notifications (up to 60). For example, set notifications for next 12 month.
2) You should set notifications by this code (on loop, 12 times):
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
3) Before you set new notifications, remove old with this code:
[[UIApplication sharedApplication] cancelAllLocalNotifications];
