Remove Local Notification created from previous app version

Question

I need to create a new version of my app, but removing a section where user had the ability to create Local Notification. UILocalNotification

My doubt is that if a user has created an event with repetition, the notification center still launchs alerts.

Could i call cancelAllLocalNotifications to be sure that every notifications previously created would be removed ? Is there a better way to obtain that ?

Answer 1

Yes, you can call cancelAllLocalNotifications to cancel all scheduled notification when you app first launched. Of course you have to determine if your app is first launched.
