How to get local calendar update callback

Question

Is there any way to receive a callback from EKEventStore or from EKCalendar if an event is added to it from external sources (other device, google) ?

Answer 1

So i have there is an listener to the EKEventStore

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(receiveEventStoreChangedNotification:) name:EKEventStoreChangedNotification object:nil];

and it get called every time when EventStore data is changed.
