How to retrieve events that has been changed in EKEventStoreChanged notification

Question

I have listened for the notification and whenever there is a modification or change, I am synchronising all the events to the local db. But the problem I have is to know whether I can retrieve only the modified events. This is the EKStoreChanged notification's Userinfo,

     "x-apple-eventkit:///Event/p1003",
     "x-apple-eventkit:///Location/p60",
     "x-apple-eventkit:///Location/p61",
     "x-apple-eventkit:///Location/p59",
     "x-apple-eventkit:///Event/p1004",
     "x-apple-eventkit:///Event/p1005"

Is it possible to know which event has been changed, or whether it has been deleted?

From apple's documentation:

Posted whenever changes are made to the Calendar database, including adding, removing, and changing events or reminders. Individual changes are not described.

So, you need to fetch each entry to known wether it has changed or not.
