This may actually be a bug in the Calendar Store documentation. I 
believe you only need to register for notifications with 
NSNotificationCenter.

Calendar Store uses distributed notifications behind the scenes to 
make this possible. You should only need to register for notifications 
with the local notification center, and Calendar Store will take care 
of the rest.
