Implement the EKEventViewDelegate protocol then check for the delete event with...
-(void) eventViewController:(EKEventViewController *)controller didCompleteWithAction:(EKEventViewAction)action
{
if (action == EKEventViewActionDeleted) {
// Update unique event ID to core data & change text of button to new
_itemReminder = NULL;
_part.reminderID = NULL;
_savedEventFound = NO;
[_reminderButton setTitle: #"New" forState: UIControlStateNormal];
}
}
