EKEventstore和唯一的日历标识符

Question

I have a question about EKCalendar's calendarIdentifier property. Is this ID unique on a global level, or on a per-source level? Eg can I safely store the calendarIdentifier in my app to smoothly identify a calendar across all calendars in the event store (no matter what EKSource they're in) or do I also need to save the EKSource's identifier associated with the calendar?

I have a calendar selection feature in my app, and I want to safely store and load the correct calendar (within the correct account) upon app restart.

Thanks in advance.

From my personal experience and from the description of the property in EKCalendar's class reference it is local to the EKEventStore . An EKCalendar has an EKSource as it's property at the same level as the calendarIdentifier string.
