Given an NSManagedObject with optional to-one relationships, how do I check if they are empty or not?
This is a purely theoretical 'what if' question, so no pressure to rush to an answer. I'd prefer an answer that works in the context of a subclassed NSManagedObject, but I'll accept one that's based on the parent.
I know that if the relationship is to-many, I simply check and see the count of the NS(Ordered)Set, but when you have a to-one relationship, I'm not sure what I'd do.
