What's does "cardinality of an relationship" mean in Core Data?
- by dontWatchMyProfile
From the docs:
If all of a managed object's
relationship delete rules are Nullify,
then for that object at least there is
no additional work to do (you may have
to consider other objects that were at
the destination of the relationship—if
the inverse relationship was either
mandatory or had a lower limit on
cardinality, then the destination
object or objects might be in an
invalid state).
Does someone have an example of this cardinality thing? What's this good for and what's important to know about this? (sounds very important...)
