How can I do some custom stuff before my NSManagedObjectContext

override my NSManagedObject didTurnIntoFault.
So, to do this, is it safe for me to subclass NSManagedObjectContext
and override save:? Or is this one of those methods I should not
override? Any better ways?
As you long as you call super's implementation (obviously!), then yes
it's safe. But watch out for the fact that during a store migration,
Core Data may well internally use a different MOC and save it,
ignoring your subclass.
