I am using Core Data in my app,
and maybe my users wants to delete all the NSManagedObjects that they once saved,
So is there a quick method of NSManagedObjectContext that can do this, I mean, clear the whole persistent store, or in another word,delete all objects of every entity, so there’s no actual objects (except entities) in core data?
Thanks a lot!
You can either delete everything entity-by-entity or clear the store file itself.
