Clear a whole Core Data using NSManagedObjectContext

Question

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!

Just delete the file and recreate your persistent store, then everything is nice and empty.

You can either delete everything entity-by-entity or clear the store file itself.
