Objective C:Object Deallocated while key value observers were still registered with it

Question

I am hitting the below error after I added 2 additional fields to my core data model.

CarPark_CarPark_ was deallocated while key value observers were still r         


        

Answer 1

It's probably due to the observer being deallocated before the objects being observed. You would need to implement the -(void) dealloc method to remove all observed objects in the observer.
