Coredata - “NSObjectInaccessibleException - CoreData could not fulfill a fault”

Question

I am new to Core data and still figuring out the nuts and bolts and this error has been bugging me for hours and I cant seem to find a solution. Any help is greatly appreciated.

Answer 1

Your over releasing fetchedObjects in your readFromCoreData method. executeFetchRequest will return to you autoreleased objects anyway. When the current run loop finished executing (when you're jumping from views) then it attempt to release the objects twice (assuming you haven't used your own autorelease pools).

I'd change

return [fetchedObjects autorelease]; 

to

return fetchedObjects;
