NSFetchedResultsController deallocated instance

Anyone ever encountered this ?

-[NSFetchedResultsController _restoreCachedSectionInfo]: message sent to deallocated instance

While performing fetch w开发者_JS百科ith performFetch: using NSFetchedResultsController instance.

I'm sure the NSFetchedResultsController is retained before performing the fetch.

That error is a hint that you are overreleasing something, probably the controller. Check your properties and count your retains and releases; there is any extra somewhere
