Core Data on iOS -- get specific changes done to object

Is it possible to get the specific changes done to an object in NSFetchedResultsControllerDelegate's controller:didChangeObject:atIndexPath:forChangeType:newIndexPath: method?

While I'm looking for a pretty solution, I guess a hack would be fine too...

Thanks, A. Dvorak


You get the change type, that tells you broadly what happened and covers the insert / delete / move. The only case where you need more details is on an update type. In this case, you have the object so you can call changedValues or changedValuesForCurrentEvent on it to get the required details.
