ios - NSFetchedResultsController - track changes only to a subset of the properties -


the nsfetchedresultscontroller monitors changes whole managed object that's keeping track of. whenever property modified in current context, instance

– controller:didchangeobject:atindexpath:forchangetype:newindexpath:

gets called. of course affect performance of uitableview hooked frc, if changes happen frequently.

no can't.
if need finer grain observation, separate properties different entity.
