I am guessing you are using a NSFetchedResultsController? If you are not then you need to be with a UITableView. Once you do, make sure you have your UITableViewDatasource configured as the delegate to the NSFetchedResultsController. Once you do that, you will not need to call -reloadData at all because the NSFetchedResultsController will monitor changes in the NSManagedObjectContext and update the UITableViewDatasource as needed via the delegate methods.
