Title
Body
I have an app that is using UIKit state preservation in iOS 6. I am able to save/restore the state of the view controllers, ie which tab is selected and navigation controller hierarchy, however I cannot get my table view to restore it's offset. I have a restoration identifier in my storyboard for the view as well as the view controller and the view controller (the table's data source) implements UIDataSourceModelAssociation as follows: - (NSString *)modelIdentifierForElementAtIndexPath:(NSIndexPath *)indexPath inView:(UIView *)view { TSStatus *status = [self._fetchedResultsController objectAtIndexPath:indexPath]; return status.objectID.URIRepresentation.absoluteString; } - (NSIndexPath *)indexPathForElementWithModelIdentifier:(NSString *)identifier inView:(UIView *)view { NSURL *statusURL = [NSURL URLWithString:identifier]; NSManagedObjectID *statusID = [[TSDataController sharedController].persistentStoreCoordinator managedObjectIDForURIRepresentation:statusURL]; TSStatus *status = (TSStatus *)[[TSDataController sharedController].mainContext objectWithID:statusID]; return [__fetchedResultsController indexPathForObject:status]; } modelIdentifierForElementAtIndexPath:inView: is getting called when the app goes into the background, however modelIdentifierForElementAtIndexPath:inView: never gets called.
