从NSFetchedResultsController中删除部分时更新UITableView

Question

UITableView question :

I use Core Data and this delegate method to update my table view (of course with couple willChange and didChange)

- (void)controller:(NSFetchedResultsController *)controller didChangeSection:(id <NSFetchedResultsSectionInfo>)sectionInfo
       atIndex:(NSUInteger)sectionIndex
 forChangeType:(NSFetchedResultsChangeType)type {

Why the sections under my table view are not updated if I don't ask reloadData in the end of this delegate method ?!

It's difficult to tell without seeing your code.However, silly as it seems, you may have forgotten to set the NSFetchedResultsController's delegate. Check this in your code.
