Putting number of rows in section title - ios

Question

I would need to include the number of rows in the section title, like TODAY (6), that means that on section titled TODAY there are 6 rows (core data objects in my case). I know that it is to find here:
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
id<NSFetchedResultsSectionInfo> sectionInfo = [[self.fetchedResultsController sections]objectAtIndex:section];
return [sectionInfo numberOfObjects];
}
But I don't know how to include this on each section to be shown as a label text.
Any advice is welcome....
