Ios 将行数放入节标题中

我需要在小节标题中包括行数，比如今天（6），这意味着在今天标题的小节中有6行（在我的例子中是核心数据对象）。我知道在这里可以找到：

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
    {
        id<NSFetchedResultsSectionInfo> sectionInfo = [[self.fetchedResultsController sections]objectAtIndex:section];
        return [sectionInfo numberOfObjects];
    }

-（NSInteger）表视图：（UITableView*）表视图行数节：（NSInteger）节
{
id sectionInfo=[[self.fetchedResultsController节]objectAtIndex:section]；
返回[sectionInfo numberOfObjects]；
}

但是我不知道如何在每一个部分中都包含这个标签文本。 欢迎任何建议
