objective c - For custom cell in viewForHeaderInSection reload particular viewForHeaderInSection IOS

I want to reload viewForHeaderInSection in case of custom cell in viewForHeaderInSection to reload particular viewForHeaderInSection IOS.

I have used following code

[self.tableView reloadSections:[NSIndexSet indexSetWithIndex:section] withRowAnimation: UITableViewRowAnimationAutomatic];

But whole section will reload

I have try the following too By creating custom view

SearchHeaderView is custom view

  - (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section{

            lblPrice_Header.text = [NSString stringWithFormat:@"%d",cartSum] ;
            return SearchHeaderView;

        }

 -(void)cartSum :(id)sender{
   .....
   .......
    =======================================
     cartSum =cartSum+[[subArray objectAtIndex:j]  intValue]*price;

        UIView *headerVw = [self.tableView headerViewForSection:section];
        [headerVw setNeedsDisplay];
        [headerVw setNeedsLayout];

    }

But It wont reload the section.

I have got my section header as below

You can try something like this:

UIView *headerVw = [YOURTABLEVIEW headerViewForSection:section];
[headerVw setNeedsDisplay];
[headerVw setNeedsLayout];

Note:

  • To deal with specific view you can define tags As well

Hope it will work for you.
