Default height for section header in UITableView

Question

I want to set the height of the first header in my UITableView. For the other headers I want them to remain the default height. What value/constant can I put in place of \"s

Answer 1

For swift 4.2 you should return UITableView.automaticDimension

Answer 2

To get the default height, just let super handle it:

- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section
{
    if (section == 0)
        return kFirstHeaderHeight;

    return [super tableView:tableView heightForHeaderInSection:section];
}

Answer 3

From checking the defaults in my app it looks like for a grouped table the default is a height of 22 and for a non-grouped table the default is a height of 10.

If you check the value of the property sectionHeaderHeight on your tableview that should tell you.

Answer 4

This should do the trick

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
    if(indexPath.section == CUSTOM_SECTION)
    {
        return CUSTOM_VALUE;
    }
    return [tableView rowHeight];
}

Answer 5

In IOS 5.0 onwards you can return UITableViewAutomaticDimension in most of the delegate methods. Its at the bottom of the documentation page

- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section
{
    if(section == CUSTOM_SECTION)
    {
        return CUSTOM_VALUE;
    }
    return UITableViewAutomaticDimension;
}

Answer 6

Actually do the trick :)

- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section
{
    if(section == 0)
        return kFirstSectionHeaderHeight;
    return [self sectionHeaderHeight];
}
