Programmatically remove the header of UITableView and automatically resizes the content to fill in the removed area

Question

I have added a UIButton in the header section of the UITableView via the interface builder and would like to remove the access to the button in cer

Answer 1

Check if your tableView has a grouped style, in that case a white space appears at the top of the table. Change the style to plain and that blank space will be removed.

Answer 2

I created a boolean property called removeHeader and then when ever I want to remove my header I call:

func removeSectionHeader() {
        removeHeader = true
        self.tableView.reloadData()
    }

Then when my tableView reloads it will call this tableView delegate method:

func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
        if removeHeader {
            return 0.0
        } else {
            let height = self.tableView.sectionHeaderHeight
            return height
        }
    }

Answer 3

If you want to remove the table's header view, just set the myTable.tableHeaderView property to nil. If what you have is actually a section header, then you need to return nil from the viewForHeaderInSection method and call [myTableView reloadData]

Answer 4

You could also do:

- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section {
    return 0.0;
}

This seems to work for my (single) section header and avoids the need for reloadData.

Note that:

- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section

is still called, but its return value seems to be ignored.
