Changing UITableView's section header/footer title without reloading the whole table view
If you just have a basic text header or footer, you can access them directly:
[tableView footerViewForSection:indexPath.section].textLabel.text = [self tableView:tableView titleForFooterInSection:indexPath.section];
similarly for the header:
[tableView headerViewForSection:indexPath.section].textLabel.text = [self tableView:tableView titleForHeaderInSection:indexPath.section];
This should work:
UIView.setAnimationsEnabled(false)
tableView.beginUpdates()
if let containerView = tableView.footerViewForSection(0) {
containerView.textLabel!.text = "New footer text!"
containerView.sizeToFit()
}
tableView.endUpdates()
UIView.setAnimationsEnabled(true)
I managed to do it in an indirect way: I created a UILabel and set it as section header/footer.
- (UIView *)tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section {
// update sectionFooterView.text
return sectionFooterView;
}
- (void)viewDidLoad {
// create sectionFooterView in Interface Builder, change the frame here
// use Font-size:15 , BG-Color: clearColor , text-Color: RGB=(97,105,118)
// and Text-alignment:Center to look like table view's original footer
sectionFooterView.frame = CGRectMake(0, 10, 320, 12);
}
Does anyone know a way to do this without setting a custom footer view?
