How to hide a section in UITableView?

Question

There are some section in the table that does not contain any data and would like to hide that section.

How to do this?

Answer 1

If you return 0 for the height of the section, Apple API will ignore it. So just return a small value greater than 0.

- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section {
  if (section == 0) {
    return 1;
  }

  return 44;
}

Also implement view for header and return nil for the section you don't want to show.

- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section {
  if (section == 0 && !self.personaCells.count) {
    return nil;
  }

  UIView *headerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, tableView.frame.size.width, 44)];
  UILabel *headerLabel = [[UILabel alloc] initWithFrame:CGRectMake(15, 20, headerView.frame.size.width, 20)];
  NSString *headerTitle = @"SAMPLE TITLE";
  headerLabel.text = headerTitle;    
  [headerView addSubview:headerLabel];
  return headerView;
}
