How to do this?

Answer 1

For hiding a section, even in the middle of the table view you would need all of the following

#define DEBUG_SECTION 1

#if ! DEBUG_BUILD
- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section
{
    if (section == DEBUG_SECTION)
        return CGFLOAT_MIN;
    return [super tableView:tableView heightForHeaderInSection:section];
}
//------------------------------------------------------------------------------

- (CGFloat)tableView:(UITableView *)tableView heightForFooterInSection:(NSInteger)section
{
    if (section == DEBUG_SECTION)
        return CGFLOAT_MIN;
    return [super tableView:tableView heightForFooterInSection:section];
}
//------------------------------------------------------------------------------

- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section
{
    if (section == DEBUG_SECTION)
        return nil;
    return [super tableView:tableView titleForHeaderInSection:section];
}
//------------------------------------------------------------------------------

- (NSString *)tableView:(UITableView *)tableView titleForFooterInSection:(NSInteger)section
{
    if (section == DEBUG_SECTION)
        return nil;
    return [super tableView:tableView titleForFooterInSection:section];
}
//------------------------------------------------------------------------------

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    if (section == DEBUG_SECTION)
        return 0;
    return [super tableView:tableView numberOfRowsInSection:section];
}
//------------------------------------------------------------------------------
#endif // #if ! DEBUG_BUILD

if you left out titleFor/headerFor... you will get some empty rows
if you left out heightFor... the title/footer header text will still appear
