Answer 1

Just return 0 in heightForHeaderInSection tableview delegate method...
- (CGFloat) tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section {
// Specific section
if (section == 0)
return 0.0f;
// all sections
return 0;
}

Answer 2

I think you need change in bellow method
-(CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section
{
return CGFLOAT_MIN;
}
And Remove this method
- (NSString *)tableView:(UITableView *)tableViewtitleForHeaderInSection:(NSInteger)section
{
if (section == 0)
{
return nil;
}
else
{
return [storename2 objectAtIndex:section];
}
}
This will hide all the section header in your tableview.

Also don't forget to set UITableview Delegate & datasource.
- (void) viewDidLoad {
[super viewDidLoad];
self.tableView.contentInset = UIEdgeInsetsMake(-1.0f, 0.0f, 0.0f, 0.0);
}
- (CGFloat) tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section {
// Specific section
if (section == 0)
return 0.0f;
// all sections
return 0;
}
- (NSString*) tableView:(UITableView *) tableView titleForHeaderInSection:(NSInteger)section
{ // Specific section
if (section == 0) {
return nil;
} else {
// all sections
// return some string here ...
return nil;
}
}

Use switch-case to handle multiple section height.
func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
let headerHeight: CGFloat
switch section {
case 0:
// first section for test - set value for height
headerHeight = 0
default:
// other Sections - set value for height
headerHeight = 0
}
return headerHeight
}
