How to hide first section header in UITableView (grouped style)

Question

As the design of table views using the grouped style changed considerably with iOS 7, I would like to hide (or remove) the first section header. So far I haven\'t managed to

Answer 1

this way is OK.

override func tableView(tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
    if section == 0 {
        return CGFloat.min
    }
    return 25
}

override func tableView(tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
    if section == 0 {
        return nil
    }else {
        ...
    }
}

Answer 2

Update[9/19/17]: Old answer doesn't work for me anymore in iOS 11. Thanks Apple. The following did:

self.tableView.sectionHeaderHeight = UITableViewAutomaticDimension;
self.tableView.estimatedSectionHeaderHeight = 20.0f;
self.tableView.contentInset = UIEdgeInsetsMake(-18.0, 0.0f, 0.0f, 0.0);

Previous Answer:

As posted in the comments by Chris Ostomo the following worked for me:

- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section
{
    return CGFLOAT_MIN; // to get rid of empty section header
}

Answer 3

I just copied your code and tried. It runs normally (tried in simulator). I attached result view. You want such view, right? Or I misunderstood your problem?

Answer 4

In Swift 4.2 and many earlier versions, instead of setting the first header's height to 0 like in the other answers, you can just set the other headers to nil. Say you have two sections and only want the second one (i.e., 1) to have a header. That header will have the text Foobar:

override func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
    return section == 1 ? "Foobar" : nil
}

Answer 5

Swift3 : heightForHeaderInSection works with 0, you just have to make sure header is set to clipsToBounds.

func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
       return 0
}

if you don't set clipsToBounds hidden header will be visible when scrolling.

func tableView(_ tableView: UITableView, willDisplayHeaderView view: UIView, forSection section: Int) {
    guard let header = view as? UITableViewHeaderFooterView else { return }

    header.clipsToBounds = true
}

Answer 6

This is how to hide the first section header in UITableView (grouped style).

Swift 3.0 & Xcode 8.0 Solution

1. The TableView's delegate should implement the heightForHeaderInSection method

2. Within the heightForHeaderInSection method, return the least positive number. (not zero!)

   func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
   
       let headerHeight: CGFloat
   
       switch section {
       case 0:
           // hide the header
           headerHeight = CGFloat.leastNonzeroMagnitude
       default:
           headerHeight = 21
       }
   
       return headerHeight
   }
