How to find TableView section header Index Path?

Question

I want to do some kind of action according to the TableView Section Header Index Path. Is there any method to trace the section header Index Path?

Answer 1

Short Answer

There is no existing method for that.

Solution

Declare a section number variable in your custom header class.

class CustomHeader: UITableViewHeaderFooterView
{

//
// MARK :- PROPERTIES
//

var sectionNumber: Int!

//
// MARK :- METHODS
//

override func awakeFromNib()
{
    super.awakeFromNib()
    
    // Initialization code ...
}

func configureWith(_ section: Int)
{
    self.sectionNumber = section
}

} // end of class

Then in your view controller inside viewForHeaderInSection , assign section value while instantiating your custom header.

func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView?
{
    let header = tableView.dequeueReusableHeaderFooterView(withIdentifier: "selectHeaderIdentifier") as! CustomHeader
    header.configureWith(section)
    return header
}

Now, you have in your custom header a section number property, use it as you want :]

header.sectionNumber

Answer 2

how about func headerViewForSection ?

override func tableView(tableView: UITableView, headerViewForSection section: Int) -> UITableViewHeaderFooterView {

    let headerCell = tableView.dequeueReusableCellWithIdentifier("HeaderCell")        

    // do some stuf, e.g.
    switch (section) {
    case 0:
        headerCell.backgroundColor = UIColor.cyanColor()
    default:
        headerCell.backgroundColor = UIColor.redColor()
    }

    return headerCell
}
