Reload only one section header in UITableView

Viewed 14553

I'm using a custom cell as a section header in my UITableView. In that cell there are three buttons. If any of the buttons are clicked in that section's cell, it should reload that custom section cell only, not any rows. Is this possible?

I was using the following code to reload that cell:

tableViewHome.reloadSections([1], with: UITableViewRowAnimation.none)

It's hiding my section cell and distorting my entire table.

UPDATE

I'm using UITableView and following code I'm using:

func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {

        let cellHeader = tableViewHome.dequeueReusableCell(withIdentifier: "header") as! HeaderTableViewCell

        cellHeader.filter1btn.addTarget(self, action: #selector(filterBtnAction(_:)), for: .touchUpInside)
        cellHeader.filter2Btn.addTarget(self, action: #selector(filterBtnAction(_:)), for: .touchUpInside)
        cellHeader.filter3btn.addTarget(self, action: #selector(filterBtnAction(_:)), for: .touchUpInside)


        return cellHeader
    }


    @IBAction func filterBtnAction(_ sender: UIButton) {

        print(sender.tag)

        tableViewHome.reloadSections([1], with: UITableViewRowAnimation.none)

I think your header view class is extending UITableViewHeaderFooterView class. Add a function in the extension

extension UITableViewHeaderFooterView{
     func reloadHeaderCell(){
        preconditionFailure("This method must be overridden")
    }
}

Now override this in your Header class as below

class HeaderView: UITableViewHeaderFooterView {
   override func reloadHeaderCell() {
      ////// add your logic to reload view
    }
}

Now you can simply call below line to refresh views

self.tableView?.headerView(forSection:0)?.reloadHeaderCell()
