Swift tableview at delete cell process indexPath.row problem

Question

My question about tableview cell deleting process. When I try to delete cell with button, tableview first cell is deleted because of let indexPath = IndexPath(row: 0, section: 0) How can I delete clicked button's cell? I can't find any way to take clicked row. Can anyone help me?

    @objc func deleteAction() {


    let indexPath = IndexPath(row: 0, section: 0)
    _ = tableView.cellForRow(at: indexPath)
        if countPriceArray[indexPath.row] >= 1 {
            let ord = arraysForFiyat[indexPath.row]
            let splitOrd = ord.components(separatedBy: " ₺")
            let intOrd = splitOrd.map{ Int($0) ?? 0 }
            sum = sum - intOrd[0]
            UserDefaults.standard.set(arraysForUrun, forKey: "urunadi")
            UserDefaults.standard.set(arraysForFiyat, forKey: "urunfiyat")
            tableView.reloadData()

            if countPriceArray[indexPath.row] > 1 {
                countPriceArray[indexPath.row] -= 1
                tableView.reloadData()

            }else if countPriceArray[indexPath.row] == 1 {
                arraysForUrun.remove(at: indexPath.row)
                arraysForFiyat.remove(at: indexPath.row)
                countPriceArray.remove(at: indexPath.row)
                UserDefaults.standard.set(arraysForUrun, forKey: "urunadi")
                UserDefaults.standard.set(arraysForFiyat, forKey: "urunfiyat")
                tableView.deleteRows(at: [indexPath], with: .fade)

            }

        }
    }

Swift 5

In Tableview delegate Method cellForRowAt

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "CustomCell") as! CustomCell
        cell.btnAction.tag = indexPath.row
        cell.btnAction.addTarget(self, action: #selector(buttonActionClicked(sender:)), for: .touchUpInside)
        return cell
    }

Method of Button Action

@objc func buttonActionClicked(sender : UIButton) {
        let index = IndexPath(row: sender.tag, section: 0)
        print("Sender tag is :- \(sender.tag)")
    }

Note :- Add Tag to you button in indexpath and then try to use it for fetching indexpath of the selected button.

Be aware that this way causes unexpected behavior if cells can be inserted, deleted or moved. – vadian Sep 25 '19 at 14:25
@vadian I tried lots it seem working.. Why is this make this kind of behavior ? – eksglox Sep 25 '19 at 14:46

Because for example when a cell is inserted with `insertRows(at:` the method `cellForRowAt` is not necessarily called again for the other cells so the index path can change silently. – vadian Sep 25 '19 at 14:50
@vadian I understand now. Is there any way to fix that how can I call again cellForRowAt function? (when I try to add more items count will be change wrongly) – eksglox Sep 25 '19 at 15:56

A more reliable way is a callback closure, see this answer https://stackoverflow.com/questions/58098923/how-to-get-index-path-on-click-of-button-from-uitableview-in-swift-5/58100909#58100909 – vadian Sep 25 '19 at 16:51
