Swift 3 如何在 UITableViewRowAction 中引用行索引

Question

所以我尝试在 TableView 中创建自定义滑动，包括删除和编辑按钮。但是，我无法引用我要编辑的所选单元格的行。本例中的索引为 [x, y]，其中 x 始终为 0，指的是滑动时编辑按钮的索引，而 y 是行索引。

如何引用行索引，换句话说，[x, y] 中的 y。谢谢!

override func tableView(_ tableView: UITableView, editActionsForRowAt: IndexPath) -> [UITableViewRowAction]? {
    let delete = UITableViewRowAction(style: .normal, title: "Delete") { action, index in
        self.leaveLeaveType.remove(at: index.row)
        self.leaveStartsTime.remove(at: index.row)
        self.leaveEndsTime.remove(at: index.row)
        self.leaveHost.remove(at: index.row)
        self.leaveDest.remove(at: index.row)
        tableView.deleteRows(at: [index], with: .fade)
    }

    let edit = UITableViewRowAction(style: .normal, title: "Edit") { action, index in
        //self.performSegue(withIdentifier: "editLeaveRequest", sender: self)
        let editCell = self.tableView.cellForRow(at: index)! as! LeaveRequestTableViewCell
        self.editLeaveType = editCell.leaveLeaveType.text!
        self.editHost = editCell.leaveHost.text!
        self.editDest = editCell.leaveDest.text!

        let cellDateTime = editCell.leaveDateTime.text!
        let startsTimeStartIndex = cellDateTime.index(cellDateTime.startIndex, offsetBy: 0)
        let startsTimeEndIndex = cellDateTime.index(cellDateTime.endIndex, offsetBy: -22)
        let startsTimeRange = startsTimeStartIndex..<startsTimeEndIndex
        self.editStartsTime = cellDateTime[startsTimeRange]

        let endsTimeStartIndex = cellDateTime.index(cellDateTime.startIndex, offsetBy: 22)
        let endsTimeEndIndex = cellDateTime.index(cellDateTime.endIndex, offsetBy: 0)
        let endsTimeRange = endsTimeStartIndex..<endsTimeEndIndex
        self.editEndsTime = cellDateTime[endsTimeRange]

    }

    delete.backgroundColor = .red
    edit.backgroundColor = .lightGray

    return [delete, edit]
}

代码无法工作，因为缺少本地参数标签 indexPath

override func tableView(_ tableView: UITableView, 
      editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? {...

此indexPath包含所选单元格的部分和行。
