如何使用自定义复选框按钮选择表视图行选择？

如何使用自定义按钮选择表格视图行。我有另一个按钮，称为选择表视图外部的所有内容，我的问题是，在单击表视图按钮外部时，如何选择和取消选择表视图内部的行？同时我可以在表视图中选择单行吗？如何在 swift 3 中做到这一点？这是我在 cellforrow 方法中的代码

 func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {


    let identifier = "Custom"
    var cell: TStudentAttendanceCell! = tableView.dequeueReusableCell(withIdentifier: identifier) as? TStudentAttendanceCell
    if cell == nil {
        tableView.register(UINib(nibName: "TStudentAttendanceCell", bundle: nil), forCellReuseIdentifier: identifier)
        cell = tableView.dequeueReusableCell(withIdentifier: identifier) as? TStudentAttendanceCell
    }
    print("studentAttendanvceArray--",studentAttendanceArray.object(at: indexPath.row) )
    var localDic :NSDictionary!

    localDic = studentAttendanceArray.object(at: indexPath.row) as! NSDictionary

    Common.sharedInstance.StopActivity()        
    cell.profile_img.image = self.image
    cell.name_lbl.text = localDic["student_name"] as? String
    cell.selectionStyle = UITableViewCellSelectionStyle.none
    cell.contentView.backgroundColor = UIColor.clear
    let whiteRoundedView : UIView = UIView(frame: CGRect(x: 10, y: 8, width: self.view.frame.size.width - 20, height: 90))

    whiteRoundedView.layer.backgroundColor = CGColor(colorSpace: CGColorSpaceCreateDeviceRGB(), components: [1.0, 1.0, 1.0, 0.9])
    whiteRoundedView.layer.masksToBounds = false
    whiteRoundedView.layer.cornerRadius = 2.0
    whiteRoundedView.layer.shadowOffset = CGSize(width: -1, height: 1)
    whiteRoundedView.layer.shadowOpacity = 0.2
    cell.contentView.addSubview(whiteRoundedView)
    cell.contentView.sendSubview(toBack: whiteRoundedView)

    return cell

}

视图控制器

class ViewController: UIViewController,UITableViewDelegate, UITableViewDataSource {

  @IBOutlet var tableView: UITableView!
  var allStudentsArr:[[String:String]] = []
  var selectedRows:[IndexPath] = []


  override func viewDidLoad() {
    super.viewDidLoad()
    tableView.allowsSelection = false
    allStudentsArr = [["name":"name1"],["name":"name2"],["name":"name3"],["name":"name4"],["name":"name5"],["name":"name6"],["name":"name7"],["name":"name8"]]
  }
  func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return allStudentsArr.count
  }

  func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "Cell") as! CustomTableViewCell
    cell.nameLbl.text = allStudentsArr[indexPath.row]["name"]
    if selectedRows.contains(indexPath)
    {
      cell.checkBox.setImage(UIImage(named:"selected"), for: .normal)
    }
    else
    {
      cell.checkBox.setImage(UIImage(named:"unselected"), for: .normal)
    }
    cell.checkBox.tag = indexPath.row
    cell.checkBox.addTarget(self, action: #selector(checkBoxSelection(_:)), for: .touchUpInside)
    return cell
  }
  @objc func checkBoxSelection(_ sender:UIButton)
  {
    let selectedIndexPath = IndexPath(row: sender.tag, section: 0)
    if self.selectedRows.contains(selectedIndexPath)
    {
      self.selectedRows.remove(at: self.selectedRows.index(of: selectedIndexPath)!)
    }
    else
    {
      self.selectedRows.append(selectedIndexPath)
    }
    self.tableView.reloadData()
  }
  @IBAction func selectAllBtnAction(_ sender: UIBarButtonItem) {
    self.selectedRows = getAllIndexPaths()
    self.tableView.reloadData()
  }

  func getAllIndexPaths() -> [IndexPath] {
    var indexPaths: [IndexPath] = []
      for j in 0..<tableView.numberOfRows(inSection: 0) {
        indexPaths.append(IndexPath(row: j, section: 0))
      }
        return indexPaths
  }
}
