表视图单元格内的按钮

在tableview单元格中,我需要两个按钮,一个用于接受,一个用于拒绝。

在xcode中,我将decline标记设置为2,accept标记设置为3。

在ViewController内部

  func accept(_ sender: UIButton){
   let buttonTag = sender.tag
    let point = sender.convert(CGPoint.zero, to: friendRequestTableView as UIView)
    let indexPath: IndexPath! = followerReqTableView.indexPathForRow(at: point)
    let user = requestsArray[indexPath.row]

  func decline(_ sender: UIButton){
    let buttonTag = sender.tag
    let point = sender.convert(CGPoint.zero, to: friendRequestTableView as UIView)
    let indexPath: IndexPath! = followerReqTableView.indexPathForRow(at: point)
    let user = requestsArray[indexPath.row]

}


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

    guard let cell = friendRequestTableView.dequeueReusableCell(withIdentifier: "FriendRequestTableViewCell") as? FriendRequestTableViewCell else { return UITableViewCell() }


    let user = requestsArray[indexPath.row]

    let image = cell.viewWithTag(1) as! UIImageView



    cell.confCell(///some user details)

    cell.decline.tag = 2
    cell.accept.tag = 3

    cell.decline.addTarget(self, action:#selector(self.decline(_:)), for: .touchUpInside)
    cell.decline.addTarget(self, action:#selector(self.accept(_:)), for: .touchUpInside)


    return cell

}

当我点击decline时,它同时调用两个函数-decline和accept,当我点击accept时,它什么都不做。 我哪里做错了?
