How to get multiple buttons from a single tableViewcell?

I am making a quiz in a tableView that has 4 Buttons (options), I tagged them on a story board like 201,202,203,204 and got all of them successfully in tableView methods. But after adding targets to buttons, I am not able to get particular buttons in buttonClicked method.

func numberOfSectionsInTableView(tableView: UITableView) -> Int { return 1 }
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int { return questions.count }

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as UITableViewCell

    (cell.viewWithTag(100) as! UILabel).text = "Q : " + (questions[indexPath.row].objectForKey("MocQuestion")! as? String)!
    (cell.viewWithTag(100) as! UILabel).font = themeFont
    (cell.viewWithTag(101) as! UILabel).text = questions[indexPath.row].objectForKey("Op1")! as? String
    (cell.viewWithTag(102) as! UILabel).text = questions[indexPath.row].objectForKey("Op2")! as? String
    (cell.viewWithTag(103) as! UILabel).text = questions[indexPath.row].objectForKey("Op3")! as? String
    (cell.viewWithTag(104) as! UILabel).text = questions[indexPath.row].objectForKey("Op4")! as? String

    let btn1 = (cell.viewWithTag(201) as! UIButton)
    let btn2 = (cell.viewWithTag(202) as! UIButton)
    let btn3 = (cell.viewWithTag(203) as! UIButton)
    let btn4 = (cell.viewWithTag(204) as! UIButton)


//        btn1.tag = indexPath.row * 100 + 0
//        btn1.tag = indexPath.row * 100 + 1
//        btn1.tag = indexPath.row * 100 + 2
//        btn1.tag = indexPath.row * 100 + 3


    btn1.addTarget(self, action: #selector(Quiz.buttonClicked(_:)),forControlEvents: UIControlEvents.TouchUpInside)
    btn2.addTarget(self, action: #selector(Quiz.buttonClicked(_:)),forControlEvents: UIControlEvents.TouchUpInside)
    btn3.addTarget(self, action: #selector(Quiz.buttonClicked(_:)),forControlEvents: UIControlEvents.TouchUpInside)
    btn4.addTarget(self, action: #selector(Quiz.buttonClicked(_:)),forControlEvents: UIControlEvents.TouchUpInside)

    return cell
}

func buttonClicked(sender:UIButton)
{
    let tag = sender.tag
    print(tag)
}

In swift 3 You can try bellow like

  1. My table cell class

    class Custom_Cell: UITableViewCell {    

  @IBOutlet weak var ButtonA: UIButton!
  @IBOutlet weak var ButtonB: UIButton!
  @IBOutlet weak var ButtonC: UIButton!

 }

  2. Set Tag in table view 

      func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! Custom_Cell;



   cell.ButtonA.tag = indexPath.row;
   cell.ButtonB.tag = indexPath.row;
   cell.ButtonA.tag = indexPath.row;

    //Add Action Methods to UIButtons
     cell.ButtonA.addTarget(self, action: #selector(ButtonAAction), for: .touchUpInside)
    cell.ButtonB.addTarget(self, action: #selector(ButtonBAction), for: .touchUpInside)
    cell.ButtonA.addTarget(self, action: #selector(ButtonCAction), for: .touchUpInside)

   return cell;
}

  3. Button Action will look like ..

    func ButtonAAction(_ sender: Any)  {
   //Get Button cell position.
   let ButtonPosition = (sender as AnyObject).convert(CGPoint.zero, to: tableView)
   let indexPath = tableView.indexPathForRow(at: ButtonPosition)
   if indexPath != nil {


       print("Cell indexPath: \(indexPath?.row)")
    }
  }

In order to get every ques separate button click event you can pass the unique ID as postfix or prefix e.g 20101 or 01201 of every ques as a tag of button instead of hard-coded. Then get the tag and extract ques id first now proceed for examination as per ques.

If you want the indexPath to access the questions Array then you can try like this.

func buttonClicked(sender:UIButton) {
    let center = sender.center
    let point = sender.superview!.convertPoint(center, toView:self.tableView)
    let indexPath = self.tableView.indexPathForRowAtPoint(point)
    //Now you have tag of button check for that
    if (sender.tag == 201) {
        print("Option A")
    }
    else if (sender.tag == 202) {
        print("Option B")
    }
    else if (sender.tag == 203) {
        print("Option C")
    }
    else {
        print("Option D")
    }
    print(question[indexPath.row])
}
