如何从单个 uitableViewcell 获取多个按钮？

我正在做一个测验tableView有 4 个按钮（选项），我将它们标记在故事板上，例如 201,202,203,204，并成功地将它们全部放入tableView方法。但是将目标添加到按钮后，我无法在其中获取特定按钮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)
}

如果你想要indexPath访问问题Array那么你可以这样尝试。

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])
}
