ios - 如何在tableview单元格swift3中更改按钮背景颜色

Question

我有一个 UITableViewCell .在 TableViewCell 中，我在单行中有 7 个按钮。我想播放音乐。当我按下button1时，它的背景颜色应该改变。如果我按下 button2，它的背景颜色应该改变，并且 button1 将被取消选择。我还为每个按钮设置了标签，但我不明白，怎么办？声音播放正常，但我无法选择和取消选择按钮。我正在使用 swift3 .提前致谢。

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> tableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "PlayerCell") as! tableViewCell

     cell.Btn_one.addTarget(self, action: #selector(TableViewController.BtnAction_One), for: .touchUpInside)

     //For example
       if (cell.Btn_one.tag == 1){

        cell.Btn_one.backgroundColor = .white
    }else if (cell.Btn_two.tag == 2){
               cell.Btn_two.backgroundColor = .red
    }
 }


 @IBAction func BtnAction_One(_ sender: UIButton) {
    self.play()
 }

@Chetan 解决方案:第一个

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

    let btn1 = cell.viewWithTag(1) as! UIButton
    let btn2 = cell.viewWithTag(2) as! UIButton
    let btn3 = cell.viewWithTag(3) as! UIButton
    let btn4 = cell.viewWithTag(4) as! UIButton
    let btn5 = cell.viewWithTag(5) as! UIButton
    let btn6 = cell.viewWithTag(6) as! UIButton

    btn1.addTarget(self, action: #selector(btnClicked(sender:)), for: .touchUpInside)
    btn2.addTarget(self, action: #selector(btnClicked(sender:)), for: .touchUpInside)
    btn3.addTarget(self, action: #selector(btnClicked(sender:)), for: .touchUpInside)
    btn4.addTarget(self, action: #selector(btnClicked(sender:)), for: .touchUpInside)
    btn5.addTarget(self, action: #selector(btnClicked(sender:)), for: .touchUpInside)
    btn6.addTarget(self, action: #selector(btnClicked(sender:)), for: .touchUpInside)

    return cell
}

当这将 btnClicked
` func btnClickec(sender:UIButton){
sender.isSelected = true

    let cell = sender.superview?.superview as! UITableViewCell

    let btn1 = cell.viewWithTag(1) as! UIButton
    let btn2 = cell.viewWithTag(2) as! UIButton
    let btn3 = cell.viewWithTag(3) as! UIButton
    let btn4 = cell.viewWithTag(4) as! UIButton
    let btn5 = cell.viewWithTag(5) as! UIButton
    let btn6 = cell.viewWithTag(6) as! UIButton

    let arr = [btn1,btn2,btn3,btn4,btn5,btn6];

    for index in 0...5{
        let btn = arr[index]
        if index+1 == sender.tag{
            btn.isSelected = true
        }else{
            btn.isSelected = false
        }
    }
}

`

第二个:或者您也可以在 tableviewcell 中收集 View
