确定按下了哪个表格视图单元格按钮？ [英] Identify in which table view Cell button was pressed?

问题描述

我有像测验一样的表视图单元格。在每个单元格中我都有一个按钮如何识别按下哪个单元格按钮。也许通过IndexPath ???
这是我连接按钮的方式

I have table view cells like quiz. And in each cell I have a buttons And how can I identify in which cell button was pressed. Maybe by IndexPath??? This is how I connected button to

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "QuestionCell")!
     variant1 = cell.contentView.viewWithTag(1) as! UIButton
     variant2 = cell.contentView.viewWithTag(2) as! UIButton
     variant3 = cell.contentView.viewWithTag(3) as! UIButton
     variant4 = cell.contentView.viewWithTag(4) as! UIButton

    variant1.addTarget(self, action: #selector(self.variant1ButtonPressed), for: .touchUpInside)
    variant2.addTarget(self, action: #selector(self.variant2ButtonPressed), for: .touchUpInside)
    variant3.addTarget(self, action: #selector(self.variant3ButtonPressed), for: .touchUpInside)
    variant4.addTarget(self, action: #selector(self.variant4ButtonPressed), for: .touchUpInside)

    return cell
}

func variant1ButtonPressed() {
    print("Variant1")
    variant1.backgroundColor = UIColor.green


}
func variant2ButtonPressed() {
    print("Variant2")
    variant2.backgroundColor = UIColor.green


}
func variant3ButtonPressed() {
    print("Variant3")
    variant3.backgroundColor = UIColor.green

}
func variant4ButtonPressed() {
    print("Variant4")
    variant4.backgroundColor = UIColor.green

}

这是故事板中的样子：

This is how it looks like in Storyboard:

推荐答案

使用此行获取indexPath，你必须在目标选择器上传递 UIButton

Use this line to get indexPath, Where you have to pass UIButton on target selector

func buttonTapped(_ sender:AnyObject) {
    let buttonPosition:CGPoint = sender.convert(CGPointZero, to:self.tableView)
    let indexPath = self.tableView.indexPathForRow(at: buttonPosition)
}
