Swift 3.0 TableView单元格按钮

Question

我在tableview单元格上设置了一个按钮,我想知道如何操作它.也就是说,我有兴趣更改按钮的名称标题,并在单击按钮时添加另一个目标(按钮的不同功能).我的想法是需要将它添加到buttonClicked func中,但我不确定如何引用被单击的特定cellForRow.或许可以在cellForRow中使用条件来确定按钮标题是什么？我不太清楚最好的办法是什么.

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

    let button : UIButton = UIButton(type:UIButtonType.custom) as UIButton

    button.frame = CGRect(origin: CGPoint(x: 200,y :60), size: CGSize(width: 100, height: 24))
    let cellHeight: CGFloat = 44.0
    button.center = CGPoint(x: view.bounds.width / (4/3), y: cellHeight / 2.0)


    button.setTitleColor(.blue, for: .normal)
    button.addTarget(self, action: #selector(buttonClicked), for: UIControlEvents.touchUpInside)
    button.setTitle("Add", for: UIControlState.normal)

    cell.addSubview(button)


    return cell
}

func buttonClicked(sender : UIButton!) {
    print("Added!")


}

Answer 1

对于Swift 3.2和4.0

找到" indexPath.row"和" indexPath.section"

//在"cellForRowAt"按钮上添加目标

cell.myBtn.addTarget(self, action: #selector(self.btnAction(_:)), for: .touchUpInside)

//添加功能

func btnAction(_ sender: UIButton) {

    let point = sender.convert(CGPoint.zero, to: yourTableView as UIView)
    let indexPath: IndexPath! = yourTableView.indexPathForRow(at: point)

    print("row is = \(indexPath.row) && section is = \(indexPath.section)")
}

Answer 2

更改和添加您的代码

    button.addTarget(self, action:#selector(YourViewController.buttonClicked(_:)), for: .touchUpInside)

    button.tag = indexPath.row



func buttonClicked(sender : UIButton!) {
    print("Added!")
     let row = sender.tag;
    print(row)

}
