在自定义表视图单元格中添加自定义按钮，并且一次只能在Swift中选择一个单元按钮，任何人都可以为此提供帮助

Question

请查看我的自定义uitaiteView单元格代码，我面临问题，因为tableView dod dod dod dod select方法未调用。

我的代码在这里：

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCellWithIdentifier(self.cellIdentifier, forIndexPath: indexPath) as! DpMarginRptTableViewCell
    cell.selectionStyle = .None        
    if dataSource.count > 1
    {
        let dpMarginModel : DPSRDPDetailModel = self.dataSource.objectAtIndex(indexPath.row) as! DPSRDPDetailModel
        cell.scriptLabel.text = "(dpMarginModel.scripCode)"
        cell.dpQtyLabel.text = "(dpMarginModel.dpBalanceAC)"
        cell.haricutLabel.text = String(format: "%.2f",Float(dpMarginModel.valueAfterHairCut)/100) //"(dpMarginModel.valueAfterHairCut)"
        cell.transferTextfield.tag = indexPath.row
        cell.transferTextfield.text = "(dpMarginModel.transferText)"
        cell.transferTextfield.delegate = self
        cell.transferTextfield.layer.borderWidth = 1.0
        cell.transferTextfield.layer.borderColor = UIColor.blackColor().CGColor
        cell.radioButton1.tag = indexPath.row
        cell.radioButton1.addTarget(self, action: #selector(DpMarginView.buttonTapped(_:)), forControlEvents: .TouchUpInside)
        cell.radioButton1.setTitle(String.iconWithName(.radioUnchecked), forState: UIControlState.Normal)
        cell.radioButton1.setTitle(String.iconWithName(.radioChecked), forState: UIControlState.Selected)
   }
}

CustomTableViewCell类代码

class CustomTableViewCell : UITableViewCell {
   var screenWidth:CGFloat!
   var screenHeight:CGFloat!
   var radioButton1 : UIButton!
   var scriptLabel : UILabel!
   var dpQtyLabel:UILabel!
   var haricutLabel:UILabel!
   var transferTextfield: UITextField!
override init(style: UITableViewCellStyle, reuseIdentifier: String?)
{
    super.init(style: style, reuseIdentifier: reuseIdentifier)
    let screenSize:CGRect = UIScreen.mainScreen().bounds
    self.screenWidth = screenSize.width
    self.screenHeight = screenSize.height
    let boldFont = UIFont(name: "Helvetica Neue", size: 11)?.fontDescriptor().fontDescriptorWithSymbolicTraits(UIFontDescriptorSymbolicTraits.TraitBold)
    radioButton1 = UIButton(frame: CGRectMake(0, 5, 30, 40))
    radioButton1.tag = 101
    radioButton1.titleLabel?.font = UIFont(name: "Icomoon", size: 18)
    radioButton1.setTitleColor(UIColor.blackColor(), forState: UIControlState.Normal)
    radioButton1.setTitleColor(UIColor.blackColor(), forState: UIControlState.Selected)
    self.scriptLabel = UILabel.init(frame: CGRectMake(radioButton1.frame.size.width + 5, 5,(screenWidth/4) , 40))
    self.scriptLabel.textAlignment = .Left
    self.scriptLabel.font = UIFont(descriptor: boldFont!, size: 11)

    self.dpQtyLabel = UILabel.init(frame: CGRectMake(scriptLabel.frame.origin.x + scriptLabel.frame.size.width, 5, (screenWidth/4), 40))
    self.dpQtyLabel.textAlignment = .Left
    self.dpQtyLabel.font = UIFont(name: "HelveticaNeue", size: 11)

    self.haricutLabel = UILabel.init(frame: CGRectMake(dpQtyLabel.frame.origin.x + dpQtyLabel.frame.size.width, 5, (screenWidth/4), 40))
    self.haricutLabel.textAlignment = .Left
    self.haricutLabel.font = UIFont(name: "HelveticaNeue", size: 11)

    self.transferTextfield = UITextField.init(frame: CGRectMake((haricutLabel.frame.origin.x + haricutLabel.frame.size.width)-20, 5, (screenWidth/4) - 20, 40))
    self.transferTextfield.textAlignment = .Center
    self.transferTextfield.font = UIFont(name: "HelveticaNeue", size: 11)
    self.transferTextfield.keyboardType = .NumberPad
    self.contentView.addSubview(self.radioButton1)
    self.contentView.addSubview(self.scriptLabel)
    self.contentView.addSubview(self.dpQtyLabel)
    self.contentView.addSubview(self.haricutLabel)
    self.contentView.addSubview(self.transferTextfield)
    self.contentView.backgroundColor = UIColor.clearColor()
}

}

我想在自定义表视图单元格中添加自定义按钮，并且一次只能在Swift中选择一个单元按钮，任何人都可以帮助我吗？

请参阅此行 cell.radiobutton1.addtarget（self，action：#selector（dpmarginview.buttontapped（_ :)），forcontrolevents：.touchupinside）t在CellForrowatIndExpath中存在。相反，当您创建该按钮时，您应该将该行放入 customTableViewCell 中。并在CustomTableViewCell本身中调用 buttontapped 操作。

然后，您需要使用委托方法将消息传递给包含此tableView的UiviewVontroller。

因此，您的CustomTableViewCell会这样开始： -

    protocol CustomDelegate: class {
           func buttonTouchedAction()
        }
    class CustomTableViewCell : UITableViewCell {
        weak var delegate: CustomDelegate?
        var screenWidth:CGFloat!
        var screenHeight:CGFloat!
        .
        .
        .
}

在您的CellForrowatIndExpath中，而不是添加目标，而是使用此代码： -

cell.delegate = self

，在您的ViewController的底部添加此。我假设您的ViewController名称是CustomViewController： -

extension CustomViewController: CustomDelegate {
   fun buttonTouchedAction() {
      // Do your action here
   }
}

nb。为什么在将其更改为indexpath.row中的tableViewCell子类中的radiobutton1为101的标签。整个设置标签的东西在这里没有任何目的。
