【问题描述】：

这里我在启用单选按钮后有一个单选按钮，然后在选择删除特定单元格后会出现删除和编辑按钮，但前一行单选按钮启用了如何避免这种情况有任何帮助？

这里是这个的代码

  @IBAction func selectRadioButton(_ sender: KGRadioButton) 
        let chekIndex = self.checkIsRadioselect.index(of: sender.tag)
        _ = self.checkIsButtonEnable.index(of: sender.tag)
        if sender.isSelected 

         else
            if(chekIndex == nil)
                self.checkIsRadioSelect.removeAll(keepingCapacity: false)
                self.checkIsRadioSelect.append(sender.tag)
                self.checkIsButtonEnable.removeAll(keepingCapacity: false)
                self.checkIsButtonEnable.append(sender.tag)
                self.tableDetails.reloadData()
                self.addressSelected = true
                tableDetails.tableFooterView?.isHidden = false
                tableDetails.reloadData()
            
        
    
  func deleteAction(button: UIButton) 
        let buttonPosition = button.convert(CGPoint(), to: tableDetails)
        let index = tableDetails.indexPathForRow(at: buttonPosition)
        self.tableDetails.beginUpdates()
        shippingArray.remove(at:(index?.row)!)
        self.tableDetails.deleteRows(at: [index!], with: .top)
        self.tableDetails.endUpdates()
        tableDetails.tableFooterView?.isHidden = true
        self.addressSelected = false
        self.tableDetails.reloadData()
    
 func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell 
        if (indexPath.section == 0)
        
            let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! AddressTableViewCell
            tableDetails.isHidden = false
            myActivityIndicator.stopAnimating()
            let arr = shippingArray[indexPath.row]
            cell.deleteButton.tag = indexPath.row
            cell.nameLabel.text = arr["name"] as? String
            cell.addressLabel.text = arr["address"]as? String
            let mobilenumber : Any =  arr["number"] as AnyObject
            cell.mobileNumberLabel.text = "\(mobilenumber)"
            cell.radioButton.tag = indexPath.row
            cell.editButton.tag = indexPath.row
            cell.deleteButton.tag = indexPath.row
            cell.editButton.isHidden = true
            cell.deleteButton.isHidden = true
            cell.deleteButton.addTarget(self, action: #selector(deleteAction(button:)), for: .touchUpInside)
            let checkIndex = self.checkIsRadioSelect.index(of: indexPath.row)
            if(checkIndex != nil)
                cell.radioButton.isSelected = true
                cell.editButton.isHidden = false
                cell.deleteButton.isHidden = false
            
            else
            
                cell.radioButton.isSelected = false
                cell.editButton.isHidden = true
                cell.deleteButton.isHidden = true
            
            return cell
        

【问题讨论】：

您已经将标签值设置为删除按钮 -> cell.deleteButton.tag = indexPath.row in cellForRowAt。在您的删除方法中访问该标记值并使用 button.tag 值删除数组中的值

如何删除我不明白？ @AshwiniChougale

简单，当您删除行时，也会从所选数组中删除该索引。您正在从 indexpath.row(eg.3) 中删除数据并重新加载。所以基本上在删除 3 行队列刷新并且 (4 --> 3) 4 索引数据移动到 3 之后，你总共会少一个项目。

只是你需要做的-> shippingArray.remove(at:(button.tag))

【参考方案1】：

在删除方法中添加两行。

func deleteAction(button: UIButton) 
    let buttonPosition = button.convert(CGPoint(), to: tableDetails)
    let index = tableDetails.indexPathForRow(at: buttonPosition)
    self.tableDetails.beginUpdates()
    shippingArray.remove(at:(index?.row)!)
    self.tableDetails.deleteRows(at: [index!], with: .top)
    self.tableDetails.endUpdates()
    tableDetails.tableFooterView?.isHidden = true
    self.addressSelected = false

    **let checkIndex = self.checkIsRadioSelect.index(of: button.tag)
    self.checkIsRadioSelect.remove(at:checkIndex)**

    self.tableDetails.reloadData()
