如何根据来自 Web 服务的数据启用单选按钮

Question

在这里，我实现了自定义设计，如图所示，我需要根据我的 Web 服务数据激活单选按钮。在 Web 服务中，我只收到一个键值对 0 和 1，如果它是 1，那么我需要激活单选按钮任何帮助如何实现？

这是我的单选按钮的代码

        @IBAction func selectRadioButton(_ sender: KGRadioButton) {
            let chekIndex = self.checkIsRadioSelect.index(of: sender.tag)
            let checkIndex = 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()
                }
            }
        }

这是表视图的代码

       let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! addressTableViewCell
                tableDetails.isHidden = false
                myActivityIndicator.stopAnimating()
                let arr = detailsArray[indexPath.row]
                cell.nameLabel.text = arr["name"]as? String
                cell.addressLabel.text = arr["address"]as? String
                let mobilenumber : Int =  arr["number"] as! Int
                cell.mobileNumberLabel.text = String(describing: mobilenumber)
                let defaultaddress : Int = arr["default"] as! Int
                cell.radioButton.tag = indexPath.row
                cell.editButton.tag = indexPath.row
                cell.deleteButton.tag = indexPath.row
                cell.editButton.isHidden = true
                cell.deleteButton.isHidden = true
                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

在您的cellForRowAtIndexPath方法中，更新如下所示的代码

我的建议是在重用tableView单元格时不要将indexPath.row设置为标签，它不会给你更好的结果。制作一些唯一的ID作为标签。或者做一些数学计算，用数字加/乘

。

 let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! addressTableViewCell
 tableDetails.isHidden = false
 myActivityIndicator.stopAnimating()
 let arr = detailsArray[indexPath.row]
 cell.nameLabel.text = arr["name"]as? String
 cell.addressLabel.text = arr["address"]as? String
 let mobilenumber : Int =  arr["number"] as! Int
 cell.mobileNumberLabel.text = String(describing: 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.radioButton.isSelected = false
 if let isDefault = arr["default"] as? Bool { // i think it won't be Integer it will be Bool,please debug & check it
          cell.radioButton.isSelected = isDefault 
          cell.editButton.isHidden = false
          cell.deleteButton.isHidden = false
 }
 let checkIndex = self.checkIsRadioSelect.index(of: indexPath.row)
     if(checkIndex != nil){
     cell.radioButton.isSelected = true
     cell.editButton.isHidden = false
     cell.deleteButton.isHidden = false
  }

更改下面的代码行。

let checkIndex = self.checkIsRadioSelect.index(of: indexPath.row) //delete this line
let checkIndex = arr["default"] as! Int //use radio button key.
@IBAction func selectRadioButton(_ sender: KGRadioButton) {
        let arr = detailsArray[sender.tag]
        if sender.isSelected {
            arr["default"] = @"0"
        } else{
            arr["default"] = @"1"
        }
        self.tableDetails.reloadData()
    }
