如何使用單選按鈕隱藏表格視圖中的部分？

Question

在這裏，我在表格視圖中有四個部分，但在第一部分中，所有單元格都具有單選按鈕。每當它處於活動狀態時，我需要顯示剩餘的三個部分，如果不是，我需要隱藏剩餘的最後三個部分任何人都可以幫助我如何實現這一點？

圖片如下所示？

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

     } else{ 
      if(chekIndex == nil){ 
       self.checkIsRadioSelect.removeAll(keepingCapacity: false) 
       self.checkIsRadioSelect.append(sender.tag) 
       self.ProductTableView.reloadData() 
      } 
     } 
    } 

    func numberOfSections(in tableView: UITableView) -> Int{ 
    return 4 
    } 
    func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? { 
     if (section == 0){ 
      return "PAYMENT INFORMATION" 
     } 
     else if (section == 1){ 
      return "ORDER REVIEW" 
     } 
     else if (section == 2){ 
      return "PRODUCT" 
     } 
     else{ 
      return "" 
     } 
    } 
    func tableView(_ tableView: UITableView, willDisplayHeaderView view: UIView, forSection section: Int){ 
     let header = view as! UITableViewHeaderFooterView 
     header.textLabel?.textColor = UIColor.gray 
     header.textLabel?.textAlignment = NSTextAlignment.center 
     header.textLabel?.font = UIFont(name: "Futura", size: 17) 
    } 

    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int { 
     if (section == 0){ 
      return paymentmethodsArray.count 
     } 
     else if (section == 2) { 
      return productsDetails.count 
     } 
     else{

      myActivityIndicator.stopAnimating() 
      let arr = self.paymentmethodsArray[indexPath.row] 
      paymentcell.paymentNameLabel.text = arr["name"]as? String 
      paymentcell.radioButton.tag = indexPath.row 
      let checkIndex = self.checkIsRadioSelect.index(of: indexPath.row) 
      if(checkIndex != nil){ 
       paymentcell.radioButton.isSelected = true 
      }else{ 
       paymentcell.radioButton.isSelected = false 
      } 
      return paymentcell 
     } 
     else if (indexPath.section == 1){

      return shippingAddresscell 
     }

      let productNamecell = tableView.dequeueReusableCell(withIdentifier: "productNamecell",for:indexPath) as! ProductNameTableViewCell 
      let arr = productsDetails[indexPath.row] 
      let array = arr["product name"] as! String

      productNamecell.priceLabel.text = arr["Price"] as! String 
      productNamecell.QuantityLabel.text = String(describing: arr["Quantity"] as! Int) 
      productNamecell.subTotalLabel.text = arr["SubTotal"] as! String

     else{

      ordercell.subTotalLabel.text = subTotal

Answer 1

拿一個標誌（布爾我的意思是），它的初始值將是false。現在在單選按鈕的選擇集上它的值爲true。

現在，更改numberofSection方法。它將有條件地返回1或4。我的意思是如果你的國旗是true，那麼返回4否則1！而已！

Answer 2

這裏您需要根據條件更改numberOfSections方法。您不必將numberOfSections返回爲4，而需要根據單選按鈕選擇進行更改。 你可以保持一個布爾變量來檢查基於該返回按鈕是否被選中與否和基於像

func numberOfSections(in tableView: UITableView) -> Int{ 
let numberOfRows = ifRadioButtonSelected ? 4 : 1 
    return numberOfRows 
    } 

Answer 3

它的價值變化numberOfSections方法保持Bool變量來標識單選按鈕被選中或不count的number of section。

var isRadioButtonSelected = false 

@IBAction func selectRadioButton(_ sender: KGRadioButton) { 

    //Your remaining logic here. 

    //Based on the selection action you have to update the flag value. 
    if sender.isSelected { 
    isRadioButtonSelected = true 
    } else { 
    isRadioButtonSelected = false 
    } 

    // Reload table 
    self.ProductTableView.reloadData() 
} 

func numberOfSections(in tableView: UITableView) -> Int{ 
    if isRadioButtonSelected == true { 
     return 4 
    } else { 
     return 1 
    } 
    }
