UITableView没有在屏幕上显示所有内容

Question

我有一个包含3个部分的UITableView，但是第3个部分未显示所有内容。在本部分中，我必须永远无限地添加项目，但屏幕不会显示所有内容。

我的故事板：

工作方式：

数据源委托：

func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
        if indexPath.section == 2 {
            return tableView.rowHeight
        }
        return 44
    }

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
            if indexPath.section == 0 {
                // Section options customer
                let cell = tableView.dequeueReusableCell(withIdentifier: "CellSelectionCreateSale") as! CellSelectionCreateSale

                switch indexPath.row {

                case 0: // Cliente
                    cell.lblField.text = "Cliente"
                    let tapSelectCustomer = UITapGestureRecognizer(target: self, action: #selector(handlerSelectCustomer))
                    cell.lblOptionSelect.addGestureRecognizer(tapSelectCustomer)
                    break

                case 1: // Main Addr
                    cell.lblField.text = "Endereço Principal"
                    break

                case 2: // Invoice Addr
                    cell.lblField.text = "Endereço de Cobrança"
                    break

                case 3: // Delivery Addr
                    cell.lblField.text = "Endereço de Entrega"
                    break

                    default: break
                }

                return cell
            } else if indexPath.section == 1 {
                // Section options order
                let cell = tableView.dequeueReusableCell(withIdentifier: "CellSelectionCreateSale") as! CellSelectionCreateSale

                switch indexPath.row {

                    case 0: // Create Date
                        cell.lblField.text = "Data do Pedido"
                        // let tapSelectOrderDate = UITapGestureRecognizer(target: self, action: #selector())
                        // Sera feito posteriormente

                    case 1: // Expiration Date
                        cell.lblField.text = "Data de Expiração"
                        let tapSelectExpirationDate = UITapGestureRecognizer(target: self, action: #selector(handleSelectDateExpiration))
                        cell.lblOptionSelect.addGestureRecognizer(tapSelectExpirationDate)

                        cell.lblOptionSelect.addGestureRecognizer(tapSelectPgto)
                        break

                    case 8:  // Due Date
                        let cell2 = tableView.dequeueReusableCell(withIdentifier: "CellSelectionCreateSale2") as! CellSelectionCreateSale2

在UITableView中有3种类型的单元格。但是只是第三节的单元格的高度不同。
