如何从动态表格视图单元格 swift 获取按钮单击时的文本字段值

Question

So, I'm using dequeueReusableCell and will show several Table View with different row numbers of Current Price and and Change Price, depending on the product that I choose. How do I get the value of the text field from Label change 1, 2, 3 etc? Since it is a dynamic prototype, I do not know how to get the text field value when the Change Price button is clicked.

I have this class the connects the outlets

class priceListCell: UITableViewCell {
    // CURRENT PRICE
    @IBOutlet weak var lblProductNameCurrentPrice: UILabel!
    @IBOutlet weak var txtViewCurrentPrice: UITextView!

    // EDIT PRICE
    @IBOutlet weak var lblProductNameEditPrice: UILabel!
    @IBOutlet weak var txtFieldEditPrice: UITextField!
    @IBOutlet weak var btnChangePrice: UIButton!

}

And my TableView code is like this:

....
    case 1:
       if let editPriceCell = tableView.dequeueReusableCell(withIdentifier: "editPriceCell", for: indexPath) as? priceListCell {
       let product = editProducts[indexPath.row]
       editPriceCell.lblProductNameEditPrice.text = product.productName
       return editPriceCell
    }
    case 2:
       if let changePriceCell = tableView.dequeueReusableCell(withIdentifier: "changePriceCell", for: indexPath) as? priceListCell {
       return changePriceCell
    }

And here's my function to change price to firebase where i'm stuck at:

func changeValue() {
        for rowIndex in 0...self.tableView.numberOfRows(inSection: 3) {
            let indexPath = NSIndexPath(item: rowIndex, section: 3)

        }
    }

i'm stuck cause i don't know how to get the value of dynamic cell like this. Any help will be appreciated.

Thankyou

You need to get the cellForRow from UITableView and cast it as your class of UITableViewCell ie., priceListCell and then you can get your value from UITableViewCell , here's how:

func changeValue() {
    for rowIndex in 0..<tableView.numberOfRows(inSection: 3) {
        let indexPath = IndexPath(row: rowIndex, section: 3)
        if let editPriceCell = tableView.cellForRow(at: indexPath) as? priceListCell {
            print(editPriceCell.lblProductNameEditPrice.text)
        }
    }
}
