How to access textview value which is inside tableview cell in swift 5?

Question

I have one viewcontroller, inside that I have one table view and 2 buttons save and cancel. In tableview cell i have one textview. after adding some text in textview i want to show that text. I am not sure how to get that tableview text on save button click. (number of rows may be dynamic).

    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

                if let cell = tableview.dequeueReusableCell(withIdentifier: "SummaryManualEditContentCell", for: indexPath) as? SummaryManualEditTableCell {


                    cell.txtAnswers.text = "enter text here"

                    return cell
                }
            return UITableViewCell()
        }

@IBAction func btnSave(_ sender: Any) {
        print("textviewText1 + textviewText2 + and so on ")
   }

In Addition to this on button click i want to add all that text multiple textviews into one string. is there any clean and best way to achieve this?

Thank you for helping!

You need to get the indexPath of the cell whose text you want to get get the cell for that indexpath like

@IBAction func btnSave(_ sender: Any) {
      let indexPath = IndexPath(row: 0, section: 0)
      if let cell = tableView.cellForRow(at: indexPath) as? SummaryManualEditTableCell {
        let text = cell.txtAnswers.text
        }
    }

And if you have multiple cells with textFields you can loop around to get all fields

  @IBAction func btnSave(_ sender: Any) {
var allTextViewsText = ""
       for i in 0...5{
          let indexPath = IndexPath(row: i, section: 0)
          if let cell = tableView.cellForRow(at: indexPath) as? SummaryManualEditTableCell {
            allTextViewsText += cell.txtAnswers.text
            }
        }
  print(allTextViewsText)
}

But keep it in mind that this approach only works in the case of visible cells otherwise for non visible cells you will get nil

I will suggest you to implement textView:shouldChange in each cell who has textView with a delegate to the tableView's viewController. When text is changed in the cell, delegate should propagate the change to the viewController which will save the value in a variable.

Then, when you press on the save button, you would simply take values from variables.
