Use the following code to get the complete text in text field inside should change characters:

 var str:NSString = textField.text! as NSString
 str = str.replacingCharacters(in: range, with: string) as NSString

For getting particular text field, you can set tag in cell for row and here you can check the text field tag to identify Text field.

In cell for row set:

    cell.textField.tag = indexPath.row

Then in should change characters in range

  array[textfield.tag] = str //which is the textfieldvalue

So here you can store text field value as per tableview row index.
