TableViewCell Multiple Editext value repeated during scrolling - ios

Question

I have tableview with three edittext in each section of cell lies side by side.I want to give input from user interface and after giving all values while i click on Button some mathematical calculation will be done to give result.
But edittext value is getting repeated while scrolling table view.Here is my code snippet.
import UIKit
class Density_Price_Calculation_TableView: UIViewController , UITableViewDelegate , UITableViewDataSource {
#IBOutlet weak var Density_Price_Calculation_TableView: UITableView!
#IBOutlet weak var Gravity: UILabel!
#IBOutlet weak var Price: UILabel!
var phreditText = [String]()
var densityeditText = [String]()
var priceeditText = [String]()
var ArrayOfCell = [Density_Price_Calculation_TableViewCell]()
override func viewDidLoad() {
super.viewDidLoad()
Density_Price_Calculation_TableView.delegate = self
Density_Price_Calculation_TableView.dataSource = self
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return Density_Price_Chemicals_MasterData.instance.getChemical_Names().count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell : Density_Price_Calculation_TableViewCell = tableView.dequeueReusableCell(withIdentifier: "density_price_calculation_cell", for: indexPath) as! Density_Price_Calculation_TableViewCell
let chemical_names = Density_Price_Chemicals_MasterData.instance.getChemical_Names()[indexPath.row]
cell.updateViews(chemical_names: chemical_names)
ArrayOfCell.append(cell)
return cell
}
#IBAction func btn_pressed(_ sender: UIButton) {
var totalSize=0.00, gravity=0.0,price=0.0
for cell in ArrayOfCell
{
totalSize=totalSize + (Double(cell.phreditText.text ?? "") ?? 0)
let tempPhr=Double(cell.phreditText.text ?? "") ?? 0
let tempDen=Double(cell.densityeditText.text ?? "") ?? 0
let tempPrice=Double(cell.priceeditText.text ?? "") ?? 0
if(tempPhr != 0 && tempDen != 0)
{
gravity=gravity + tempPhr/tempDen
}
price = price + (tempPhr*tempPrice)
}
Gravity.text = String (format : "%.3f",(Double(totalSize/gravity)))
Price.text = String (format : "%.3f",(Double(price/totalSize)))
}
}
My TableviewCell Content
import UIKit
class Density_Price_Calculation_TableViewCell: UITableViewCell {
#IBOutlet weak var chemical_name: UILabel!
#IBOutlet weak var phreditText: UITextField!
#IBOutlet weak var densityeditText: UITextField!
#IBOutlet weak var priceeditText: UITextField!
func updateViews(chemical_names:Density_Price_Calculation) {
chemical_name.text = chemical_names.chemical_name
}
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
// Dismiss the keyboard when the view is tapped on
phreditText.resignFirstResponder()
densityeditText.resignFirstResponder()
priceeditText.resignFirstResponder()
}
}
TableView Each Cell Content Image for referrence
Thanks in Advance.

Answer 1

This could be because you are dequeuing the table view cell in cellForRowAt and maintaining the same in the ArrayOfCell and due to dequeue reference this issue could have occurred.
So try the following changes,
Instead of
let cell : Density_Price_Calculation_TableViewCell = tableView.dequeueReusableCell(withIdentifier: "density_price_calculation_cell", for: indexPath) as! Density_Price_Calculation_TableViewCell
Try using,
let cell = Density_Price_Calculation_TableViewCell(style: .default, reuseIdentifier: "density_price_calculation_cell")
Note*
- This process could be little performance intensive since we are not dequeuing the cell.
