Save textField value to cell textLabel (name) [SWIFT] - ios

Question

I'm going to do something like this https://i.stack.imgur.com/jAGsk.png
So if user input points - it'll save points to the user's name. How to do it? I paste textField in the tableViewCell with a functions.
Here is code from the tableViewCell file
#IBOutlet weak var inputScore: UITextField!
public func configure(text: Int?, placeholder: String) {
inputScore.text = String(text!)
inputScore.placeholder = placeholder
inputScore.accessibilityValue = String(text!)
inputScore.accessibilityLabel = placeholder
}
And here is code from the VC file
public func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "InputScore") as! InputScoreTableViewCell
cell.textLabel?.text = usersIn[indexPath.row]
cell.configure(text: 100, placeholder: "Score")
return cell
}
public func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return usersIn.count
}
So how to save it to the user's name?

Answer 1

Use DidSelectRowAtIndexPath method to get cell textLable text in textField.
Below Sample Code for That:
import UIKit
class ViewController: UIViewController,UITableViewDelegate,UITableViewDataSource {
#IBOutlet var btnOK: UIButton!
#IBOutlet var txtValue: UITextField!
#IBOutlet var tblData: UITableView!
let arrResult = NSMutableArray()
override func viewDidLoad() {
super.viewDidLoad()
tblData.dataSource = self
tblData.delegate = self
btnOK.tag = 57775
btnOK.addTarget(self, action: #selector(applyEdit(sender:)), for: .touchUpInside)
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return arrResult.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = UITableViewCell(style: .default, reuseIdentifier: "cell")
cell.textLabel?.text = arrResult[indexPath.row] as? String ?? ""
return cell
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
btnOK.tag = indexPath.row
let cell: UITableViewCell = tableView.cellForRow(at: indexPath)!
txtValue.text = cell.textLabel?.text
setTitle()
}
func setTitle() {
if btnOK.tag == 57775 {
btnOK.setTitle("Add", for: .normal)
}else{
btnOK.setTitle("Update", for: .normal)
}
}
func applyEdit(sender: UIButton) {
if sender.tag == 57775 {
arrResult.add(txtValue.text ?? "")
}else{
arrResult.removeObject(at: sender.tag)
arrResult.insert(txtValue.text ?? "", at: sender.tag)
sender.tag = 57775
setTitle()
}
txtValue.text = ""
tblData.reloadData()
}
}
output:

You have to create a data model for your users:
class User: NSObject {
var points = 0
}
And then create an array of users in your view controller:
var users = [User]()
That way, you can do something like this
var user = users[indexPath.row]
user.points = 100
print(user.points) // 100
You can then display your users' points in your table view. You can also assign a tag to your text fields equal to the indexPath.row so that you can easily work with them.

In top of use user model provided by #Cesare we need to modified the cellForRowAtIndexPath method and your cell's implementation, adding a closure for data change event, and using it
#IBOutlet weak var inputScore: UITextField!
fileprivate var fnDataWasUpdated : (Int?) -> Void = {_ in} //closure for data change notification
public func configure(text: Int?, placeholder: String,_ fnListener: #escaping (Int?) -> Void) {
inputScore.text = String(text!)
inputScore.placeholder = placeholder
inputScore.accessibilityValue = String(text!)
inputScore.accessibilityLabel = placeholder
//added delegate implementation for UITextField
inputScore.delegate = self
self.fnDataWasUpdated = fnListener
}
also is needed that your cell adopts UITextFieldDelegate protocol
extension InputScoreTableViewCell : UITextFieldDelegate
{
func textFieldDidEndEditing(_ textField: UITextField)
{
if let intValue = Int(textField.text)
{
self.fnDataWasUpdated(intValue)
}
}
}
Finally we use the new closure in your cell
public func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "InputScore") as! InputScoreTableViewCell
let currUser = self.users[indexPath.row]
cell.configure(text: currUser.points, placeholder: "Score",{ (newIntValue) in
currUser.points = newIntValue
})
return cell
}
This code was not tested but I had been using the main concept in several projects, so if you have any kind of problems please let me know
I hope this helps you
