How to change the title of an UIAlertAction - ios

Question

How can I change the title of an UIAlertAction when I click the button ?
I want to click that button and from "Enable" to make it "Disable" for example.
I spent a lot of time trying to achieve this but I can't manage to do it.
Here is a small Demo with my issue: https://github.com/tygruletz/ChangeTitleOfAlertAction
Here is my code:
import UIKit
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
}
}
extension ViewController: UITableViewDelegate, UITableViewDataSource{
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 5
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
tableView.tableFooterView = UIView()
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath)
cell.textLabel?.text = "Row \(indexPath.row)"
return cell
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
showOptions()
}
func showOptions(){
var enable = "Enable"
let disable = "Disable"
let applyOn = UIAlertAction(title: enable, style: .default, handler: { (action: UIAlertAction!) in
enable = disable
})
let actionSheet = configureActionSheet()
actionSheet.addAction(applyOn)
self.present(actionSheet, animated: true, completion: nil)
}
func configureActionSheet() -> UIAlertController {
let actionSheet = UIAlertController(title: nil, message: nil, preferredStyle: .actionSheet)
let cancel = UIAlertAction(title: "Cancel", style: .cancel, handler: nil)
actionSheet.addAction(cancel)
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiom.pad ){
actionSheet.popoverPresentationController?.sourceView = self.view
actionSheet.popoverPresentationController?.sourceRect = CGRect(x: self.view.bounds.midX, y: self.view.bounds.midY, width: 0, height: 0)
actionSheet.popoverPresentationController?.permittedArrowDirections = []
}
return actionSheet
}
}
And here is a capture of screen:
Thank you if you try to help me !

Please follow below code:
Define property in your UIViewController
var selectedIndexPath:IndexPath!
Add argument in showOptions method
func showOptions(indexPath:IndexPath){
var status = "Enable"
if selectedIndexPath == indexPath{
status = "Disable"
}
let applyOn = UIAlertAction(title: status, style: .default, handler: { (action: UIAlertAction!) in
if self.selectedIndexPath == indexPath{
self.selectedIndexPath = nil
}else{
self.selectedIndexPath = indexPath
}
})
let actionSheet = configureActionSheet()
actionSheet.addAction(applyOn)
self.present(actionSheet, animated: true, completion: nil)
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
showOptions(indexPath: indexPath)
}
Note:
If you are going with this approach, Then you will never faced cell usability issue.
