Swift UIbutton inside tableviewCell tp perform segue is not working

I have a custom tableviewcell and I have button inside the cell when I click on the button the next viewcontroller does not show he content , but if I click on cell then clicking the button the next view controller showing the right content here is my code : 

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "reuseIdentifier", for: indexPath) as! TableViewCell
    cell.label.text = numberArray[indexPath.row]
 cell.button.tag = indexPath.row

    cell.button.addTarget(self,action:#selector(TableViewController.someAction(sender:)),
                          for:.touchUpInside)
    return cell
}

here is my button action :

func someAction(sender : UIButton){

self.performSegue(withIdentifier: "showDetail", sender: self)

}

and here is my segue function : 

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {


        if segue.identifier == "showDetail" {

            if let indexPath = tableView.indexPathForSelectedRow
            {
                (segue.destination as! ViewController).number = numberArray[indexPath.row]

            }

        }
    }

The issue is that in prepare(for:sender:) you are getting indexPath using indexPathForSelectedRow now if you directly click the button then cell with not selected what you need is to pass the indexPath of cell with performSegue(withIdentifier:sender:).

func someAction(sender:  UIButton) {
    let point = sender.superview?.convert(sender.center, to: self.tableView)
    if let indexPath = self.tableView.indexPathForRow(at: point!) {
        //pass indexPath as sender with performSegue
        self.performSegue(withIdentifier: "showDetail", sender: indexPath)
    }
}

Now in prepare(for:sender:) cast the sender to indexPath and you all good to go.

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
    if segue.identifier == "showDetail" {
        if let indexPath = sender as? IndexPath
        {
            (segue.destination as! ViewController).number = numberArray[indexPath.row]
        }
    }
}

Note: It is batter if you ignored to use tag.

Try this: 

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {


            if segue.identifier == "showDetail" {


                    (segue.destination as! ViewController).number = numberArray[sender.tag]

                }

        }

You have to use custom cell and follow the steps:

  • add action and outlet in the custom cell from the storyboard.
  • After that, you have to add protocol methods in the custom cell( custom delegate method).
  • and use these methods in your view controller. and add functionality for show detail.
