How to use UITableViewCell's accessoryButton as anchor for a Popover

I tried to use the accessoryButton of the UITableViewCell as the anchor of a Popover, but couldn't connect it using the storyboard. Programmatically I tried using the accessoryButtonTappedForRowWith function, this didn't work either. How can I connect it?

If your class is subclass of UITableViewController then use:

override func tableView(_ tableView: UITableView, accessoryButtonTappedForRowWith indexPath: IndexPath) {
    print(indexPath.row)
}

Check example code:

class ViewController: UITableViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

    }

    override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath)
        cell.textLabel?.text = "\(indexPath.row)"

        cell.accessoryType = UITableViewCellAccessoryType.detailButton
        return cell
    }

    override func tableView(_ tableView: UITableView, accessoryButtonTappedForRowWith indexPath: IndexPath) {
        print(indexPath.row)
    }

    override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return 10
    }
}

And if it's a subclass of UIViewController then you don't need override before that method so it will be:

func tableView(_ tableView: UITableView, accessoryButtonTappedForRowWith indexPath: IndexPath) {
    print(indexPath.row)
}

And don't forget to connect UITableViewDataSource and UITableViewDelegate of your table view with your ViewController in this case.
