Passing parameter in selector (UIMenuController)

Question

I have a UIMenuController with a "Delete" menu item on top of a collection view cell which is displayed when the user long presses on a cell with section 1:

@IBAction func handleLongPressOnCell(_ sender: UILongPressGestureRecognizer) {
    let p = sender.location(in: collectionView)
    guard sender.state == .began, let indexPath = self.collectionView.indexPathForItem(at: p), let cell = self.collectionView.cellForItem(at: indexPath) else { return }

    if indexPath.section == 1 {
        let frameInSuperView = collectionView.convert(cell.frame, to: view)
        let deleteItem = UIMenuItem(title: "Delete", action: #selector(deleteCell))
        UIMenuController.shared.menuItems = [deleteItem]
        UIMenuController.shared.setTargetRect(frameInSuperView, in: view)
        becomeFirstResponder()
        UIMenuController.shared.setMenuVisible(true, animated: true)
    }
}

How do I pass the index path of the cell to the function below? I need this information to delete the object from the server.

@objc internal func deleteCell(sender: UIMenuItem) {
    print("delete menu item tapped! print index path of selected collection view cell?")
}

Answer 1

You cannot directly pass the info along with the selector action; instead you should store index path in a member variable which you set in your long-press handler and consume in your delete handler.

private var indexPathForDeleting: IndexPath? = nil

Don't forget to do your housekeeping and clear the variable when it's no longer needed.
