将UITapGestureRecognizer添加到tableViewCell的子视图中

Question

everyone, I am trying to add gesture recognizer to StackView which located on TableViewCell with that code and it doesn't work:

@IBOutlet var categoryStackView: UIStackView! {
    didSet {
        let tapGesture = UITapGestureRecognizer(target: self, action: #selector(categoryStackViewTapped))
        categoryStackView.addGestureRecognizer(tapGesture)
    }
}

And it doesn't work, I checked StackView and it is enable for user interactive

@objc func categoryStackViewTapped(sender: UITapGestureRecognizer) {
    print("Here we are")
}

I am suggesting another approach if you have multiple stackView in your tableView . Add the current index row as tag to your , and then add click action to your button handler function.

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "Cell") as! Cell
    cell.stackView.tag = indexPath.row
    cell.stackView.addTarget(self, action:#selector(categoryStackViewTapped(sender:)), for: .touchUpInside)

    return cell
}

Then in your handler function, you can get the correct index path by reading this tag

func categoryStackViewTapped(sender: UIStackView) {
    let myIndexPath = IndexPath(row: sender.tag, section: 0)
    //... other code here
}
