如何将自定义视图添加到上下文菜单iOS

let action = UIContextualAction(style: .normal, title: "自定义选项") { (action, view, completion) in
    // 执行自定义操作
    completion(true)
}

action.image = UIImage(named: "customIcon")
action.backgroundColor = .blue

let customView = UIView(frame: CGRect(x: 0, y: 0, width: 100, height: 50))
customView.backgroundColor = .green

action.handler = { (action, view, completion) in
    view.addSubview(customView)
    completion(true)
}

func tableView(_ tableView: UITableView, contextMenuConfigurationForRowAt indexPath: IndexPath, point: CGPoint) -> UIContextMenuConfiguration? {
    let configuration = UIContextMenuConfiguration(identifier: nil, previewProvider: nil) { (_) -> UIMenu? in
        let customMenu = UIMenu(title: "", children: [action])
        return customMenu
    }
    return configuration
}
