如何更新基于UITableViewCell taps的UINavigationItem？

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    // 获取到被点击的UITableViewCell
    guard let cell = tableView.cellForRow(at: indexPath) else { return }
    
    // 根据UITableViewCell的标识符或数据模型，更新UINavigationItem
    if cell.reuseIdentifier == "Identifier1" {
        // 更新UINavigationItem的标题
        navigationItem.title = "新标题1"
        
        // 更新UINavigationItem的右侧按钮
        let rightButton = UIBarButtonItem(title: "按钮1", style: .plain, target: self, action: #selector(button1Tapped))
        navigationItem.rightBarButtonItem = rightButton
    } else if cell.reuseIdentifier == "Identifier2" {
        // 更新UINavigationItem的标题
        navigationItem.title = "新标题2"
        
        // 更新UINavigationItem的右侧按钮
        let rightButton = UIBarButtonItem(title: "按钮2", style: .plain, target: self, action: #selector(button2Tapped))
        navigationItem.rightBarButtonItem = rightButton
    }
}

@objc func button1Tapped() {
    // 按钮1的点击事件处理
}

@objc func button2Tapped() {
    // 按钮2的点击事件处理
}
