    navigationController?.navigationBar.isTranslucent = true
}

override func viewDidLoad() {
    super.viewDidLoad()
    
    // 设置导航栏为透明
    navigationController?.navigationBar.isTranslucent = true
    
    // 添加右侧按钮项
    let rightButton = UIBarButtonItem(title: "按钮", style: .plain, target: self, action: #selector(buttonTapped))
