单击导航栏外垂直对齐的栏按钮时出现问题

Question

我试图在我的UINavigationBar 的右侧垂直对齐两个UIBarButtonItems。我正在使用自定义视图，并在其中对齐两个按钮。

代码如下：

let rightBarButtonCustomView = UIView(frame: CGRect(x: 0, y: 0, width: 40, height: 90))
        
        let settingsButton = UIButton(frame: CGRect(x: 0, y: 0, width: 40, height: 40))
        settingsButton.setImage(UIImage(systemName: "gearshape.fill"), for: .normal)
        settingsButton.backgroundColor = preferredBackgroundColor
        settingsButton.tintColor = .accentColor
    
        settingsButton.addTarget(self, action: #selector(openSettingsScreen), for: .touchUpInside)
        settingsButton.layer.cornerRadius = settingsButton.frame.size.height / 2
        settingsButton.layer.borderWidth = 1
        settingsButton.layer.borderColor = UIColor.label.cgColor
        settingsButton.layer.masksToBounds = true
        
        rightBarButtonCustomView.addSubview(settingsButton)
        
        //NotificationButton
        let notificationsButton = UIButton(frame: CGRect(x: 0, y: 50, width: 40, height: 40))
        notificationsButton.setImage(UIImage(systemName: "bell.fill"), for: .normal)
        notificationsButton.backgroundColor = preferredBackgroundColor
        notificationsButton.tintColor = .accentColor

        notificationsButton.addTarget(self, action: #selector(openNotificationScreen), for: .touchUpInside)
        notificationsButton.layer.cornerRadius = notificationsButton.frame.size.height / 2
        notificationsButton.layer.borderWidth = 1
        notificationsButton.layer.borderColor = UIColor.label.cgColor
        notificationsButton.layer.masksToBounds = true
        
        rightBarButtonCustomView.addSubview(notificationsButton)
        
        self.navigationItem.rightBarButtonItem = UIBarButtonItem(customView: rightBarButtonCustomView)

这是它的样子：

不错吧？

嗯，问题是通知按钮没有收到点击，但设置按钮是。我的猜测是通知按钮在导航栏之外，如图（UINavigationBar是蓝色的，我的rightBarButtonCustomView是红色的）：

我尝试使用约束，增加导航栏的高度，但似乎没有任何效果。

任何帮助将不胜感激

谢谢！

下面的代码对我来说效果很好。

override func viewDidLayoutSubviews() {
    super.viewDidLayoutSubviews()
    navigationBar.frame = CGRect(x: 0, y: 0, width: view.frame.width, height: 200)
}
