How to move right UIBarButtonItem next to largeTitle in UINavigationItem in iOS 13 (如何在largeTitle 13中将鼠标右移至UINavigationItem的旁边)

override func viewDidLoad() {
    super.viewDidLoad()

    let customButton = UIBarButtonItem(title: "Custom", style: .plain, target: self, action: #selector(customButtonTapped))
    navigationItem.rightBarButtonItem = customButton
}

@objc func customButtonTapped() {
    // 处理按钮点击事件
}

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)

    navigationController?.navigationBar.prefersLargeTitles = true
    navigationItem.largeTitleDisplayMode = .always
}

override func viewDidAppear(_ animated: Bool) {
    super.viewDidAppear(animated)

    if let navigationBar = navigationController?.navigationBar {
        for subview in navigationBar.subviews {
            if NSStringFromClass(subview.classForCoder) == "_UINavigationBarLargeTitleView" {
                subview.frame.origin.x = navigationBar.frame.width - subview.frame.width
            }
        }
    }
}
