iOS 15 导航栏透明问题

Question

在 iOS 15 中尝试透明的 NavigationBar，

它在低于 iOS 15 的版本中工作。

override func viewDidLoad() {
        // Clear the background image.
        self.navigationController?.navigationBar.setBackgroundImage(UIImage(), for: .default)
        // Clear the shadow image.
        self.navigationController?.navigationBar.shadowImage = UIImage()
        // Ensure the navigation bar is translucent.
        self.navigationController?.navigationBar.isTranslucent = true

        if #available(iOS 15, *) {
            let appearance = UINavigationBarAppearance()
            appearance.configureWithOpaqueBackground()
            appearance.shadowImage = UIImage()
            appearance.backgroundColor = .clear
            UINavigationBar.appearance().standardAppearance = appearance
            UINavigationBar.appearance().scrollEdgeAppearance = appearance
        }
}
