iOS 13中的Bar Button色调颜色

Question

在iOS 13中，他们更改了导航栏颜色的操作方式。现在，他们将UINavigationBarAppearance与UIBarButtonItemAppearance一起使用，以自定义导航栏以及standardAppearance和scrollEdgeAppearance。

我正在寻找一种使standardAppearance和scrollEdgeAppearance具有不同的导航栏颜色的方法。或更改每种外观的条形按钮图标颜色的功能。

        //set the standard nav bar appearance
        let navBarAppearance = UINavigationBarAppearance()
        navBarAppearance.configureWithOpaqueBackground()
        navBarAppearance.titleTextAttributes = [.foregroundColor: UIColor.white]
        navBarAppearance.largeTitleTextAttributes = [.foregroundColor: UIColor.white]
        navBarAppearance.backgroundColor = UIColor.mainAppColorForNavBar

        //set bar button appearance
        let buttonAppearance = UIBarButtonItemAppearance()
        buttonAppearance.normal.titleTextAttributes = [.foregroundColor : UIColor.white]
        navBarAppearance.buttonAppearance = buttonAppearance

        UINavigationBar.appearance(whenContainedInInstancesOf: [UINavigationController.self]).standardAppearance = navBarAppearance



        //set the scroll edge nav bar appearance
        let scrollNavBarAppearance = UINavigationBarAppearance()
        scrollNavBarAppearance.configureWithOpaqueBackground()
        scrollNavBarAppearance.titleTextAttributes = [.foregroundColor: UIColor.label]
        scrollNavBarAppearance.largeTitleTextAttributes = [.foregroundColor: UIColor.label]

        //set bar button appearance
        let scrollButtonAppearance = UIBarButtonItemAppearance()
        scrollButtonAppearance.normal.titleTextAttributes = [.foregroundColor : UIColor.label]
        scrollNavBarAppearance.buttonAppearance = scrollButtonAppearance

        UINavigationBar.appearance(whenContainedInInstancesOf: [UINavigationController.self]).scrollEdgeAppearance = scrollNavBarAppearance

这将设置导航栏的颜色，但不会区分standardAppearance和scrollEdgeAppearance。

UINavigationBar.appearance().tintColor = UIColor.white

当前在scrollEdgeAppearance中（看起来像我想要的方式，不需要更改）

当前在standardAppearance中（按钮丢失，因为它与背景颜色相同，我想在standardAppearance中将图标颜色更改为白色）

感谢您的帮助。

谢谢
