uinavigationcontroller - 自定义UINavigationBar可以工作，只有一个ViewController除外(Customizing UINavigationBar works except only one ViewController)

Question

I customized UINavigationBar globally in AppDelegate.

(我在AppDelegate中全局自定义了UINavigationBar。)

let appearance = UINavigationBar.appearance()
appearance.barTintColor = My Color
appearance.tintColor = UIColor.white
appearance.isTranslucent = false
let textAttributes = [NSAttributedString.Key.foregroundColor: UIColor.white,
                      NSAttributedString.Key.font: My Font]
appearance.titleTextAttributes = textAttributes as [NSAttributedString.Key : Any]

UIBarButtonItem.appearance().setTitleTextAttributes (
        [
            NSAttributedString.Key.font: My Font,
            NSAttributedString.Key.foregroundColor: UIColor.white
        ], for: .normal)

UILabel.appearance(whenContainedInInstancesOf: [UIAlertController.self]).numberOfLines = 0

It works great on every viewController as shown below.

(如下所示，它在每个viewController上都很好用。)

But only one viewController shows different appearance as shown below.

(但是只有一个viewController会显示不同的外观，如下所示。)

This viewController is pushed by another viewController which is embed in UINavigation Controller.

(该viewController由嵌入在UINavigation Controller中的另一个viewController推动。)

I have many other viewControllers that is pushed like this way and all they work as expected.

(我还有许多其他以这种方式推送的viewControllers，它们均按预期工作。)

I see no differences in the way I implemented this viewController.

(我看不到实现此viewController的方式的差异。)

Deleting this VC, presenting VC, navigationVC and re-creating them all didn't work.

(删除此VC，显示VC，navigationVC并重新创建它们均无效。)

Anyone has this kind of issue?

(有人遇到这种问题吗？)
