我认为这是iOS 15+导航栏的默认行为。要防止这种情况，您可以在Storyboard中选择导航栏，然后在属性检查器中选择“标准和滚动边缘”，然后更改“标准外观”和“滚动边缘外观”部分的背景颜色，或查看此图片：
Storyboard配置
如果您想以编程方式执行此操作，可以在viewDidLoad中调用以下代码：
let appearance = UINavigationBarAppearance()
appearance.backgroundColor = .blue
navigationController?.navigationBar.standardAppearance = appearance
navigationController?.navigationBar.scrollEdgeAppearance = appearance
如果您希望全局执行此操作，可以在AppDelegate中调用以下代码：
let appearance = UINavigationBarAppearance()
appearance.backgroundColor = .red
UINavigationBar.appearance().standardAppearance = appearance
UINavigationBar.appearance().scrollEdgeAppearance = appearance
英文:
I think it's a default behavior for navigation bar in iOS 15+. To prevent this you can select navigation bar in storyboard and check Standard & Scroll Edge in attribute inspector, then change the background color in Standard Appearance and Scroll Edge Appearances section or see this image:
Storyboard configuration
If you want to do it programatically you can call this code in viewDidLoad:
let appearance = UINavigationBarAppearance()
appearance.backgroundColor = .blue
navigationController?.navigationBar.standardAppearance = appearance
navigationController?.navigationBar.scrollEdgeAppearance = appearance
If you want to do it globally you can call this code in AppDelegate:
let appearance = UINavigationBarAppearance()
appearance.backgroundColor = .red
UINavigationBar.appearance().standardAppearance = appearance
UINavigationBar.appearance().scrollEdgeAppearance = appearance
