在导航控制器中时，视图控制器的首选状态栏样式被忽略

Preferred status bar style of view controller is ignored when in navigation controller(在导航控制器中时，视图控制器的首选状态栏样式被忽略)

问题描述

我正在编写一个具有多个视图的 iOS 应用程序.我已将 App 设置为使用基于 ViewController 的状态栏样式，这允许我使用以下代码

I'm writing an iOS App with multiple views. I've set the App to use ViewController-based status bar style, which allows me to use the following code

override var preferredStatusBarStyle: UIStatusBarStyle {
    return .lightContent
} 

效果如预期.

然后我将视图嵌入到导航控制器中，并将 BarButtonItem 与 showSegue 连接起来.从此视图的ViewController切换到忽略样式设置，默认显示黑色状态栏.

But then I've embedded the views in a navigation controller and connected a BarButtonItem with a showSegue. Since then the ViewController of the view switched to ignores the style settings and shows the default black status bar.

推荐答案

当你在一个不会被调用的导航控制器中时.导航控制器的 preferredStatusBarStyle 将被调用.与您的代码一起尝试:

When you're in a navigation controller that will not get called. The navigation controller's preferredStatusBarStyle will be called. Try this along with your code:

extension UINavigationController {

   open override var preferredStatusBarStyle: UIStatusBarStyle {
      return topViewController?.preferredStatusBarStyle ?? .default
   }
}
