preferredStatusBarStyle在iOS 13上不适用 [英] preferredStatusBarStyle not respecting on iOS 13

问题描述

我正在模拟器中使用深色背景的单视图应用程序.这是一个包装在UINavigationController中的UIViewController.

I'm working in my simulator on a single view app with a dark background. It's a UIViewController wrapped in a UINavigationController.

在我的视图控制器中，我有override var preferredStatusBarStyle: UIStatusBarStyle { .lightContent }

In my view controller I have override var preferredStatusBarStyle: UIStatusBarStyle { .lightContent }

在我的info.plist中，我有View controller-based status bar appearance = YES

In my info.plist I have View controller-based status bar appearance = YES

但是，当我运行它时，它显示白色一秒钟，然后跳到显示黑色文本.

And yet when I run it it shows white for a second and then jumps to having black text.

这是怎么回事?有解决办法吗?

What's going on here? Is there a fix?

为确保没有任何作用，我已经尝试过.default，.lightContent和.darkContent

I've tried .default, .lightContent and .darkContent just to be sure, nothing works

推荐答案

我最近遇到了这个问题，这些扩展似乎可以解决此问题.

I recently ran into this problem and these extensions seemed to fix the issue.

extension UITabBarController {
    open override var childForStatusBarStyle: UIViewController? {
        return selectedViewController?.childForStatusBarStyle ?? selectedViewController
    }
}

extension UINavigationController {
    open override var childForStatusBarStyle: UIViewController? {
        return topViewController?.childForStatusBarStyle ?? topViewController
    }
}

我只是将它们放入名为UIViewController+StatusBar.swift的文件中，并将其包含在项目中.

I just put them into a file called UIViewController+StatusBar.swift and included it in the project.
