如何在暗模式下单击按钮时使状态栏文本颜色变暗？

Question

When I click on Default button status bar style changes .black in Normal mode But when I enable Dark Mode , status bar automatically becomes white and won't change back

I put the separate code to change it again but it won't work

Here is my code

@objc func defaultbutton()
{
    if #available(iOS 13.0, *)
    {
        if traitCollection.userInterfaceStyle == .dark
        {
            self.setNeedsStatusBarAppearanceUpdate()
            self.navigationController?.navigationBar.barStyle = .black                               
            print("status bar style changing is failing everytime it's enterng here")
        }
        else
        {
            self.navigationController!.navigationBar.barStyle = .default
        }
    }
 }

You can override preferredStatusBarStyle property in your viewController to change your status bar color to dark in dark mode.

override  open var preferredStatusBarStyle: UIStatusBarStyle {
    get {
        if traitCollection.userInterfaceStyle == .dark {
            return UIStatusBarStyle.darkContent
        } else {
            return UIStatusBarStyle.default
        }
    }
}
