iOS 13 状态栏样式

Question

I want to change the status bar style on a per-ViewController level on iOS 13. So far I didn't have any luck.
I define UIUserInterfaceStyle as Light in info.plist (as I do not want to support dark mode) and set UIViewControllerBasedStatusBarAppearance to true . preferredStatusBarStyle is called on my ViewController but completely ignored. The UIUserInterfaceStyle seems to always override the VC preferences. How do I get per-ViewController status bar style working on iOS 13? Or is it not supported any more?

Answer 1

iOS 13.2, Swift 5.1

For me nothing worked from solutions mentioned before. After 5 hours I ended up on modalPresentationCapturesStatusBarAppearance flag .

    destinationNavigationController.modalPresentationCapturesStatusBarAppearance = true
    sourceViewController.present(destinationNavigationController, animated: animated, completion: nil)

After this preferredStatusBarStyle was called in presented VC.

override var preferredStatusBarStyle: UIStatusBarStyle {
    if #available(iOS 13.0, *) {
        if traitCollection.userInterfaceStyle == .light {
            return .darkContent
        } else {
            return .lightContent
        }
    } else {
        return .lightContent
    }
}

I had the same issue on iOS13 while it was fine on iOS12 for my app. I have a TabBarController which holds 3 NavigationBarControllers, and I present TabBarController from a previous ViewController. I fixed it by setting .modalPresentationStyle to .fullScreen when presenting:

tabbarController.modalPresentationStyle = .fullScreen

Maybe it will help you somehow...

In iOS13, there is now a .darkContent option for UIStatusBarStyle. For black text, use this (instead of .default) for preferredStatusBarStyle.

In my case, I had a similar issue with incorrect UIStatusBarStyle . For some view controllers in my app, I need to set a dark status bar style ignoring current system color mode. The problem was I used .default value, but in iOS 13 it changes depending on the context. That's why I added a small workaround to handle both iOS 12- and iOS 13+ cases.

private extension UIStatusBarStyle {

    static var darkContentWorkaround: UIStatusBarStyle {
        if #available(iOS 13.0, *) {
            return .darkContent
        } else {
            return .default
        }
    }

}

i had the same problem on iOS 13 while using navigation controller i was able to change the status bar color using

let navBarAppearance = UINavigationBarAppearance()

navigationBar.scrollEdgeAppearance = navBarAppearance

but the problem was when i was using present controller the status bar didn't change i used this code on top view controller

override func viewDidAppear(_ animated: Bool) {

    if #available(iOS 13, *)
    {
        let statusBar = UIView(frame: (UIApplication.shared.keyWindow?.windowScene?.statusBarManager?.statusBarFrame)!)
        statusBar.backgroundColor = UIColor.systemBackground
        UIApplication.shared.keyWindow?.addSubview(statusBar)
    }
}

you can use your color in "UIColor.systemBackground"
