How to change the status bar background color and

Question

With the arrival of iOS 13 statusBar's view is no longer accessible trough:

value(forKey: "statusBar") as? UIView

Due to:

Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'App called -statusBar or -statusBarWindow on UIApplication: this code must be changed as there's no longer a status bar or status bar window. Use the statusBarManager object on the window scene instead.'

But it's not clear how it should be used for changing colours as keyWindow?.windowScene?.statusBarManager does not appear to contain anything related to it.

I'm compiling my code with (iOS 10, *) compatibility, so I intend to continue using UIKit.

Any ideas regarding this subject?

Answer 1

if (@available(iOS 13, *))
{    
    UIView *statusBar = [[UIView alloc]initWithFrame:[UIApplication sharedApplication].keyWindow.windowScene.statusBarManager.statusBarFrame] ;
    statusBar.backgroundColor = [UIColor redColor];
    [[UIApplication sharedApplication].keyWindow addSubview:statusBar];

 }

this is an ObjC version of most voted answer for those like me who are still using it:

create a category of UIApplication and add it to your project:

@implementation UIApplication (iOS13PorcoDiDio)

- (UIView*) statusBar
{

    if([UIDevice getOSVersion] >= 13)
    {

        const NSUInteger k_TAG_STATUSBAR = 38482458385;

        UIView * vStatusBar = [[UIApplication sharedApplication].keyWindow viewWithTag:k_TAG_STATUSBAR];
        if(vStatusBar != nil)

            return vStatusBar;

        else {

            UIView *vStatusBar = [[UIView alloc] initWithFrame:[UIApplication sharedApplication].statusBarFrame];
            [vStatusBar setTag:k_TAG_STATUSBAR];
            [[UIApplication sharedApplication].keyWindow addSubview:vStatusBar];

            return vStatusBar;

        }

    } else if([UIApplication respondsToSelector:@selector(statusBar)])

        return (UIView*)[UIApplication sharedApplication].statusBar;

    else

        return nil;


}

@end

This worked for me in Swift 5

   override func viewDidLoad() {
      super.viewDidLoad()

      if #available(iOS 13, *)
      {
          let statusBar = UIView(frame: (UIApplication.shared.keyWindow?.windowScene?.statusBarManager?.statusBarFrame)!)
          statusBar.backgroundColor = #colorLiteral(red: 0.2346, green: 0.3456, blue: 0.5677, alpha: 1)
          UIApplication.shared.keyWindow?.addSubview(statusBar)
      } else {
         // ADD THE STATUS BAR AND SET A CUSTOM COLOR
         let statusBar: UIView = UIApplication.shared.value(forKey: "statusBar") as! UIView
         if statusBar.responds(to:#selector(setter: UIView.backgroundColor)) {
            statusBar.backgroundColor = #colorLiteral(red: 0.2346, green: 0.3456, blue: 0.5677, alpha: 1)
         }
         UIApplication.shared.statusBarStyle = .lightContent
      }
   }

This is the best answer I have ever seen.. Cheers

    if #available(iOS 13.0, *) {
    let app = UIApplication.shared
    let statusBarHeight: CGFloat = app.statusBarFrame.size.height

    let statusbarView = UIView()
        statusbarView.backgroundColor = ColorPalette.grayChateau  
    view.addSubview(statusbarView)

    statusbarView.translatesAutoresizingMaskIntoConstraints = false
    statusbarView.heightAnchor
        .constraint(equalToConstant: statusBarHeight).isActive = true
    statusbarView.widthAnchor
        .constraint(equalTo: view.widthAnchor, multiplier: 1.0).isActive = true
    statusbarView.topAnchor
        .constraint(equalTo: view.topAnchor).isActive = true
    statusbarView.centerXAnchor
        .constraint(equalTo: view.centerXAnchor).isActive = true

} else {
    let statusBar = UIApplication.shared.value(forKeyPath: "statusBarWindow.statusBar") as? UIView
    statusBar?.backgroundColor = UIColor.red
 }

You can add some conditions or use first one. Just create some extension for UIApplication.

extension UIApplication {
var statusBarUIView: UIView? {
    if #available(iOS 13.0, *) {
        let tag = 38482
        let keyWindow = UIApplication.shared.windows.filter {$0.isKeyWindow}.first

        if let statusBar = keyWindow?.viewWithTag(tag) {
            return statusBar
        } else {
            guard let statusBarFrame = keyWindow?.windowScene?.statusBarManager?.statusBarFrame else { return nil }
            let statusBarView = UIView(frame: statusBarFrame)
            statusBarView.tag = tag
            keyWindow?.addSubview(statusBarView)
            return statusBarView
        }
    } else if responds(to: Selector(("statusBar"))) {
        return value(forKey: "statusBar") as? UIView
    } else {
        return nil
    }
  }
}

UPDATED: Sorry, I don't have enough time to test it in real projects, but it works in "Hello world" app. You can read more info about keyWindow and statusBarFrame in order to make it better.

extension UIApplication {
var statusBarUIView: UIView? {

    if #available(iOS 13.0, *) {
        let tag = 3848245

        let keyWindow = UIApplication.shared.connectedScenes
            .map({$0 as? UIWindowScene})
            .compactMap({$0})
            .first?.windows.first

        if let statusBar = keyWindow?.viewWithTag(tag) {
            return statusBar
        } else {
            let height = keyWindow?.windowScene?.statusBarManager?.statusBarFrame ?? .zero
            let statusBarView = UIView(frame: height)
            statusBarView.tag = tag
            statusBarView.layer.zPosition = 999999

            keyWindow?.addSubview(statusBarView)
            return statusBarView
        }

    } else {

        if responds(to: Selector(("statusBar"))) {
            return value(forKey: "statusBar") as? UIView
        }
    }
    return nil
  }
}

I have encountered this issue before. My application got crash while I run this code using XCode 11 and Swift 5.0.

Previous Code:-

UIApplication.shared.statusBarView?.backgroundColor = UIColor.init(red: 243/250, green: 243/250, blue: 243/250, alpha: 1)

Just Changed to:-

if #available(iOS 13.0, *) {
    let statusBar = UIView(frame: UIApplication.shared.keyWindow?.windowScene?.statusBarManager?.statusBarFrame ?? CGRect.zero)
     statusBar.backgroundColor = UIColor.init(red: 243/250, green: 243/250, blue: 243/250, alpha: 1)
     UIApplication.shared.keyWindow?.addSubview(statusBar)
} else {
     UIApplication.shared.statusBarView?.backgroundColor = UIColor.init(red: 243/250, green: 243/250, blue: 243/250, alpha: 1)
}

Now my problem solved. Happy coding.
