Status bar hidden in modal view (above full screen view)

try to hide the status bar from the modal view.

already check out several methods:

override func prefersStatusBarHidden() -> Bool { return true } with / without self.setNeedsStatusBarAppearanceUpdate()

and

 UIApplication.sharedApplication().setStatusBarHidden(true, withAnimation: .Fade)

but depreciates in iOS 9

this works in full screen (modal segue presentation option), but pay attention to the full screen, which is my setting.

if you have any ideas ..

To present a not full-screen view of the view controller, you need to use the modalPresentationCapturesStatusBarAppearance property.

eg.

 toViewController.modalTransitionStyle = .coverVertical toViewController.modalPresentationStyle = .overFullScreen toViewController.modalPresentationCapturesStatusBarAppearance = true fromViewController.present(toViewController, animated: true, completion: nil)

To present a full-screen view of a view controller, you need to:

  • install the new VC modalPresentationStyle .
  • override prefersStatusBarHidden in new VC
  • set app plist UIViewControllerBasedStatusBarAppearance to YES

eg.

 toViewController.modalTransitionStyle = .coverVertical toViewController.modalPresentationStyle = .fullScreen fromViewController.present(toViewController, animated: true, completion: nil)

(Yes, setting the status bar in iOS is unfortunate. It's no wonder that Qaru has so many questions on this and so many varied answers.)

Valid for updating the FullScreen status FullScreen automatically, but not for OverFullScreen .

Also, in my case, I needed to deal with the navigation controller on the stack in order to pass the ModalViewController as a child:

 extension UINavigationController { public override func childViewControllerForStatusBarHidden() -> UIViewController? { return self.visibleViewController } public override func childViewControllerForStatusBarStyle() -> UIViewController? { return self.visibleViewController } }

Inside ModalViewController we manually update the status bar to make it smooth, we have to do it in viewWillDisappear , but at this point visibleViewController still ModalViewController >, there is nothing left to use the internal status of boolBarHidden and update it accordingly.

 override func viewWillAppear(animated: Bool) { super.viewWillAppear(animated) self.statusBarHidden = true self.setNeedsStatusBarAppearanceUpdate() } override func viewWillDisappear(animated: Bool) { super.viewWillDisappear(animated) self.statusBarHidden = false self.setNeedsStatusBarAppearanceUpdate() } override func prefersStatusBarHidden() -> Bool { return self.statusBarHidden }

If you use a storyboard and want to hide / show the status bar, you can use this method on the previous view controller:

 override func prepare(for segue: UIStoryboardSegue, sender: Any?) { UIApplication.shared.setStatusBarHidden(false, with: UIStatusBarAnimation.none) }

To hide the status bar when executing a full-screen modal value, you need to set this in viewDidLoad:

 override func viewDidLoad() { super.viewDidLoad() modalPresentationCapturesStatusBarAppearance = true }

Then follow the standard method to hide the status bar:

 override var prefersStatusBarHidden: Bool { return true }
