Can't Hide Status Bar in Avplayerviewcontroller's Portrait Mode

Can't hide status bar in AVPlayerViewController's portrait mode

Just figured out a solution:

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

    public override func childViewControllerForStatusBarStyle() -> UIViewController? {
        return self.childViewControllers.last
    }
}

Yup, just override those two functions for all Navigation View Controllers in your app. I consider this to be a hack and not the 'correct' solution to this problem, so use this with caution.

As far as I can tell, this should never fail. In my app, every Navigation VC has exactly one child VC, but YMMV.

StatusBar not adhering to the app's orientation and rotating

I ended up removing the above code in my root view controller and adding this into my app delegate. Status bar now stays put.

func application(application: UIApplication, supportedInterfaceOrientationsForWindow window: UIWindow?) -> UIInterfaceOrientationMask {
    if let vc = window?.rootViewController?.presentedViewController {
        if NSStringFromClass(vc.classForCoder) == "AVFullScreenViewController" {
            return UIInterfaceOrientationMask.AllButUpsideDown
        }
    }
    return UIInterfaceOrientationMask.Portrait
}

iOS 14 display status bar in landscape

Your code is correct (this is all you need in a new vanilla iOS app project):

override var prefersStatusBarHidden: Bool {
    return false
}

The problem is that this works only up through iOS 12. In iOS 13 and later, the runtime stopped interpreting a value of false to allow you to override the hiding of the status bar in landscape on an iPhone. Similarly, calling application.setStatusBarHidden fails to show the status in landscape.

This is probably a side effect of the UIWindowScene architecture that was introduced in iOS 13. Or it might be intended to make all iPhone models behave the same way (with or without bezel).

How to force view controller orientation in iOS 8?

For iOS 7 - 10:

Objective-C:

[[UIDevice currentDevice] setValue:@(UIInterfaceOrientationLandscapeLeft) forKey:@"orientation"];
[UINavigationController attemptRotationToDeviceOrientation];

Swift 3:

let value = UIInterfaceOrientation.landscapeLeft.rawValue
UIDevice.current.setValue(value, forKey: "orientation")
UINavigationController.attemptRotationToDeviceOrientation()

Just call it in - viewDidAppear: of the presented view controller.

iOS. How to enable and disable rotation on each UIViewController?

I have the answer.
On AppDelegate, if you rotate device, push viewcontroller, etc. This function always call

Update for swift 3/4

func application(_ application: UIApplication, supportedInterfaceOrientationsFor window: UIWindow?) -> UIInterfaceOrientationMask
{
    return self.restrictRotation
}

self.restrictRotation is a custom parameter.

How to use:

In Appdelegate:

 var restrictRotation:UIInterfaceOrientationMask = .portrait

In ViewController:

When method ViewDidLoad or viewWillAppear is called. We will change like this:

(UIApplication.shared.delegate as! AppDelegate).restrictRotation = .all 

and then this method on AppDelegate will be called.

func application(_ application: UIApplication, supportedInterfaceOrientationsFor window: UIWindow?) -> UIInterfaceOrientationMask
