Ios – navigation bar under status bar after video playback in landscape mode

1. Set the UIViewControllerBasedStatusBarAppearance to YES in the .plist file.

2. In the viewDidLoad do a [self setNeedsStatusBarAppearanceUpdate];

3. Add the following method:

   - (UIStatusBarStyle)preferredStatusBarStyle
   { 
       return UIStatusBarStyleLightContent; 
   }
   

Note: This does not work for controllers inside UINavigationController, please see Tyson's comment below :)

Swift 3 - This will work controllers inside UINavigationController. Add this code inside your controller.

// Preferred status bar style lightContent to use on dark background.
// Swift 3
override var preferredStatusBarStyle: UIStatusBarStyle {
    return .lightContent
}

Swift 5 and SwiftUI

For SwiftUI create a new swift file called HostingController.swift

import Foundation
import UIKit
import SwiftUI

class HostingController: UIHostingController<ContentView> {
    override var preferredStatusBarStyle: UIStatusBarStyle {
        return .lightContent
    }
}

Then change the following lines of code in the SceneDelegate.swift

window.rootViewController = UIHostingController(rootView: ContentView())

to

window.rootViewController = HostingController(rootView: ContentView())

I temporarily solved (through a hack) with the following code in the viewDidLoad of my controller. I have to specify that the code is specifically made for my case: since I explicitly disallow landscape orientation of my UINavigationController (see code above), the usual notification “UIDeviceOrientationDidChange” is not called when the playback finished and the window goes back to portrait. However, I hope there is a better option and this is a bug of the SDK, since it does not appear on iOS 7 and given the amount of auto-layout errors I get related to the video player (on which I have no control).

- (void)viewDidLoad
{
    [super viewDidLoad];

    // […]

     /* 
     Hack to fix navigation bar position/height on iOS 8 after closing fullscreen video

     Observe for “UIWindowDidRotateNotification” since “UIDeviceOrientationDidChangeNotification” is not called in the present conditions
     Check if the notification key (“UIWindowOldOrientationUserInfoKey”) in userInfo is either 3 or 4, which means the old orientation was landscape
     If so, correct the frame of the navigation bar to the proper size.

     */
    [[NSNotificationCenter defaultCenter] addObserverForName:@"UIWindowDidRotateNotification" object:nil queue:nil usingBlock:^(NSNotification *note) {
        if ([note.userInfo[@"UIWindowOldOrientationUserInfoKey"] intValue] >= 3) {
            self.navigationController.navigationBar.frame = (CGRect){0, 0, self.view.frame.size.width, 64};
        }
    }];
}

And then…

- (void)dealloc
{
    [[NSNotificationCenter defaultCenter] removeObserver:self forKeyPath:@"UIWindowDidRotateNotification"];
}
