Swift 3 | Unable to hide status bar on a ViewController

问题

I want to show the status bar on portrait mode only, when I rotate the screen the status bar hides as intended but if I push / show a new View Controller the status bar appears again.

I've tried the following without success:

• Setting View controller-based status bar appearance to NO in the info.plist file
• Using setNeedsStatusBarAppearanceUpdate() on self and on NavigationController
• Setting prefersStatusBarHidden: Bool to true
• Also tried UIApplication.shared.setStatusBarHidden(true, with: UIStatusBarAnimation.none)
• Also extending NavigationController. seen here

Any help will be appreciated. Thanks.

Try Following Code

override var prefersStatusBarHidden: Bool {

    if UIDevice.current.orientation.isPortrait{
        return false
    }
    return true
}
