Navigation bar and AVCaptureSession

I have a View controller with AVCaptureSession to scan barcode. I picked code here. I added navigation bar to it. But time, battery life, etc. didn't show.

I tried with UINavigation controller and NavigationBar widget.

Solution

  • You're most likely not showing the UIStatusBar, try adding this to your ViewController:

    override func prefersStatusBarHidden() -> Bool {
    return false
}

override func preferredStatusBarStyle() -> UIStatusBarStyle {
    return .Default
}

    Another option is setting values for status bar attributes in your main property list file:

    UIStatusBar attributes in .plist

    Status bar style defines the style of your status bar, see UIStatusBarStyle for what option you have.

    View controller-based status bar appearance defines whether you want to have different styles for each view controller or one style for all view controllers.
