Why is the UINavigationBar turning black? - Drtun9 - 07-19-2023
**Problem:**
I have a `UITableViewController` embedded in a `UINavigationController`. Pressing a cell in the table view switches to another table view controller. In said table view controller, I'd like for the navigation bar to be invisible while still keeping the tab bar items so I added the following to its `viewDidLoad()`:
self.navigationController?.navigationBar.setBackgroundImage(UIImage(), forBarMetrics: .default)
self.navigationController?.navigationBar.shadowImage = UIImage()
self.navigationController?.navigationBar.isTranslucent = true
self.navigationController?.navigationBar.tintColor = .black
For the first UITableViewController, I'd like the navigation bar to be normal so in its `viewDidAppear()` I did the following:
self.navigationController?.navigationBar.isTranslucent = false
Everything is working fine except during the transition (which I am doing via `performSegueWithIdentifier`) the navigation bar on the first view controller disappears into blackness which looks ugly to be honest. Is there any way to prevent/fix this?

Below code works for me,
if (@available(iOS 13.0, *)) {
UINavigationBarAppearance *appearance = [UINavigationBarAppearance new];
[appearance configureWithOpaqueBackground];
[appearance setBackgroundColor:UIColor.yellowColor];
appearance.titleTextAttributes = @{NSForegroundColorAttributeName: UIColor.whiteColor};
controller.navigationItem.standardAppearance = appearance;
controller.navigationItem.scrollEdgeAppearance = appearance;
controller.navigationItem.compactAppearance = appearance;
}

iOS 15 changed the way nav bars rendered. They are transparent by default. In most cases by default, no content is beneath the nav bars resulting in black color. The following code in AppDelegate(didFinishLaunchingWithOptions) fixed that for me.
if #available(iOS 15.0, *) {
let navBarAppearance = UINavigationBarAppearance()
navBarAppearance.configureWithOpaqueBackground()
//Configure additional customizations here
UINavigationBar.appearance().standardAppearance = navBarAppearance
UINavigationBar.appearance().scrollEdgeAppearance = navBarAppearance
}

Below code helped me to get rid of **black navigationBar** in **iOS 15+**
if #available(iOS 15, *) {
let textAttributes = [NSAttributedString.Key.foregroundColor: UIColor.black]
let appearance = UINavigationBarAppearance()
appearance.configureWithOpaqueBackground()
appearance.titleTextAttributes = textAttributes
appearance.backgroundColor = UIColor.white // UIColor(red: 0.0/255.0, green: 125/255.0, blue: 0.0/255.0, alpha: 1.0)
appearance.shadowColor = .clear //removing navigationbar 1 px bottom border.
UINavigationBar.appearance().standardAppearance = appearance
UINavigationBar.appearance().scrollEdgeAppearance = appearance
}

for me otherwise helped (**Swift 5**):
self.navigationController?.navigationBar.isTranslucent = false
self.navigationController?.navigationBar.barTintColor = UIColor.green //change to needed color

On viewDidLoad add:
extendedLayoutIncludesOpaqueBars = true

Just change your navigationController view's backgroundColor
navigationController?.view.backgroundColor = // whatever

Change the window background color for you application to a color that suits you:
self.window?.backgroundColor = .white
**Other solutions causes other problems in multiple inner screens.**

I ran into this again recently, and discovered a way to fix it in the storyboard. If you're using opaque navigation bars, ensure the "Extend Edges" setting for "Under Opaque Bars" is set. In fact, I just set all three of them as shown below:-

I had a very similar problem recently. Try setting `self.navigationController?.navigationBar.translucent = true` in both view controllers and `self.edgesForExtendedLayout = UIRectEdgeNone`. <br>
Storyboard version: [Extended Edges - Under Top Bars][1]
