When I override overrideUserInterfaceStyle to light and dark mode is set to on, on the device, it is not changing the status bar style to .lightcontent.
overrideUserInterfaceStyle = .light
self.navigationController?.navigationBar.largeTitleTextAttributes = [.foregroundColor: UIColor.black]
self.navigationController?.navigationBar.titleTextAttributes = [.foregroundColor: UIColor.black]
self.navigationController?.navigationBar.barStyle = .default
self.setNeedsStatusBarAppearanceUpdate()
That is my code for overridng the interfacce style. When I do this the statusbar is staying with dark content.
If your content is inside a UINavigationController, you won't get what you expect. You will have to subclass UINavigationController to reach into its content and promote that view controller's overridden value.
See this thread for some answers: preferredStatusBarStyle isn't called

I have a problem when I try to change interface style (dark or light). If I set dark mode I get the navigation bar remains light when I scroll. If I set light mode the navigation bar becomes black. How can I solve this?
I use this code to change userInterfaceStyle:
window?.overrideUserInterfaceStyle = .dark
I found a solution by myself.
For everyone that has this problem the solution is:
let appearance = UINavigationBarAppearance()
appearance.configureWithOpaqueBackground()
appearance.backgroundColor = .systemBackground
UINavigationBar.appearance().standardAppearance = appearance
UINavigationBar.appearance().scrollEdgeAppearance = UINavigationBar.appearance().standardAppearance
put this code inside TabBarController
Recently I updated my Xcode to 13 and after that, I am facing some issues with the navigation bar and Status bar. I am using the tab bar in my view controller. After updating the Xcode, according to the version, I added some code related to the navigation bar.
if #available(iOS 15.0, *) {
tableView.sectionHeaderTopPadding = 0
let appearance = UINavigationBarAppearance()
appearance.configureWithOpaqueBackground()
appearance.backgroundColor = UIColor(red: 58/255,green: 24/255, blue: 93/255, alpha: 1.0)
appearance.titleTextAttributes = [NSAttributedString.Key.foregroundColor:UIColor.white]
// Customizing our navigation bar
navigationController?.navigationBar.tintColor = .white
navigationController?.navigationBar.barTintColor = .white
navigationController?.navigationBar.standardAppearance = appearance
navigationController?.navigationBar.scrollEdgeAppearance = appearance
}
Everything is working when I first opened the app. When I click on the other tab and then this tab. The status bar text color is changing.
I tried different ways to set the status bar text color. But nothing worked for me.
Use this function:
extension YourViewController {
override var preferredStatusBarStyle: UIStatusBarStyle {
.lightContent
}
}
If you just want to set to white colour you status bar in the entire project you can easily do it by adding the following keys into your project.plist file:
<key>UIViewControllerBasedStatusBarAppearance</key>
<false/>
<key>UIStatusBarStyle</key>
<string>UIStatusBarStyleLightContent</string>
<key>UIUserInterfaceStyle</key>
<string>Light</string>
So, what does these keys do... You are just defining that you status bar colour will not be controlled by the any view controller and that the default colour will be "light theme" that is pretty much the white colour that you want in this case...
this would be the best approach if you do not intent to update the status bar colour all over the place.
this was tested and is working as expected on Xcode 13 and iOS [13.x,14.x,15.x]
If you want to update to customise or update the colours for the navigation bar you would should be able to do with an extension like this one bellow, just few examples but you guys should get what I mean:
extension UINavigationBar {
func clearBackground() {
let navBarAppearance = UINavigationBarAppearance()
navBarAppearance.configureWithTransparentBackground()
navBarAppearance.shadowColor = UIColor.clear
navBarAppearance.titleTextAttributes = [NSAttributedString.Key.foregroundColor: UIColor.white]
self.standardAppearance = navBarAppearance
self.scrollEdgeAppearance = navBarAppearance
}
func blackColor() {
// Create an Appearance and customise as you wish.
// in this case just a black background with titles in white.
let navBarAppearance = UINavigationBarAppearance()
navBarAppearance.configureWithOpaqueBackground()
navBarAppearance.shadowColor = UIColor.black
navBarAppearance.titleTextAttributes = [NSAttributedString.Key.foregroundColor: UIColor.white]
self.standardAppearance = navBarAppearance
self.scrollEdgeAppearance = navBarAppearance
}
}
with this code you should be able to easy update on any view controller by just calling something like:
override func viewDidLoad() {
super.viewDidLoad()
// set the navigation bar color as transparent
self.navigationController?.navigationBar.clearBackground()
}
I'm applying the new appearance API for NavigationBar and I'm struggling with the status bar content (text). On Info.plist I forced to use the light mode because most of the app is white, but in one of my viewControllers, the navigation bar is dark blue (almost black) so the content within this bar needs to be white.
I used to use navigationBar.barStyle = .black on versions up to iOS 12.4, but for iOS 13 and above it doesn't work anymore. Follow the code I've tried and failed.
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
if let navController = self.navigationController {
let navBarAppearance = navController.navigationBar.standardAppearance.copy()
navBarAppearance.configureWithOpaqueBackground()
navBarAppearance.shadowImage = UIImage()
navBarAppearance.backgroundColor = LayoutBootstrap.colors.primary.solid // Dark blue
navController.navigationBar.standardAppearance = navBarAppearance
navController.navigationBar.barStyle = .black
}
}
Status bar content is black
PS: On didFinishLaunchingWithOptions I already called a default configuration appearance for NavigationBar and Items
Do you guys have any suggestion?
Thanks in advance.
You need to set the status bar style as well
UIApplication.shared.statusBarStyle = .lightContent
I have some problems with my tabbed view when I set isTranslucent to false in combination with a NavigationView.
Does anyone know how to fix this? The problem is shown in the attached image.
I need translucent set to false otherwise I can't get the dark color.
You can set backgroundColor. Don't set isTranslucent to false or it will create these artefacts you mentioned.
UITabBar.appearance().backgroundColor = .black
UINavigationBar.appearance().backgroundColor = .black
It becomes much darker. It isn't completely opaque though.
Edit: Just watched Modernizing Your UI for iOS 13 This is the way to do it :
The TabView and NavigationView are actually UIHostedController for the legacy UITabBarController and UINavigationController:
let appearance = UITabBarAppearance()
appearance.configureWithOpaqueBackground()
appearance.titleTextAttributes = [.foregroundColor: UIColor.white]
appearance.largeTitleTextAttributes = [.foregroundColor: UIColor .white]
Then set the appearance on the various type of appearance.
tabBar.standardAppearance = appearance
2nd Edit:
extension UINavigationController {
override open func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
let appearance = UINavigationBarAppearance()
appearance.configureWithOpaqueBackground()
navigationBar.standardAppearance = appearance
navigationBar.compactAppearance = appearance
navigationBar.scrollEdgeAppearance = appearance
}
}
extension UITabBarController {
override open func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
let appearance = UITabBarAppearance()
appearance.configureWithOpaqueBackground()
tabBar.standardAppearance = appearance
}
}
There should be a cleaner way to get to both tabBar and navBar.

I was using UIKit with SwiftUI. My Tab bar was creating in storyboard but the view for which I was getting extra bottom space was a swiftui view as you mentioned. I tried all above solution but Nothing worked for me.
I am using Xcode 12.4 for development. My solution is to mark Translucent to true in storyboard and Bottom extra gray bar was gone.
Just customize it in an extension like this:
extension UITabBarController {
override open func viewDidLoad() {
super.viewDidLoad()
let appearance = UITabBarAppearance()
appearance.backgroundColor = .black
tabBar.standardAppearance = appearance
}
}
Pay attention that the overridden function must be viewDidLoad(). At least it doesn't work for me when it is a viewDidAppear(:) function.
It's easier than all that, just delete the next line:
UITabBar.appearance().isTranslucent = false
I have a UITabBar and I want to make it blurred. I wrote the following code:
import UIKit
class TabBarController:UITabBarController {
override func viewDidLoad() {
super.viewDidLoad()
let blur = UIBlurEffect(style: UIBlurEffectStyle.Light)
let blurView = UIVisualEffectView(effect: blur)
blurView.frame = self.view.bounds
blurView.autoresizingMask = [.FlexibleWidth, .FlexibleHeight]
self.view.layer.insertSublayer(blurView, atIndex: 0)
}
}
but somehow the last line throws error:
Cannot convert value of type 'UIVisualEffectView' to expected argument
type 'CALayer'
how can I fix that?
I changed the last line to:
self.tabBar.addSubview(blurView)
but now the whole tabbar is blurred (even with icons and they are not visible). When I changed this line to:
self.tabBar.sendSubviewToBack(blurView)
then the tabbar is visible, but not blurred. I want to achieve effect from accepted answer from here Black background on transparent UITabBar but here it is uitabbar and I'm using uitabbarcontroller... Can you help me with applying blur in my case?
You just add the blur view as a subview:
self.view.addSubview(blurView)
Since you just want to blue the tab bar and this class is a tab bar controller, you can do:
self.tabBar.addSubview(blueView)
You also need to change the frame:
blurView.frame = self.tabBar.bounds
why don't you just use the barTintColor property on your TabBarController?
self.tabBar.translucent = true
self.tabBar.barTintColor = UIColor.blackColor()
You don't even need to subclass UITabBarController. You can call this on any UIViewController.
self.tabBarController?.tabBar.translucent = true
self.tabBarController?.tabBar.barTintColor = UIColor.blackColor()
If I understood correctly from the following comment that you posted, you want to change the UITabBar to be black in colour but still blurred.
And yes, I noticed that the UITabBarController is blurred by default, but I would like to make it blurred with specific style (.Dark).
Doing this since iOS 7 has actually become quite easy. Simply change the barStyle of your UITabBar to .black. Put the following code in your UIViewController's viewDidLoad method (note that UITabBar is translucent by default, so you don't need to specify that again).
tabBarController?.tabBar.barStyle = .black
If you want to set it back to the regular, white barStyle, change it back to .default.
tabBarController?.tabBar.barStyle = .default
You may even do this from within Interface Builder by selecting the Tab Bar in your UITabBarController's hierarchy and changing its Style to Black.
I have a solution, all you need is configure your UITabBar as following:
// next code will make tabBar fully transparent
tabBar.isTranslucent = true
tabBar.backgroundImage = UIImage()
tabBar.shadowImage = UIImage() // add this if you want remove tabBar separator
tabBar.barTintColor = .clear
tabBar.backgroundColor = .black // here is your tabBar color
tabBar.layer.backgroundColor = UIColor.clear.cgColor
If you want to add blur, do this:
let blurEffect = UIBlurEffect(style: .dark) // here you can change blur style
let blurView = UIVisualEffectView(effect: blurEffect)
blurView.frame = tabBar.bounds
blurView.autoresizingMask = .flexibleWidth
tabBar.insertSubview(blurView, at: 0)
As a result:
Attach bottom constraint to the bottom of the view instead of Safe Area
It just might not be a problem with your TabBar but with tableView constraints.
Tab bar is blurred by default.
