Changing navigation bar color in Swift

I am using a Picker View to allow the user to choose the colour theme for the entire app.

I am planning on changing the colour of the navigation bar, background and possibly the tab bar (if that is possible).

I've been researching how to do this but can't find any Swift examples. Could anyone please give me an example of the code I would need to use to change the navigation bar colour and navigation bar text colour?

The Picker View is set up, I'm just looking for the code to change the UI colours.

If you're using iOS 13 to use this methods to change navigation bar color

Swift 4 and Swift 5 Compatible Xcode 15+

func navigationThemeSetting(navView: UIViewController) {
        
        if #available(iOS 15.0, *) {
            let navBarAppearance = UINavigationBarAppearance()
            navBarAppearance.configureWithOpaqueBackground()
            navBarAppearance.backgroundColor = .red
            navBarAppearance.titleTextAttributes = [NSAttributedString.Key.foregroundColor : .white]
            navView.navigationController?.navigationBar.standardAppearance = navBarAppearance;
            navView.navigationController?.navigationBar.scrollEdgeAppearance = navBarAppearance;
        } else {
            navView.navigationController?.navigationBar.barTintColor = ex_clrThemeColor
            navView.navigationController?.navigationBar.titleTextAttributes = [NSAttributedString.Key.foregroundColor : .white]
        }
    }

I'm working in Xcode 14.1 for iOS 16.1

I had to change the scrollEdgeAppearance to actually change the color of the navBar. The background color was only making a really translucent color even if I had disabled the translucent property.

So it went like this:

navigationController?.navigationBar.scrollEdgeAppearance = UIColor.*/your_color/*

None of the solutions worked for me so I'm sharing the one that did.

Swift 5, Xcode 13.4.1

Put the below inside the viewDidLoad():

let appearance = UINavigationBarAppearance()
        appearance.configureWithOpaqueBackground()
        appearance.backgroundColor = UIColor.systemBlue
        appearance.titleTextAttributes = [.foregroundColor: UIColor.white]
        navigationItem.standardAppearance = appearance
        navigationItem.scrollEdgeAppearance = appearance
        navigationItem.compactAppearance = appearance

This is the result

enter image description here

Remember to set all settings in the inspector to default. In case you need more adjustments search via Developers Documentation "Customizing Your App’s Navigation Bar"

Hope that helps.

In iOS 15, UIKit has extended the usage of the scrollEdgeAppearance, which by default produces a transparent background, to all navigation bars. Set scrollEdgeAppearance as below code.

if #available(iOS 15, *) {
        let appearance = UINavigationBarAppearance()
        appearance.configureWithOpaqueBackground()
        appearance.backgroundColor = < your tint color >
        navigationController?.navigationBar.standardAppearance = appearance;
        navigationController?.navigationBar.scrollEdgeAppearance = navigationController?.navigationBar.standardAppearance
    }

Below Codes are working for iOS 15

if #available(iOS 15, *) {
        // Navigation Bar background color
        let appearance = UINavigationBarAppearance()
        appearance.configureWithOpaqueBackground()
        appearance.backgroundColor = UIColor.yourColor
        
        // setup title font color
        let titleAttribute = [NSAttributedString.Key.font: UIFont.systemFont(ofSize: 25, weight: .bold), NSAttributedString.Key.foregroundColor: UIColor.yourColor]
        appearance.titleTextAttributes = titleAttribute
        
        navigationController?.navigationBar.standardAppearance = appearance
        navigationController?.navigationBar.scrollEdgeAppearance = appearance
    }

Here are some very basic appearance customization that you can apply app wide:

UINavigationBar.appearance().backgroundColor = UIColor.greenColor()
UIBarButtonItem.appearance().tintColor = UIColor.magentaColor()
//Since iOS 7.0 UITextAttributeTextColor was replaced by NSForegroundColorAttributeName
UINavigationBar.appearance().titleTextAttributes = [UITextAttributeTextColor: UIColor.blueColor()]
UITabBar.appearance().backgroundColor = UIColor.yellowColor();

Swift 5.4.2:

UINavigationBar.appearance().backgroundColor = .green // backgorund color with gradient
// or
UINavigationBar.appearance().barTintColor = .green  // solid color
    
UIBarButtonItem.appearance().tintColor = .magenta
UINavigationBar.appearance().titleTextAttributes = [NSAttributedString.Key.foregroundColor : UIColor.blue]
UITabBar.appearance().barTintColor = .yellow

Swift 5, an easy approach with UINavigationController extension. At the bottom of this answer are extensions and previews.

First view controller (Home):

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)

    navigationController?.setTintColor(.white)
    navigationController?.backgroundColor(.orange)
}

Second view controller (Details):

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
    navigationController?.transparentNavigationBar()
    navigationController?.setTintColor(.black)
}

Extensions for UINavigationController:

extension UINavigationController {
    func transparentNavigationBar() {
        self.navigationBar.setBackgroundImage(UIImage(), for: .default)
        self.navigationBar.shadowImage = UIImage()
        self.navigationBar.isTranslucent = true
    }

    func setTintColor(_ color: UIColor) {
        self.navigationBar.titleTextAttributes = [NSAttributedString.Key.foregroundColor: color]
        self.navigationBar.tintColor = color
    }

    func backgroundColor(_ color: UIColor) {
        navigationBar.setBackgroundImage(nil, for: .default)
        navigationBar.barTintColor = color
        navigationBar.shadowImage = UIImage()
    }
}

simply call the this extension and pass the color it will automatically change the color of nav bar

extension UINavigationController {
    
     func setNavigationBarColor(color : UIColor){
            self.navigationBar.barTintColor = color
        }
    }

in the view didload or in viewwill appear call

self.navigationController?.setNavigationBarColor(color: <#T##UIColor#>)

If you're using iOS 13 or 14 and large title, and want to change navigation bar color, use following code:

Refer to barTintColor not applied when NavigationBar is Large Titles

    fileprivate func setNavigtionBarItems() {
        if #available(iOS 13.0, *) {
            let appearance = UINavigationBarAppearance()
            appearance.configureWithDefaultBackground()
            appearance.backgroundColor = .brown
//            let naviFont = UIFont(name: "Chalkduster", size: 30) ?? .systemFont(ofSize: 30)
//            appearance.titleTextAttributes = [NSAttributedString.Key.font: naviFont]
            
            navigationController?.navigationBar.prefersLargeTitles = true
            navigationController?.navigationBar.standardAppearance = appearance
            navigationController?.navigationBar.scrollEdgeAppearance = appearance
            //navigationController?.navigationBar.compactAppearance = appearance
        } else {
            // Fallback on earlier versions
            navigationController?.navigationBar.barTintColor = .brown
        }
    }

This took me 1 hour to figure out what is wrong in my code:(, since I'm using large title, it is hard to change the tintColor with largeTitle, why apple makes it so complicated, so many lines to just make a tintColor of navigationBar.

My two cents:

a) setting navigationBar.barTintColor / titleTextAttributes do work in any view (pushed, added..and so on in init..

b) setting appearence does not work everywhere:

  • You can call it on AppDelegate
  • " " 1st level view
  • if You call it again in subsequent pushed views, does MNOT work

SwiftUI note:

a) does not apply (no navigationBar, unless you pass via UIViewControllerRepresentable trick..) b) is valid for SwiftUI: same behaviour.

This version also removes the 1px shadow line under the navigation bar:

Swift 5: Put this in your AppDelegate didFinishLaunchingWithOptions

UINavigationBar.appearance().barTintColor = UIColor.black
UINavigationBar.appearance().tintColor = UIColor.white
UINavigationBar.appearance().titleTextAttributes = [NSAttributedString.Key.foregroundColor: UIColor.white]
UINavigationBar.appearance().isTranslucent = false
UINavigationBar.appearance().setBackgroundImage(UIImage(), for: .any, barMetrics: .default)
UINavigationBar.appearance().shadowImage = UIImage()

I'm writing this for those that still have problems with the solutions here.

I'm using Xcode Version 11.4 (11E146). The one working for me is:

navigationController?.navigationBar.barTintColor = UIColor.white
navigationController?.navigationBar.tintColor = UIColor.black

BUT!, if you set the barTintColor in storyboard to any other value than "default" this 2 lines of code will have no effect.

So, be carefull and set back to default barTintColor in Storyboard. Oh Apple...

UINavigationBar.appearance().barTintColor = UIColor(red: 46.0/255.0, green: 14.0/255.0, blue: 74.0/255.0, alpha: 1.0)
UINavigationBar.appearance().tintColor = UIColor.whiteColor()
UINavigationBar.appearance().titleTextAttributes = [NSForegroundColorAttributeName : UIColor.whiteColor()]

Just paste this line in didFinishLaunchingWithOptions in your code.

The appearance() function not always work for me. So I prefer to create a NC object and change its attributes.

var navBarColor = navigationController!.navigationBar
navBarColor.barTintColor =
    UIColor(red:  255/255.0, green: 0/255.0, blue: 0/255.0, alpha: 100.0/100.0)
navBarColor.titleTextAttributes =
    [NSForegroundColorAttributeName: UIColor.whiteColor()]

Also if you want to add an image instead of just text, that works as well

var imageView = UIImageView(frame: CGRect(x: 0, y: 0, width: 70, height: 70))
imageView.contentMode = .ScaleAspectFit

var image = UIImage(named: "logo")
imageView.image = image
navigationItem.titleView = imageView

SWIFT 4 - Smooth transition (best solution):

If you're moving back from a navigation controller and you have to set a diffrent color on the navigation controller you pushed from you want to use

override func willMove(toParentViewController parent: UIViewController?) {
    navigationController?.navigationBar.barTintColor = .white
    navigationController?.navigationBar.tintColor = Constants.AppColor
}

instead of putting it in the viewWillAppear so the transition is cleaner.

SWIFT 4.2

override func willMove(toParent parent: UIViewController?) {
    navigationController?.navigationBar.barTintColor = UIColor.black
    navigationController?.navigationBar.tintColor = UIColor.black
}

Make sure to set the Button State for .normal

extension UINavigationBar {

    func makeContent(color: UIColor) {
        let attributes: [NSAttributedString.Key: Any]? = [.foregroundColor: color]

        self.titleTextAttributes = attributes
        self.topItem?.leftBarButtonItem?.setTitleTextAttributes(attributes, for: .normal)
        self.topItem?.rightBarButtonItem?.setTitleTextAttributes(attributes, for: .normal)
    }
}

Navigation Bar:

navigationController?.navigationBar.barTintColor = UIColor.green

Replace greenColor with whatever UIColor you want, you can use an RGB too if you prefer.

Navigation Bar Text:

navigationController?.navigationBar.titleTextAttributes = [.foregroundColor: UIColor.orange]

Replace orangeColor with whatever color you like.

Tab Bar:

tabBarController?.tabBar.barTintColor = UIColor.brown

Tab Bar Text:

tabBarController?.tabBar.tintColor = UIColor.yellow

On the last two, replace brownColor and yellowColor with the color of your choice.

To do this on storyboard (Interface Builder Inspector)

With help of IBDesignable, we can add more options to Interface Builder Inspector for UINavigationController and tweak them on storyboard. First, add the following code to your project.

@IBDesignable extension UINavigationController {
    @IBInspectable var barTintColor: UIColor? {
        set {
            guard let uiColor = newValue else { return }
            navigationBar.barTintColor = uiColor
        }
        get {
            guard let color = navigationBar.barTintColor else { return nil }
            return color
        }
    }
}

Then simply set the attributes for navigation controller on storyboard.

enter image description here

This approach may also be used to manage the color of the navigation bar text from the storyboard:

@IBInspectable var barTextColor: UIColor? {
  set {
    guard let uiColor = newValue else {return}
    navigationBar.titleTextAttributes = [NSAttributedStringKey.foregroundColor: uiColor]
  }
  get {
    guard let textAttributes = navigationBar.titleTextAttributes else { return nil }
    return textAttributes[NSAttributedStringKey.foregroundColor] as? UIColor
  }
}

In Swift 4

You can change the color of navigation bar. Just use this below code snippet in viewDidLoad()

Navigation Bar color

self.navigationController?.navigationBar.barTintColor = UIColor.white

Navigation Bar Text Color

self.navigationController?.navigationBar.titleTextAttributes = [NSAttributedStringKey.foregroundColor: UIColor.purple]

For iOS 11 Large Title Navigation Bar, you need to use largeTitleTextAttributes property

self.navigationController?.navigationBar.largeTitleTextAttributes = [NSAttributedStringKey.foregroundColor: UIColor.purple]

A Better Solution for this to make a Class for common Navigation bars

I have 5 Controllers and each controller title is changed to orange color. As each controller has 5 navigation controllers so i had to change every one color either from inspector or from code.

So i made a class instead of changing every one Navigation bar from code i just assign this class and it worked on all 5 controller Code reuse Ability. You just have to assign this class to Each controller and thats it.

import UIKit

   class NabigationBar: UINavigationBar {
      required init?(coder aDecoder: NSCoder) {
       super.init(coder: aDecoder)
    commonFeatures()
 }

   func commonFeatures() {

    self.backgroundColor = UIColor.white;
      UINavigationBar.appearance().titleTextAttributes =     [NSAttributedStringKey.foregroundColor:ColorConstants.orangeTextColor]

 }

Simple one liner that you can use in ViewDidLoad()

//Change Color
    self.navigationController?.navigationBar.barTintColor = UIColor.red
//Change Text Color
    self.navigationController?.navigationBar.titleTextAttributes = [NSForegroundColorAttributeName: UIColor.white]

If you have customized navigation controller, you can use above code snippet. So in my case, I've used as following code pieces.

Swift 3.0, XCode 8.1 version

navigationController.navigationBar.barTintColor = UIColor.green

Navigation Bar Text:

navigationController.navigationBar.titleTextAttributes = [NSForegroundColorAttributeName: UIColor.orange]

It is very helpful talks.

If you don't mind to use swift frameworks then us UINeraida to change navigation background as UIColor or HexColor or UIImage and change navigation back button text programmatically, change complete forground text color.

For UINavigationBar

    neraida.navigation.background.color.hexColor("54ad00", isTranslucent: false, viewController: self)
    
    //Change navigation title, backbutton colour
    
    neraida.navigation.foreground.color.uiColor(UIColor.white, viewController: self)
    
    //Change navigation back button title programmatically
    
    neraida.navigation.foreground.backButtonTitle("Custom Title", ViewController: self)
    
    //Apply Background Image to the UINavigationBar
    
    neraida.navigation.background.image("background", edge: (0,0,0,0), barMetrics: .default, isTranslucent: false, viewController: self)
