Change the color of iOS Navigation Bar
IosSwiftUinavigationcontrollerIos Problem Overview
I'm trying to change the color of my navigator bar but I found that it's only impossible if the navigator is the root one.
I'm trying this:
self.navigationController?.navigationBar.translucent = true
self.navigationController!.navigationBar.barTintColor = UIColor.blueColor()
All my Viewcontrollers
are related to navigator controllers. However nothing is changed. In fact I tried to make the same things from storyboard but it works only if I'm in the first navigator.
I tried to read everything related to this problem but found nothing
I could add any item to the navigator bar like this
let HomeImage = UIImage(named: "home")!
let Home : UIBarButtonItem = UIBarButtonItem(image: HomeImage, style: .Plain, target: self, action: "home:")
navigationItem.rightBarButtonItem = Home

In fact, i found that the solution was to use in the AppDelegate.siwft
:
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Override point for customization after application launch.
UINavigationBar.appearance().barTintColor = UIColor(red: 0, green: 0/255, blue: 205/255, alpha: 1)
UINavigationBar.appearance().tintColor = UIColor.whiteColor()
UINavigationBar.appearance().titleTextAttributes = [NSForegroundColorAttributeName:UIColor.whiteColor()]
return true
}
and then in each view controller, that we need another background color or something else
-
the segue should be different than "show"
-
use the func
viewWillAppear
override func viewWillAppear(animated: Bool) { super.viewWillAppear(animated) self.navigationController?.navigationBar.barTintColor = UIColor.whiteColor() self.navigationController?.navigationBar.tintColor = UIColor.blueColor() self.navigationController!.navigationBar.titleTextAttributes = [NSForegroundColorAttributeName: UIColor.blueColor()] }

Updated for Swift 3
UINavigationBar.appearance().barTintColor = .black
UINavigationBar.appearance().tintColor = .white
UINavigationBar.appearance().titleTextAttributes = [NSForegroundColorAttributeName: UIColor.white]
UINavigationBar.appearance().isTranslucent = false
Swift 4
UINavigationBar.appearance().barTintColor = .black
UINavigationBar.appearance().tintColor = .white
UINavigationBar.appearance().titleTextAttributes = [NSAttributedStringKey.foregroundColor: UIColor.white]
UINavigationBar.appearance().isTranslucent = false
Swift 5
UINavigationBar.appearance().barTintColor = .black
UINavigationBar.appearance().tintColor = .white
UINavigationBar.appearance().titleTextAttributes = [NSAttributedString.Key.foregroundColor: UIColor.white]
UINavigationBar.appearance().isTranslucent = false
Solution 3 - Ios
Swift 4.2:
//To change Navigation Bar Background Color
UINavigationBar.appearance().barTintColor = UIColor.blue
//To change Back button title & icon color
UINavigationBar.appearance().tintColor = UIColor.white
//To change Navigation Bar Title Color
UINavigationBar.appearance().titleTextAttributes = [NSAttributedString.Key.foregroundColor: UIColor.white]
Swift 3.x:
//To change Navigation Bar Background Color
UINavigationBar.appearance().barTintColor = UIColor.blue
//To change Back button title & icon color
UINavigationBar.appearance().tintColor = UIColor.white
//To change Navigation Bar Title Color
UINavigationBar.appearance().titleTextAttributes = [NSForegroundColorAttributeName: UIColor.white]
Solution 4 - Ios
For changing the navigation bar theme color throughout the full app you can do this by using UiNavigation bar appearance.
UINavigationBar.appearance().barTintColor = UIColor.redColor()
Solution 5 - Ios
If your view controller is embedded in navigation controller then you can remove this default navigation bar and can use a custom navigation bar for that view controller.
Then you can do look like
UINavigationBar.appearance().barTintColor = UIColor(red: 46.0/255.0, green: 14.0/255.0, blue: 74.0/255.0, alpha: 1.0)
Solution 6 - Ios
Make the following update to the AppDelegate.Swift file i.e.
UINavigationBar.appearance().barTintColor = UIColor(red:x.xx, green:x.xx, blue:x.xx, alpha:1.0)
Refer to example below
import UIKit
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
UINavigationBar.appearance().barTintColor = UIColor(red:0.03, green:0.25, blue:0.11, alpha:1.0)
UINavigationBar.appearance().tintColor = UIColor.white
UINavigationBar.appearance().titleTextAttributes = [NSForegroundColorAttributeName:UIColor.white]
return true
}
func applicationWillResignActive(_ application: UIApplication) {
// Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.
// Use this method to pause ongoing tasks, disable timers, and invalidate graphics rendering callbacks. Games should use this method to pause the game.
}
func applicationDidEnterBackground(_ application: UIApplication) {
// Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later.
// If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.
}
func applicationWillEnterForeground(_ application: UIApplication) {
// Called as part of the transition from the background to the active state; here you can undo many of the changes made on entering the background.
}
func applicationDidBecomeActive(_ application: UIApplication) {
// Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.
}
func applicationWillTerminate(_ application: UIApplication) {
// Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.
}
}
Solution 7 - Ios
self.navigationController?.navigationBar.barTintColor = UIColor.gray
Solution 8 - Ios
For black nav bar try this:
navigationController?.navigationBar.barStyle = .black
Solution 9 - Ios
self.navigationController.navigationBar.barTintColor = [UIColor blackColor];
Solution 10 - Ios
solving this issue for SwiftUI:
init() {
// For .navigationBarTitle(Text("Update"), displayMode: .automatic)
let coloredAppearance = UINavigationBarAppearance()
coloredAppearance.backgroundColor = .black
coloredAppearance.largeTitleTextAttributes = [.foregroundColor: UIColor.white]
// to make everything work normally
UINavigationBar.appearance().standardAppearance = coloredAppearance
UINavigationBar.appearance().scrollEdgeAppearance = coloredAppearance
// For .navigationBarTitle(Text("Update"), displayMode: .inline)
// UINavigationBar.appearance().barTintColor = .black
// UINavigationBar.appearance().titleTextAttributes = [.foregroundColor: UIColor.white]
}
var body: some View {
NavigationView {
// Text("Screen")
let HomeImage = UIImage(named: "home")!
let Home : UIBarButtonItem = UIBarButtonItem(image: HomeImage, style: .Plain, target: self, action: "home:")
navigationItem.rightBarButtonItem = Home
.navigationBarTitle(Text("Update"), displayMode: .automatic)
}
// that means only show one view at a time no matter what device I'm working
.navigationViewStyle(StackNavigationViewStyle())
}
