The background text in the status bar is still black. How do I change the color to white?
// io8, swift, Xcode 6.0.1
override func viewDidLoad() {
super.viewDidLoad()
self.navigationController?.navigationBar.barTintColor = UIColor.blackColor()
self.navigationController?.navigationBar.titleTextAttributes = [NSForegroundColorAttributeName: UIColor.orangeColor()]
}
回答1:
In AppDelegate.swift
, in application(_:didFinishLaunchingWithOptions:)
I put the following:
UINavigationBar.appearance().barTintColor = UIColor(red: 234.0/255.0, green: 46.0/255.0, blue: 73.0/255.0, alpha: 1.0)
UINavigationBar.appearance().tintColor = UIColor.white
UINavigationBar.appearance().titleTextAttributes = [NSAttributedStringKey.foregroundColor : UIColor.white]
For titleTextAttributes
, the docs say:
You can specify the font, text color, text shadow color, and text
shadow offset for the title in the text attributes dictionary

I like Alex's answer. If you want something quick to try out in a ViewController
make sure you use
viewWillAppear()
override func viewWillAppear(animated: Bool) {
super.viewWillAppear(animated)
var nav = self.navigationController?.navigationBar
nav?.barStyle = UIBarStyle.Black
nav?.tintColor = UIColor.white
nav?.titleTextAttributes = [NSForegroundColorAttributeName: UIColor.orange]
//nav?.titleTextAttributes = [NSAttributedString.Key.foregroundColor: UIColor.orange] // swift 4.2
}

To change the color universally, this code should sit in the NavigationController
's viewDidLoad
function:
class NavigationController: UINavigationController, UIViewControllerTransitioningDelegate {
override func viewDidLoad() {
super.viewDidLoad()
// Status bar white font
self.navigationBar.barStyle = UIBarStyle.Black
self.navigationBar.tintColor = UIColor.whiteColor()
}
}
To change it per ViewController
you would have to reference the NavigationController
from the ViewController
and write similar lines in that ViewController
's viewWillAppear
function.

//In Swift 4
self.navigationController?.navigationBar.titleTextAttributes = [NSAttributedStringKey.foregroundColor: UIColor.white]

To work in objective-c I have to put the following lines in viewWillAppear
in my CustomViewController.
[self.navigationController.navigationBar setBarTintColor:[UIColor whiteColor]];
[self.navigationController.navigationBar setTranslucent:NO];
For Swift2.x this works:
self.navigationController?.navigationBar.barTintColor = UIColor.redColor()
For Swift3.x this works:
self.navigationController?.navigationBar.barTintColor = UIColor.red

To do this job in 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 {
navigationBar.barTintColor = newValue
}
get {
guard let color = navigationBar.barTintColor else { return nil }
return color
}
}
@IBInspectable var tintColor: UIColor? {
set {
navigationBar.tintColor = newValue
}
get {
guard let color = navigationBar.tintColor else { return nil }
return color
}
}
@IBInspectable var titleColor: UIColor? {
set {
guard let color = newValue else { return }
navigationBar.titleTextAttributes = [NSForegroundColorAttributeName: color]
}
get {
return navigationBar.titleTextAttributes?["NSForegroundColorAttributeName"] as? UIColor
}
}
}
Then simply set the attributes for UINavigationController on storyboard.

If you want to set the tint color and bar color for the entire app, the following code can be added to AppDelegate.swift in
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
var navigationBarAppearace = UINavigationBar.appearance()
navigationBarAppearace.tintColor = UIColor(red:1.00, green:1.00, blue:1.00, alpha:1.0)
navigationBarAppearace.barTintColor = UIColor(red:0.76, green:0.40, blue:0.40, alpha:1.0)
navigationBarAppearace.titleTextAttributes = [NSForegroundColorAttributeName: UIColor.white]
return true
`
Navigation barTintColor and tintColor is set

For custom color to TitleText
at NavigationBar
, here a simple and short code for Swift 3:
UINavigationBar.appearance().titleTextAttributes = [NSForegroundColorAttributeName : UIColor.white]
or
navigationController?.navigationBar.titleTextAttributes = [NSForegroundColorAttributeName :UIColor.white]
回答13:

Swift 4.2 version of Albert's answer-
UINavigationBar.appearance().barTintColor = UIColor(red: 234.0/255.0, green: 46.0/255.0, blue: 73.0/255.0, alpha: 1.0)
UINavigationBar.appearance().tintColor = UIColor.white
UINavigationBar.appearance().titleTextAttributes = [.foregroundColor : UIColor.white]
