Change the color of iOS Navigation Bar

Question

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.n         


        

Answer 1

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

1. the segue should be different than "show"

2. 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()]
   }
