Set rootViewController of UINavigationController by method other than initWithRootViewController

How Do I set the rootViewController of UINavigationController by a method other than initWithRootViewController?

I want use initWithNavigationBarClass:toolbarClass: to deliver a custom toolbar for my NavigationController, so I don't think I can use initWithRootViewController.

Knowledge Sharing Using Swift:

Changing root view controller from class other than app delegate.swift

let appdelegate = UIApplication.sharedApplication().delegate as! AppDelegate
let mainStoryboard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
var homeViewController = mainStoryboard.instantiateViewControllerWithIdentifier("HomeViewController") as! HomeViewController
let nav = UINavigationController(rootViewController: homeViewController)
appdelegate.window!.rootViewController = nav

Hope this will helpful for someone.

Changing rootviewcontroller With Animation can be achieved with:

UIView.transitionWithView(self.window!, duration: 0.5, options: UIViewAnimationOptions.TransitionFlipFromLeft, animations: {
    self.window?.rootViewController = anyViewController
}, completion: nil)

We can write a generalised method too, similar to this.

You can solve this by calling setViewControllers.

Like this:

UINavigationController *navigationController = [[UINavigationController alloc] initWithNavigationBarClass:[MyNavigationBar class] toolbarClass:[UIToolbar class]];

[navigationController setViewControllers:@[yourRootViewController] animated:NO];

Swift version:

let navigationController = UINavigationController(navigationBarClass: MyNavigationBar.self, toolbarClass: UIToolbar.self)

navigationController.setViewControllers([yourRootViewController], animated: false)

this one works for me, hope it helps you,

let rootVC:LoginViewController = self.storyboard?.instantiateViewControllerWithIdentifier("LoginViewController") as! LoginViewController
let nvc:UINavigationController = self.storyboard?.instantiateViewControllerWithIdentifier("RootNavigationController") as! UINavigationController
nvc.viewControllers = [rootVC]
UIApplication.sharedApplication().keyWindow?.rootViewController = nvc

  let storyboard = UIStoryboard(name: "Main", bundle: nil)         
  let yourNewRootView = storyboard.instantiateViewControllerWithIdentifier("yourNewRootView") as? yourNewRootView


   self.window = UIWindow(frame: UIScreen.mainScreen().bounds)

    UIView.transitionWithView(self.window!, duration: 0.1, options: [UIViewAnimationOptions.TransitionFlipFromRight,UIViewAnimationOptions.TransitionFlipFromLeft], animations: 
    {
        // animation

        }, completion: { (finished: Bool) -> () in

            self.window?.rootViewController = nil
            self.window?.rootViewController = yourNewRootView
            self.window?.makeKeyAndVisible()
    })
