You can solve this by calling setViewControllers.
您可以通过调用来解决此问题setViewControllers。
Like this:
像这样：
UINavigationController *navigationController = [[UINavigationController alloc] initWithNavigationBarClass:[MyNavigationBar class] toolbarClass:[UIToolbar class]];
[navigationController setViewControllers:@[yourRootViewController] animated:NO];
Swift version:
迅捷版：
let navigationController = UINavigationController(navigationBarClass: MyNavigationBar.self, toolbarClass: UIToolbar.self)
navigationController.setViewControllers([yourRootViewController], animated: false)

Changing root view controller from class other than app delegate.swift
从 app delegate.swift 以外的类更改根视图控制器
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 achieve with:
使用动画更改 rootviewcontroller 可以通过以下方式实现：
UIView.transitionWithView(self.window!, duration: 0.5, options: UIViewAnimationOptions.TransitionFlipFromLeft, animations: {
self.window?.rootViewController = anyViewController
}, completion: nil)
We can write generalise method too similar to this.

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()
})
