ios - 如何在 ios swift 中使用 xib 将 UINavigationController 设置为 rootviewcontroller？

Question

在这里，我尝试将 navigationcontroller 设置为 rootviewcontroller，但它显示错误。如何解决。

调用中的额外参数“bundle”。

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

    self.window = UIWindow(frame: UIScreen.mainScreen().bounds)
    self.window!.backgroundColor = UIColor.whiteColor()

    let nav = UINavigationController()
    let vc = MyNavigationController(nibName: "MyNavigationController", bundle: nil)

    nav.pushViewController(vc, animated: false)

    self.window!.rootViewController = nav
    self.window!.makeKeyAndVisible()
    nav.setNavigationBarHidden(true, animated: false)


    return true
}

Answer 1

var nav1 = UINavigationController()
var mainView = ViewController(nibName: nil, bundle: nil) //ViewController = Name of your controller
nav1.viewControllers = [mainView]
self.window!.rootViewController = nav1
self.window?.makeKeyAndVisible()

或

var navigationController = UINavigationController(rootViewController: viewController));
