我想在应用程序委托中设置rootViewController ..

func application(application: UIApplication,didFinishLaunchingWithOptions launchOptions: NSDictionary?) -> Bool {

     var rootView: MyRootViewController = MyRootViewController()
     //Code to set this viewController as the root view??


     return true

}

你可以这样做。

func application(application: UIApplication,didFinishLaunchingWithOptions launchOptions: NSDictionary?) -> Bool {

     var rootView: MyRootViewController = MyRootViewController()

     if let window = self.window{
            window.rootViewController = rootView
     }

     return true
}
