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
}

回答：

你可以做这样的事情。

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: NSDictionary?) -> Bool {
     var rootView: MyRootViewController = MyRootViewController()
     if let window = self.window{
            window.rootViewController = rootView
     }
     return true
}
