Swift 3 let myViewController = MyViewController(nibName: “MyViewController”, bundle: nil) self.present(myViewController, animated: true, completion: nil) or push in navigation controller self.navigationController!.pushViewController(MyViewController(nibName: “MyViewController”, bundle: nil), animated: true)
Calling presentViewController presents the view controller modally, outside the existing navigation stack; it is not contained by your UINavigationController or any other. If you want your new view controller to have a navigation bar, you have two main options: Option 1.

UITabBarController { tabBarController.selectedIndex = 1 } return true } This will … Read more

If you just want to run the code yourself, this is the repo: https://github.com/ThornTechPublic/InteractiveModal This is the approach I used: View Controller You override … Read more

To retain the old style you need to modify the view controller you will be presenting like this: newViewController.modalPresentationStyle = .fullScreen This is the same … Read more
Swift AppDelegate.swift internal var shouldRotate = false func application(_ application: UIApplication, supportedInterfaceOrientationsFor window: UIWindow?) -> UIInterfaceOrientationMask { return shouldRotate ? .allButUpsideDown : .portrait } Your landscape view controller let appDelegate = UIApplication.shared.delegate as!
