//Swift
let viewController = UIViewController()
let navigationController = UINavigationController(rootViewController: viewController)

//Objective-C
UIViewController *viewController = [[UIViewController alloc] init];
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:viewController];
