ios - passing - Cómo navegar de un controlador de vista a otro usando Swift

pasar de una pantalla a otra swift

Question

Me gustaría navegar de un controlador de vista a otro. ¿Cómo puedo convertir el siguiente código Objective-C en Swift?

UIViewController *viewController = [[self storyboard] instantiateViewControllerWithIdentifier:@"Identifier"];
UINavigationController *navi = [[UINavigationController alloc] initWithRootViewController:viewController];
[self.navigationController pushViewController:navi animated:YES];

Answer 1

Cree un archivo rápido (SecondViewController.swift) para el segundo controlador de vista y en la función apropiada escriba esto:

let secondViewController = self.storyboard.instantiateViewControllerWithIdentifier("SecondViewController") as SecondViewController
self.navigationController.pushViewController(secondViewController, animated: true)

Swift 2+

let mapViewControllerObj = self.storyboard?.instantiateViewControllerWithIdentifier("MapViewControllerIdentifier") as? MapViewController
self.navigationController?.pushViewController(mapViewControllerObj!, animated: true)

Swift 4

let vc = UIStoryboard.init(name: "Main", bundle: Bundle.main).instantiateViewController(withIdentifier: "IKDetailVC") as? IKDetailVC
self.navigationController?.pushViewController(vc!, animated: true)

Answer 2

En Swift 4.1 y Xcode 9.3

Aquí AddFileViewController es el segundo controlador de vista.

La ID del guion gráfico es AFVC

let next = self.storyboard?.instantiateViewController(withIdentifier: "AFVC") as! AddFileViewController
self.present(next, animated: true, completion: nil)
//OR
let dashboard = self.storyboard?.instantiateViewController(withIdentifier: "DBVC") as! DashboardViewController
self.navigationController?.pushViewController(dashboard, animated: true)

Answer 3

En mi experiencia, navigationController era nulo, así que cambié mi código a este:

let next = self.storyboard?.instantiateViewControllerWithIdentifier("DashboardController") as! DashboardController
self.presentViewController(next, animated: true, completion: nil)

No olvides configurar ViewController StoryBoard Id en StoryBoard -> identity inspector

En veloz 3

let nextVC = self.storyboard?.instantiateViewController(withIdentifier: "NextViewController") as! NextViewController
self.navigationController?.pushViewController(nextVC, animated: true)

Answer 5

En veloz 4.0

var viewController: UIViewController? = storyboard().instantiateViewController(withIdentifier: "Identifier")
var navi = UINavigationController(rootViewController: viewController!)
navigationController?.pushViewController(navi, animated: true)

Answer 6

Si no desea que aparezca el botón Atrás (que era mi caso, porque quería presentarlo después de que un usuario inició sesión), aquí se explica cómo configurar la raíz del controlador de navegación:

let vc = self.storyboard?.instantiateViewControllerWithIdentifier("YourViewController") as! YourViewController
let navigationController = UINavigationController(rootViewController: vc)
self.presentViewController(navigationController, animated: true, completion: nil)

Answer 7

SWIFT 3.01

let secondViewController = self.storyboard?.instantiateViewController(withIdentifier: "Conversation_VC") as! Conversation_VC
self.navigationController?.pushViewController(secondViewController, animated: true)

Answer 8

Swift 3

let secondviewController:UIViewController = self.storyboard?.instantiateViewController(withIdentifier: "StoryboardIdOfsecondviewController") as? SecondViewController
self.navigationController?.pushViewController(secondviewController, animated: true)

Answer 9

let objViewController = self.storyboard?.instantiateViewController(withIdentifier: "ViewController") as! ViewController
self.navigationController?.pushViewController(objViewController, animated: true)
