Opening view controller from app delegate using sw

Question

I am trying to create a push notification which determines which view to open according to information obtained from the push.

I have managed to get the information from the push, but I am now struggling to get the view to open

Looking at other stack overflow questions I have the following currently:

App Delegate Did finish loading:

     //Extract the notification data
    if let notificationPayload = launchOptions?[UIApplicationLaunchOptionsRemoteNotificationKey] as? NSDictionary {
        // Get which page to open
        let viewload = notificationPayload["view"] as? NSString
        let storyBoard : UIStoryboard = UIStoryboard(name: "Main", bundle:nil)
        //Load correct view
        if viewload == "circles" {

            var viewController = self.window?.rootViewController?.storyboard?.instantiateViewControllerWithIdentifier("Circles") as! UIViewController
            self.window?.rootViewController = viewController

                        }
    }

Currently this is failing on the var ViewController = self... line.

Answer 1

let storyboard = UIStoryboard(name: "Main", bundle: nil)

    let destinationViewController = storyboard.instantiateViewController(withIdentifier: "LandVC") as! LandingPageVC

    destinationViewController.webpageURL = NotificationAdvertisement._htmlpackagePath
    destinationViewController.adID = NotificationAdvertisement._adID
    destinationViewController.toneID = NotificationAdvertisement.toneID

    let navigationController = self.window?.rootViewController as! UIViewController

    navigationController.showDetailViewController(destinationViewController, sender: Any?.self)

You have to set ViewController StoryBoardId property as below image.

open viewController using coding as below in swift

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

         let mainStoryboardIpad : UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
         let initialViewControlleripad : UIViewController = mainStoryboardIpad.instantiateViewControllerWithIdentifier("Circles") as UIViewController
         self.window = UIWindow(frame: UIScreen.main.bounds)
         self.window?.rootViewController = initialViewControlleripad
         self.window?.makeKeyAndVisible()

         return true
    }

Swift 3 SWRevealViewController

    self.window = UIWindow(frame: UIScreen.main.bounds)
    let storyBoard = UIStoryboard(name: "Main", bundle: nil)

    let viewController = storyBoard.instantiateViewController(withIdentifier: "SWRevealViewController") as! SWRevealViewController
    self.window?.rootViewController = viewController
    self.window?.makeKeyAndVisible()

SWIFT 4

let storyboard = UIStoryboard(name: "Main", bundle: nil)

    let destinationViewController = storyboard.instantiateViewController(withIdentifier: "LandVC") as! LandingPageVC

    destinationViewController.webpageURL = NotificationAdvertisement._htmlpackagePath
    destinationViewController.adID = NotificationAdvertisement._adID
    destinationViewController.toneID = NotificationAdvertisement.toneID

    let navigationController = self.window?.rootViewController as! UIViewController

    navigationController.showDetailViewController(destinationViewController, sender: Any?.self)

In Swift 3

        let mainStoryboardIpad : UIStoryboard = UIStoryboard(name: StorybordName, bundle: nil)
        let initialViewControlleripad : UIViewController = mainStoryboardIpad.instantiateViewController(withIdentifier: identifierName) as UIViewController
        if let navigationController = self.window?.rootViewController as? UINavigationController
        {
            navigationController.pushViewController(initialViewControlleripad, animated: animation)
        }
        else
        {
            print("Navigation Controller not Found")
        }

First Initialize the window

self.window = UIWindow(frame: UIScreen.mainScreen().bounds)
let storyBoard = UIStoryboard(name: "Main", bundle: nil)

For setting rootViewController inside AppDelegate Class

let viewController = storyBoard.instantiateViewControllerWithIdentifier("Circles") as UIViewController
self.window?.rootViewController = viewController
self.window?.makeKeyAndVisible()
