Swift didReceiveRemoteNotification - Navigate to rootviewcontroller no matter where in app user is located (Now With Error Message)

Question

Upon receiving push notification in the IOS Swift app, I would like to do two things based on content in notification:

1. Either navigate to screen (deeplink) so i would have to navigate from rootviewcontroller through several screens.

2. Navigate to rootviewcontroller, no matter where the user is located in the app.

The second one I see as prerequisite for the first one.

I know that I need to place code in these two functions:

• didReceiveRemoteNotification
• didReceiveLocalNotification

Error message: 'UIViewcontroller?' does not have a member named 'navigationController'

In the file AppDelegate.swift:

func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) 
{
    println("didReceiveRemoteNotification")
    //Navigate to rootviewcontroller
    var rootViewController = self.window!.rootViewController
    let mainStoryboard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
    var setViewController = mainStoryboard.instantiateViewControllerWithIdentifier("CurrentShows")
        as ViewController

    //rootViewController.navigationController?
    //    .popToViewController(setViewController, animated: false)
}

Answer 1

Try this code In your method :

var rootViewController = self.window!.rootViewController
let mainStoryboard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)

var setViewController = mainStoryboard
    .instantiateViewControllerWithIdentifier("CurrentShows")
        as ViewController_CurrentShows

rootViewController
    .navigationController
    .popToViewController(setViewController, animated: false)
