Using 3D Touch in my application

Question

So i am trying to add 3D Touch on my application icon using shortCutItems. Here is my AppDelegate.swift:

import UIKit
import Parse

//MARK: - Handle QuickActions For ShorCut Items -> AppDelegate Extension
@available(iOS 9.0, *)
typealias HandleForShorCutItem = AppDelegate
@available(iOS 9.0, *)
extension HandleForShorCutItem {

    /// Define quick actions type
    enum QuickActionsType: String {
        case JegHarAldri =     "JEGHARALDRI"
        case Pling =   "PLING"
        case FlasketutenPekerPå =    "FLASKETUTENPEKERPÅ"
        case KortetTaler =  "KORTETTALER"
    }
}

@available(iOS 9.0, *)
@UIApplicationMain

    var window: UIWindow?

    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
        // Override point for customization after application launch.

        Parse.setApplicationId("XX",
            clientKey: "XX")

        // Register for Push Notitications
        if application.applicationState != UIApplicationState.Background {
            // Track an app open here if we launch with a push, unless
            // "content_available" was used to trigger a background push (introduced in iOS 7).
            // In that case, we skip tracking here to avoid double counting the app-open.

            let preBackgroundPush = !application.respondsToSelector("backgroundRefreshStatus")
            let oldPushHandlerOnly = !self.respondsToSelector("application:didReceiveRemoteNotification:fetchCompletionHandler:")
            var pushPayload = false
            if let options = launchOptions {
                pushPayload = options[UIApplicationLaunchOptionsRemoteNotificationKey] != nil
            }
            if (preBackgroundPush || oldPushHandlerOnly || pushPayload) {
                PFAnalytics.trackAppOpenedWithLaunchOptions(launchOptions)
            }
        }

        let handledShortCutItem = QuickActionsForItem(shortcutItem)
        completionHandler(handledShortCutItem)
    }
}

I have some issues. FYI! I do not have a tabBarController in my project.

When i open my application using the 3D Touch items, it freezes for 4-5 seconds before it opens the application. When the application is opened, the back buttons does not work.

So is there any possible ways to open the app on the initial controller, and perform segue to the correct view controller?

Answer 1

 private func showViewController(viewControllerKey: ViewControllerKeys) -> Bool
{
    // Init the storyboard
    let storyboard = UIStoryboard(name: "Main", bundle: nil)

    // Init the root navigationController
    guard let navigationController = storyboard.instantiateInitialViewController() as? UINavigationController else { return false }
    // Set the root navigationController as rootViewController of the application
    UIApplication.sharedApplication().keyWindow?.rootViewController = navigationController

    // Init the wanted viewController
    guard let viewController = storyboard.instantiateViewControllerWithIdentifier(viewControllerKey.rawValue) else { return false }
    // Push this viewController
    navigationController.pushViewController(viewController, animated: false)

    return true
}
