afterInterstitial is the event that is mandatory to pass to the Factory because is the one in charge of (No matter what) telling you, you can recover app flow. Because normally when you are about to call the show() method you prevent the user from taking any actions that could interrupt the interstitial or break app flow.

So for recovering this app flow and giving back control to the user you can use this event.

    class MainViewController: UiViewControlelr {
      var interstitialId:Int32 = -1;
      ...
      override func viewDidLoad() {
        super.viewDidLoad()
        ...
          let interstitialConfigId = ConfigBuilder.companion.INTERSTITIAL_TEST_R89_CONFIG_ID
          interstitialId = RefineryAdFactory.shared.createInterstitial(
          configurationID: interstitialAdId,
          uiViewController: self, 
          afterInterstitial: {
            // Here you could present the next view controller. Basically recover app flow
            self.present(NewViewController(), animated: true)
          },lifecycleCallbacks: nil)
        }
      ...
    }

Your interstitialConfigId will be provided to you during onboarding process by email, you can also retrieve them from the web interface after login.

They can be many or none depending on your requests, if you need one or more please request them to your account manager or technical account manager.

If the Interstitial hasn’t Loaded yet or failed to load when you call RefineryAdFactory.shared.show() method, afterInterstitial event will be called to recover app flow.

class MainViewController: UiViewControlelr {
      var interstitialId:Int32 = -1;
      ...
      override func viewDidLoad() {
        super.viewDidLoad()
        ...
          interstitialId = RefineryAdFactory.shared.createInterstitial(...)
        ...
          // Set up an action on uiButton to display loaded interstitial with it's interstitialId. 
          uiButton.addAction(UIAction(handler: {_ in
            RefineryAdFactory.shared.show(index: interstitialId)
          }), for: .touchUpInside)
        }
      ...
    }

This will increase the time it takes to show the interstitial and then recover app flow.

Because its making the ad request when the user takes the action. You should use the previous approach where we make the request and store the ad Id for instant showing it when the user performs the actions.

This is how we use Interstitial we use in demos because it’s pretty good at showing that it works but nothing more.

class MainViewController: UiViewController {
      ...
      override func viewDidLoad() {
        super.viewDidLoad()
        ...
          // Set up an action on uiButton to display loaded interstitial with it's interstitialId. 
          uiButton.addAction(UIAction(handler: {_ in
            createInterstitial()
          }), for: .touchUpInside)
      }
      ...
}

class MainViewController: UiViewControlelr {
      override func viewDidLoad() { ... }
      ...
      func createInterstitial(){
        let interstitialConfigId = ConfigBuilder.companion.INTERSTITIAL_TEST_R89_CONFIG_ID
        interstitialId = RefineryAdFactory.shared.createInterstitial(
        configurationID: interstitialConfigId, 
        uiViewController: self, 
        afterInterstitial: {
            // Here the navigation flow continus
            self.present(NewViewController(), animated: true)
        }, 
        lifecycleCallbacks: InterstitialEventListenerDelegate(viewController: self))
      }
    }
    
class InterstitialEventListenerDelegate : InterstitialEventListener {
    let viewController:LunchScreenViewController
    init(viewController: LunchScreenViewController) {
        self.viewController = viewController
    }
    // We need to call show on the onLoaded event and on the OnFailedToLoad event,
    // this is to show the ad in both cases so the afterInterstitial event is called
    override func onLoaded() {
        RefineryAdFactory.shared.show(index: viewController.interstitialId)
    }
    override func onFailedToLoad(error: R89LoadError) {
        RefineryAdFactory.shared.show(index: viewController.interstitialId)
    }
    ...
}
