Notificación interactiva: botones que no se muestran (locales o remotos)

Seguí muchos tutoriales sobre notifications interactivas y no sé qué falta en mi código. Puedo recibir una simple notificación push y sé que tengo que deslizar para que aparezcan los botones. Tengo un iPhone 4S en iOS 9.2.1 y uso Mixpanel para enviar una notificación. También probé la notificación local, pero tampoco funciona. (simulador 8.4, 9.2, iPhone 4S) Tengo el post, pero no hay botones.

Carga útil: { "aps" : { "category" : "RATING_CATEGORY", "alert" : "rate the app" }}

AppDelegate:

  func registerForNotifications() { if #available(iOS 8.0, *) { let notificationActionRate :UIMutableUserNotificationAction = UIMutableUserNotificationAction() notificationActionRate.identifier = "RATE_IDENTIFIER" notificationActionRate.title = NSLocalizedString("Rate.Button.Title", comment: "Rate the app") notificationActionRate.destructive = false notificationActionRate.authenticationRequinetworking = false notificationActionRate.activationMode = UIUserNotificationActivationMode.Background let notificationActionNotNow :UIMutableUserNotificationAction = UIMutableUserNotificationAction() notificationActionNotNow.identifier = "NOT_NOW_IDENTIFIER" notificationActionNotNow.title = NSLocalizedString("NotNow.Button.Title", comment: "Not now") notificationActionNotNow.destructive = true notificationActionNotNow.authenticationRequinetworking = false notificationActionNotNow.activationMode = UIUserNotificationActivationMode.Background let notificationCategoryRating: UIMutableUserNotificationCategory = UIMutableUserNotificationCategory() notificationCategoryRating.identifier = "RATING_CATEGORY" notificationCategoryRating.setActions([notificationActionRate, notificationActionNotNow], forContext: UIUserNotificationActionContext.Default) notificationCategoryRating.setActions([notificationActionRate, notificationActionNotNow], forContext: UIUserNotificationActionContext.Minimal) let categories = Set([notificationCategoryRating]) UIApplication.shanetworkingApplication().registerUserNotificationSettings(UIUserNotificationSettings(forTypes: [.Sound, .Alert, .Badge], categories: categories)) UIApplication.shanetworkingApplication().registerForRemoteNotifications() } else { UIApplication.shanetworkingApplication().registerForRemoteNotificationTypes([.NewsstandContentAvailability, .Badge,.Sound,.Alert]) } } func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool { registerForNotifications() return true } func application(application: UIApplication, handleActionWithIdentifier identifier: String?, forRemoteNotification userInfo: [NSObject : AnyObject], completionHandler: () -> Void) { if identifier == "RATE_IDENTIFIER" { let itunesLink = NSURL(string: "http://google.com") UIApplication.shanetworkingApplication().openURL(itunesLink!) } completionHandler() }
