Unable to view action button for iOS 10 local notification
<p>I'm currently facing problem while viewing action buttons on time-interval notification on iOS 10. I have created two UNNotificationAction objects 'OK' &amp; 'Cancel' added as notification category. </p>

<p>I'm getting notification on simulator without any action button. Below is my code.</p>

<pre><code>let ok = UNNotificationAction(identifier: "OKIdentifier",
                                      title: "OK", options: [])

let cancel = UNNotificationAction(identifier: "CancelIdentifier",
                                  title: "Cancel",
                                  options: [])

let category = UNNotificationCategory(identifier: "message",
                                      actions: [ok, cancel],
                                      minimalActions: [ok, cancel],
                                      intentIdentifiers: [],
                                      options: [])

UNUserNotificationCenter.current().setNotificationCategories([category!])

let content = UNMutableNotificationContent()
content.title = contentTitle
content.subtitle = contentSubtitle
content.body = contentBody

let model: TimeIntervalNotificationModel = notificationsModel as!  TimeIntervalNotificationModel

trigger = UNTimeIntervalNotificationTrigger.init(timeInterval: model.timeInterval!, repeats: notificationsModel.repeats) as UNTimeIntervalNotificationTrigger

let request = UNNotificationRequest(identifier:requestIdentifier, content: content, trigger: trigger)

UNUserNotificationCenter.current().delegate = self
UNUserNotificationCenter.current().add(request){(error) in
                if (error != nil){
                    //handle here
         print("Error: Adding notification failed:\(error?.description)")

         self.delegate?.didFailToAddNotification(error: error!)
                }
            }
</code></pre>
