首次启动后，本地通知（UIUserNotificationActionContext.Minimal）不会在模拟器中显示操作

Question

我有本地通知，我有两种要执行的操作，我希望在用户收到通知时显示这些操作。

相关代码：

的AppDelegate：

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool
{
    ......

    //local notifications part
    let completeAction = UIMutableUserNotificationAction()
    completeAction.identifier = "COMPLETE" // the unique identifier for this action
    completeAction.title = "Complete" // title for the action button
    completeAction.activationMode = .Background // UIUserNotificationActivationMode.Background - don't bring app to foreground
    completeAction.authenticationRequired = false // don't require unlocking before performing action
    completeAction.destructive = true // display action in red

    let callInAction = UIMutableUserNotificationAction()
    callInAction.identifier = "CALLIN"
    callInAction.title = "Call in"
    callInAction.activationMode = .Background
    callInAction.destructive = false

    let notificationCategory = UIMutableUserNotificationCategory() // notification categories allow us to create groups of actions that we can associate with a notification
    notificationCategory.identifier = "CALLINNOTIFICATION"
    notificationCategory.setActions([callInAction, completeAction], forContext: .Default) //UIUserNotificationActionContext.Default (4 actions max)
    notificationCategory.setActions([callInAction, completeAction], forContext: .Minimal) //UIUserNotificationActionContext.Minimal - for when space is limited (2 actions max)

    application.registerUserNotificationSettings(UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: Set<UIUserNotificationCategory>.init(arrayLiteral: notificationCategory))) // we're now providing a set containing our category as an argument

    return true
}

func application(application: UIApplication, handleActionWithIdentifier identifier: String?, forLocalNotification notification: UILocalNotification, completionHandler: () -> Void) {
    //var item = TodoItem(deadline: notification.fireDate!, title: notification.userInfo!["title"] as String, UUID: notification.userInfo!["UUID"] as String!)
    switch (identifier!) {
    case "COMPLETE":
        print("complete")
       //do nothing for now
    case "CALLIN":
        print("gonnacall")
        let call = Call()
        call.withDevicePhone(method: Call.AS.UNDEFINED)

    default: // switch statements must be exhaustive - this condition should never be met
        print("Error: unexpected notification action identifier: \(identifier)")
    }
    completionHandler() // per developer documentation, app will terminate if we fail to call this
}

安排通知方法：

func scheduleLocalNotifications() {
....
if(event.startTime.timeIntervalSinceDate(NSDate()) > 0 && limitCounter <= 64){

                    let notification = UILocalNotification()
                    let minutesBefore = CallIn.Settings.notifyNumberOfMinutesBeforeEvent
                    notification.fireDate = event.startTime.dateByAddingTimeInterval(-minutesBefore * 60) //time of launch of notification

                    if(minutesBefore <= 1){
                        notification.alertBody = "Your \(event.title) is about to start"
                    }else{
                        notification.alertBody = "You have \(event.title) in \(Int(minutesBefore)) minutes"
                    }
                    notification.alertAction = "OK"
                    notification.soundName = UILocalNotificationDefaultSoundName
                    notification.userInfo = ["title": event.title, "UUID": event.UUID, "CallIn": "CallInNotification"]
                    notification.category = "CALLINNOTIFICATION"
                    notification.applicationIconBadgeNumber = 1

                    UIApplication.sharedApplication().scheduleLocalNotification(notification)
                    limitCounter += 1
                }
.....
}

当我重置模拟器的内容和设置时，在第一次启动时，我会得到两种类似的操作：

但是从第二次启动开始，我从未得到动作（不是处于锁定状态，不是通知列表，不是弹出警报样式）：
