iOS Push Notifications don't adds to Notification Center

Question

I realizing push notification handling on my iOS application on Xamarin.iOS platform but my problem actual for iOS native too.
I need to handle push notification when my application is in Background Mode for some reasons, so I turn on Background Mode and Push Notification using in my project. Also I include the content-available key with a value of 1 into the payload's aps dictionary. Also I include alert , badge and sound keys because I want to show this push notification for user and add it into Notification Center.

As a result after push notification receiving in Background Mode (when application is not active):
1) I handle push notification receiving using DidReceiveRemoteNotification() method.
2) The user see notification rolls down from the top of the screen as a banner.
3) I change application icon badge counter.
My problem is that push notification don't adds to Notification Center after all this actions.
As I understand after handling the push notification in DidReceiveRemoteNotification() method iOS mark this notification like handled and doesn't add them to Notification Center. As possible solution I can create Local Notification, schedule them and it'll added to Notification Center but the user will again see notification rolls down from the top of the screen as a banner and that's not good (it looks like user gets 2 notifications but only 1 shows in Notification Center).
What's the actual reason for this behaviour and how can I solve this problem?

You can try VoIP Push notification Service.

- (void)pushRegistry:(PKPushRegistry *)registry didReceiveIncomingPushWithPayload:(PKPushPayload *)payload forType:(NSString *)type
     NSDictionary *payloadInfo = payload.dictionaryPayload;
     [self showLocalNotificationWithInfo: payloadInfo];
}

- (void) showLocalNotificationWithInfo:(NSDictionary *)infoDict{
     UILocalNotification* localNotification = [[UILocalNotification alloc] init];
     localNotification.fireDate = [NSDate date];
     localNotification.alertBody = @"Your title message";

     localNotification.soundName = @"YourSoundFileName.mp3";
     localNotification.userInfo = userInfo;
     localNotification.fireDate = [NSDate date];
     localNotification.timeZone = [NSTimeZone systemTimeZone];
     localNotification.applicationIconBadgeNumber = [[UIApplication sharedApplication] applicationIconBadgeNumber] + 1;
     [[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
}

Thank you guys for your answers. I found a reason of this behavior - the problem was with badge key in push notification body. This key had 0 value and thats why iOS marked new notifications as readed and they didn't add to Notification Center.
