Programmatically delete Remote Notifications from Notification Centre

Question

How can we pragmatically remove any pending remote notifications sent for my app from notification centre. I want to clear them up on app launch.

I have tried with [[UIApplication sharedApplication] cancelAllLocalNotifications]; API but its not helping.

PS: This question is specific to iOS 10 and old threads are not duplicates for this one.

@SargisGevorgyan This cannot be marked as duplicate as the shared link talks about non-iOS 10 solution. iOS 10 handles it in a different way! — Abhinav, May 12 '17 at 11:07

You can clear all notifications from notification centre by using these simple lines of code

[[UIApplication sharedApplication] setApplicationIconBadgeNumber: 1];
[[UIApplication sharedApplication] setApplicationIconBadgeNumber: 0];
[[UIApplication sharedApplication] cancelAllLocalNotifications];

use wherever you want. From my side I have used when user pressed logout. You can use in

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

method to clear notifications after app opens

I had tried this already and its not helping. I am talking about remote notifications here. May be I should edit my question. – Abhinav May 12 '17 at 10:43
the line [UIApplication sharedApplication].applicationIconBadgeNumber=0; will clear push notifications as well – Himanth May 12 '17 at 10:47
Thats not true! – Abhinav May 12 '17 at 10:49

AFAIK, you should do it by using the background mode for remote notifications, and then responding to these notifications by issuing a local notifications. You can remove local notifications, but not remote notifications.

Thank you for your response. Could you please point me to documentation which confirms that remote notifications cannot be removed from Notification Centre? I am finding multiple versions online. – Abhinav May 12 '17 at 10:54
Can't find the official doc on this yet, but you can have a look here for now: http://stackoverflow.com/questions/24231120/remove-remote-notification-from-notification-center – Mehul Parmar May 12 '17 at 10:59

Reseting the application badge number also remove all the notifications (local & remote) from the notification center.

Objective C

[UIApplication sharedApplication].applicationIconBadgeNumber = 0;

Swift

UIApplication.shared.applicationIconBadgeNumber = 0

Is there a way to reset the badge count WITHOUT deleting all notifications? – fabb Nov 17 '17 at 10:06

This can definitely be achieved by using removeDeliveredNotifications(withIdentifiers:) method available in UserNotifications.framework.
