How to clear push notifications programmatically-iOS

Question

I need to clear push notifications from notification center after the user read them. I know there is cancelAllLocalNotifications method, but how do I clear all remote notifications? As an addition I would like to have the following functionality, if user has 5 messages in notification center, we clear all notifications only after user reads All of them. Any ideas how these can be implemented? Thanks in advance for any help.

Answer 1

If you want to clear notifications in swift

import UserNotifications
if #available(iOS 10.0, *) {
 let center = UNUserNotificationCenter.current()
 center.removeAllPendingNotificationRequests() // To remove all pending notifications which are not delivered yet but scheduled.
 center.removeAllDeliveredNotifications() // To remove all delivered notifications
}

Answer 2

You can clear them using setApplicationIconBadgeNumber, e.g.:

[[UIApplication sharedApplication] setApplicationIconBadgeNumber: 0];

• Andrew: This doesn't appear to remove the notifications from the Notification Center, it just removes the badge number.
