cancelAllLocalNotifications not working in iOS10

Question

I want to remove all previous local notification from NotificationCenter when adding new notifications. But it is working in iOS9.0 and lower version but in iOS 10 it fires

Answer 1

For iOS 10, Objective C:

UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
[center removeAllDeliveredNotifications];
[center removeAllPendingNotificationRequests];

Swift 4:

UNUserNotificationCenter.current().removeAllPendingNotificationRequests()

If you want to list all notifications:

func listPendingNotifications() {

    let notifCenter = UNUserNotificationCenter.current()
    notifCenter.getPendingNotificationRequests(completionHandler: { requests in
        for request in requests {
            print(request)
        }
    })
}
