How to remove specific remote notification in the notification center

Question

We all know that this method [UIApplication sharedApplication].applicationIconBadgeNumber = 0; could remove all remote notifications of our application from the notification center. However, for some reason, I want to remove the one which user taps on the notification center, and leave the others.

Does it have any method to do it?

If you're simply looking to remove one number from the badge number:

[UIApplication sharedApplication].applicationIconBadgeNumber = MAX([UIApplication sharedApplication].applicationIconBadgeNumber - 1, 0);

If you're asking how to programmatically remove a single notification from notification center, it can't be done in code. Apparently in iOS8 the OS will remove a single notification when a user taps on it. Otherwise it's not possible to be handled by you.

Starting iOS 10, this is possible too. Check my answer https://mcmap.net/q/1294093/-how-to-remove-specific-remote-notification-in-the-notification-center – Stuyvesant

With introduction of UNUserNotificationCenter for iOS 10 and above, it is now possible to remove few or all remote notifications of your app.

UNUserNotificationCenter documentation

With a shared singleton instance of this class, it is possible to manage delivered remote notifications on the device. Specifically, the following methods can be used: func removeDeliveredNotifications(withIdentifiers: [String]) if you want to remove specific notification of your app, OR func removeAllDeliveredNotifications() to remove all notifications of your app.
