Detect Other Button click (NSUserNotification)

Question

I've searched all over the internet but the only method found was by looping through

- (void)userNotificationCenter:(NSUserNotificationCenter *)center didDeliverNotification:(NSUserNotification *)notification

just as shown in: https://stackoverflow.com/a/21365269/1795083

However, my app sometimes displays multiple notifications at a short interval, so this isn't really efficient nor effective. How does the mail app handle it when the trash button is pressed. There has to be at least a private method that's called. Has anyone ever came across it? Thanks in advance

After... uhm.... "checking" out the mail app's code... I found a suspicious function in their notification controller class...

- (void)userNotificationCenter:(NSUserNotificationCenter *)center didDismissAlert:(NSUserNotification *)alert

I have no idea why apple don't want to add this function to the NSUserNotificationDelegate... but I tested this out in my app and it works!!!

Yeah, that works. I wonder if it could get your app reject from MAS. – Vojto May 03 '17 at 07:13
Where/how can you get Mail app code? Have you reverse engineered it? – Vito Valov Sep 29 '17 at 23:57
@VitoValov yep I reverse engineered the binary using Hopper Disassembly – Brave Heart Sep 30 '17 at 03:19

Swift >= 4 version:

@objc
func userNotificationCenter(_ center: NSUserNotificationCenter, didDismissAlert notification: NSUserNotification)

Make sure you add the @objc annotation, otherwise the objective-C runtime won't be able to see your delegate method.
