I\'ve searched all over the internet but the only method found was by looping through
- (void)userNotificationCenter:(NSUserNotificationCenter *)center didDe
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!!!
