If you’re an active calendar user on iOS who relies on invitations and shared calendars, you may find it useful that iOS 8 now gives you more control over the notifications and alerts you see for different types of calendar activities. This means that you don’t need to have all of your normal event alerts, invitation alerts, and shared calendar changes notify you in the same way.
While prior iOS versions gave you the ability to simply switch things like shared calendar alerts completely off, with iOS 8 you can now fully customize each of the different categories of calendar alerts.
Simply go into your Settings app and select Notifications and then Calendar.
While the number of entries shown in the Notification Center is still set overall, you’ll see four subcategories for Upcoming Events, Invitations, Invitation Responses, and Shared Calendar Changes. Each of these allows you to customize whether they’re shown in the Notification Center or on the lock screen, as well as choose different notification sounds and alert styles — and whether that type of alert is represented by a badge count on the app icon.
