IOS – Notification Center iOS7 bug

You could use a 3rd party calendar app just for their notification functions as a bodgy workaround.

I recommend Calvetiva, Agenda, or Tempus.

The workflow would go something like this:

1. Choose a secondary calendar app.
2. Configure you secondary calendar app to only use the calendars you want alerts for (steps vary on choice of app). Some (like Calvetica) are clever, and extend the alerts function by allowing a snooze option etc.
3. Configure secondary calendar alerts and notifications via the normal settings> notifications app to show as you want them. They will only trigger for the active calendars in the app.
4. Configure your normal calendar alerts to be off. Remove from Notification Centre, set alert style to none, and also go onto Sounds > alerts and set the calendar alert to none.

Now your existing calendar app will still have access to all calendars but won't alert, the secondary app will do alerting only for the active ones.

Downsides: You will need to periodically open and then shut the secondary calendar every so often in order for it to read the current alerts from the calendar data store and create it's own local notifications from them.

I hoped you could get round this by following the above steps but using the built in calendar as your selective alerting calendar (as it is always running and won't need to be opened to update), and using a replacement calendar app with all calendars shown but no alerts - sadly the normal Calendar app includes all calendars regardless of if you have turned a calendar off or not.

This is a bug that should be fixed, but possibly also a feature request.

The problem is simple. iOS won't remove notification from notification center when the app that post the notification launches. The developer has to tell the app to do it in order to clear all notification at app launch.

While this behavior is expected by user, developer might want finer control over when to clear the notification.

So, Mail doesn't clear the notification, and posted notification cannot be removed by app. And that ultimately result in this weird notification that links to a deleted email.

You should file a bug at Apple Bug Reporter.
