Set notifications from Today Extension Widget

Question

I am creating a simple timer application that will pay much attention to the widget features of today's extension. Users can start the timer from here by clicking.

The only problem is that I need to set a local notification from the widget. I tried using the [[UIApplicaton sharedApplication] LocalNotification] schedule, but Xcode displays a message stating that the collaborative application is not available in the application extension. Is there any solution for setting a local notification from the Today extension? Thanks in advance. Any help is appreciated.
