Today Extension
scroll is disabled
Adding scrolls into a widget, both vertical and horizontal, is not possible. Or more precisely, adding a scroll view is possible but scrolling won’t work. Horizontal scrolling gesture in a scroll view in the Today extension will be intercepted by the notification center which will cause scrolling from Today to the Notification center. Scrolling vertically a scroll view inside a Today extension will be interrupted by scrolling the Today’s View.
