Tells the interface controller that the user has performed a scroll-to-top gesture (for example, tapping the status bar) and that the scrolling animation has finished.
Declaration
func interfaceDidScrollToTop()Discussion
The default implementation of this method does nothing. You can override it to take actions after the scroll-to-top action completes. If the interface is already scrolled to the top, this method may be called immediately.
