ios - Swift - How to attach bar to the top of table view?

Question

I've got a table view which is situated on top of mapview. It looks like that:

I wonder how to attach some kind of bar on top of the table view so it indicates that the table is scrollable. Something like thin bar with arrow directed up. I don't have appropriate asset at the moment, but I'd like to know how to do that. I failed to find such thread in the forum.

Doing it in storyboard could be tedious since the table view covers all of the area of main view. So I guess it would be easier to do that by programmatic apprach.

Could you suggest how to approach such problem?

Thanks in advance.

You can show them momentarily when the table view shows on the screen with flashScrollIndicators() check here : https://developer.apple.com/library/ios/documentation/UIKit/Reference/UIScrollView_Class/index.html#//apple_ref/occ/instm/UIScrollView/flashScrollIndicators
