How to detect when a UIScrollView has scrolled all the way to the bottom?

[holyfuzz]

Hello,

How do I detect when a UIScrollView has been scrolled all the way to the bottom of its contents?

My particular use case is that I would like to show a "down arrow" graphic when the player is able to scroll further down in the scroll view, since the UI has no actually scroll bars to indicate when it can be scrolled.

Thanks!

Math. Check UIScrollView.UpdateScrollbars() function. It does the math inside.
