The buttons I'm referring to are the ones you see in the default photo app for iphone. I didn't see them in the docs, but it seems like they should be there somewhere.
Look in the kitchensink examples. Try the one for Scrollview "scroll_view_scrollable.js" I think that's the one that has the buttons you're looking for.
That is a good example of what I'm looking for, but those arrows are non native images. However, it looks like the SDK automagically adds the flare effect to them when clicked which was what I was really hoping for. So not an ideal solution, but it'll work.
