UITesting Xcode 7, unable to tell if UIButton is visible within UIScrollView

I am automating an app using UI Testing in Xcode 7. I have a scrollview with buttons all the way down it. Sometimes the buttons are visible sometimes they hidden too far up or down the scrollview (depending on where I am on the scrollview).

Is there a way to scroll items into view or maybe tell if they are visible or not?

Thanks
