Your UIButtons each have a superview. For the UIButtons in the scrollview, the UIScrollView is the superview. When you have scrollView.clipsToBounds == YES, then the UIButtons in the scrollview will become obscured if you move them outside of the visible area of the scrollview.

There are several possible solutions, including:

1. Add code to change the superview of the UIButtons once they reach the edge of the scrollview (but this is tricky, and I wouldn't do it unless there was an easier option, check out Apple's UIView documentation, especially (UIView)removeFromSuperview and (UIView)addSubview:). You would have to perform this switch of superview in the code that moves the button (or tracks the move).
2. Add the UIButtons to a UIView which is the parent of the scrollview, maybe even your viewcontroller.view (but your UIButtons in the scrollview will no longer move with the scrollview upon scrolling). You would add the buttons to the view behind the scrollview, but so that they show above it.
