making buttons change size along when zoom
===

I have a UIScrollView, with a UIImageView and UIButton inside of it.  

![enter image description here][2]

I was reading in the answers [here][1] that if I have a single view that contains all of my zoomable content, then I should be fine.  The problem is that the button doesn't zoom when the image does.

I thought that what I have would work, since the Scroll View is the zoomable view.  

Do I need to create another UIView and put everything in there (and keep the same hierarchy?) ?
