ok, it appears that it's a little more complicated that that. I just discovered [imageView setImageAlignment: ] which, as long as the imageView is bigger than the scrollview, does the correct thing (Lock the image to the upper left corner of the scrollView). However, when the imageView is smaller than the scrollview, The imageView is still locked to the bottom left of the scrollview, but the image is locked to the top left of the imageview. Setting the Scrollview boundsOrigin, the imageView bounds origin and translating the origin of the imageview or the scrollview had absolutely no effect. do I need to do something (other than setNeedsDisplay: YES) in order to make a translate actually happen?
