I believe what you're looking to do can be accomplished using a UIScrollView. When you've got a UIImageView embedded in a UIScrollView, it can perform the panning/zooming you mentioned in your question.

See UIScrollView documentation: http://developer.apple.com/library/ios/#documentation/uikit/reference/UIScrollView_Class/Reference/UIScrollView.html

Also, here is a thread I found here on StackOverflow that lists several tutorials to help you get started: Are there any good UIScrollView Tutorials on the net?
