Use contentInset (see What's the UIScrollView contentInset property for?). Additionally, you might want to move the view that contains your other items within the UIScrollView to the new zero point (by setting its frame), but I don't think that's what you're looking for.

The contentOffset is relevant, too, if you need to scroll to that point programmatically.
