SizeToFit on a UIScrollView's content size

Question

A UIView has a SizeToFit method that will make the UIView fit all of it's subviews. Is there anything like that, which will just return the size that it calculates and not modify any view's frame.

I have several subviews on a UIScrollView and I want to do SizeToFit on the scroll view's contentSize, rather than it's frame. I have to do it on the contentSize, because I don't want to increase the "real" size of the UIScrollView, and the content is loaded dynamically and asynchronously so I can't do it manually when I add the subviews to the UIScrollView.

Answer 1

Put a UIView into the UIScrollView that has the same width and height and add all subviews to IT rather than the scrollview. Then set the clipToBounds property on the scrollview to TRUE, and call sizeToFit on your UIView. You can also set the opacity of the UIView's background to 0 making it invisible, but still showing its subviews.
