Scale image to fit screen on iPhone rotation

Question

Try this:

scrollView.autoresizingMask = (UIViewAutoresizingFlexibleWidth |
                           UIViewAutoresizingFlexibleHeight);    
imageView.autoresizingMask = (UIViewAutoresizingFlexibleWidth |
                           UIViewAutoresizingFlexibleHeight);

imageView.contentMode = UIViewContentModeAspectFit; // You could also try UIViewContentModeCenter

I'm not sure if the imageView will get automatically resized within a UIScrollView, so if the autoresizing doesn't work, you could try setting the frame yourself on rotate to equal the size of the scrollview.
