Rendering a UIWebView into an ImageContext

Question

I am trying to capture the contents of a UIWebView including that which is not visible to the user. i.e. The whole web page even though the user is only looking at the top.<

Answer 1

It looks to me like UIWebView renders on demand (witness the checkerboard as you scroll downwards rapidly on a large page), so there won't be anything in the part of the layer below what you can reach until the user scrolls down there. The layer won't be able to write out what it doesn't have, so I don't think you'll be able to capture the whole area.

As far as scrolling, there aren't any obvious exposed API methods that I can think of to move it down. The web view seems to host a UIScrollView or something similar, which you could try to access by traversing the view hierarchy and use its scrollRectToVisible:animated:, but that doesn't sound like a good long-term solution.
