Sounds like you're not going to be able to use a UIWebView for your preview.
ImageIO can read Canon RAW images. Create a CGImageSource with the
file's URL and you'll be able to get a CGImage out of it. You can then
wrap it in a UIImageView and display it in a preview UI, or otherwise
use it as you would any other CGImage.
