I was trying to do that a while back, and I came up with a
couple of ideas that might work, though I never got around to
trying them out.
I think the approach you want to take is to get notified when
URL load completes. The HTML parsing probably invokes a bunch
of NSURLHandle loads. NSURLHandle does have a "client"
mechanism where you can get a method invoked when its data is
available, but the problem is that you don't know in advance
what is getting loaded and therefore be notified. So you could
either fully subclass NSURLHandle, either rolling your own, or
finding another subclass that will work, like CURLHandle
<
http://curlhandle.sourceforge.net/>, and putting in a
notification mechanism. Or possibly a simpler method would be
to use class posing -- but be careful, NSURLHandle is a class
cluster, so you'd want to pose as the NSHTTPURLHandle if you can.
I'd suggestion you add a feature request at bugreport.apple.com
to come up with some notification methodology so that what you
try to do isn't as difficult as it currently is.

Hey,
So I am initializing an NSAttributed string with some rather
simple HTML and it seems images are fetched for me (though I
might not want this). I am curious, is there a way to know when
all images have been downloaded so I could refresh the view? Or
just disable this fetching altogether and perhaps do it myself?
Thanks,
