I'm loading a biggish (and javascript-heavy) page into a UIWebView, and I want to add a UIActivityView to spin while it thinks.

Problem is, my - (void)webViewDidFinishLoad:(UIWebView *)webView method gets called quite a while before the rendering actually happens. Enough so that my spinner (which set to hide when stopped) never actually shows up. By the time the UI is even assembled, the spinner has already been stopped and hidden, even though there's enough time to wonder if it's broken before the UIWebView actually gets the goods to the screen.

I wish there was a "webViewDidFinishRendering", but that would imply that WebKit is something other than lickedy-split fast... ;-)

Thoughts? Perhaps I should toss the thing up and set a timer to come stop it, and unhook that from anything that's actually happening in the WebView?
