iphone - UIWebView: when did a page really finish loading?

Question

I need to know, when a web page has completely been loaded by UIWebView. I mean, really completely, when all redirects are done and dynamically loaded content is ready. I tried injecting javascript (querying for document.readyState == 'complete'), but that does not seem to be very reliable.

Is there, maybe, an event from the private api that will bring me the result?

I have been looking for the answer for this, and I got this idea from Sebastian's question. Somehow it works for me, maybe it will for those who encounter this issue.

I set a delegate to UIWebView and in the webViewDidFinishLoad, I detect if the webview has really finished loading by executing a Javascript.

- (void)webViewDidFinishLoad:(UIWebView *)webView {
    if ([[webView stringByEvaluatingJavaScriptFromString:@"document.readyState"] isEqualToString:@"complete"]) {
        // UIWebView object has fully loaded.
    }
}
