I have some code that needs to run after the a UIWebView finishes loading a document. For that I've set the UIWebView's delegate to my controller, and implemented the webViewDidFinishLoading method.

This gets called multiple times, depending on the type of page to load. I'm not sure if it's because of ajax requests, requests for images, or maybe even iframes.

Is there a way to tell that the main request has finished, meaning the HTML is completely loaded?

Or perhaps delay my code from firing until all of those events are done firing?

You can do something like this to check when loading is finished. Because you can have a lot of content on the same page you need it.

- (void)webViewDidFinishLoad:(UIWebView *)webview  {
    if (webview.isLoading)
        return;
    // do some work
}
