Answer 1

What about using the window.onload or jQuerys $(document).ready event to trigger the shouldStartLoad callback?

Something like:

$(document).ready(function(){
    location.href = "app://do.something"
})

and in your UIWebViewDelegate do something like:

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
{
    NSURL *url = request.URL;

    if([url.host isEqualToString:@"app"]){
        //maybe check for "do.something"
        //at this point you know, when the DOM is finished
    }
}

With this method you can forward every possible event from the JS code to your obj-c code.

Hope that helps. The code sample is written in the browser, and therefore not tested! ;-)
