how do I get the title of a URL

I have a URL and I will show the URL inside a ModalViewController. I would like to set the开发者_如何学JAVA title of this URL in the navigation bar.

Inside the ModalViewController I have a UIWebView to display the site. Is there a way to extract the title of this site via UIWebView? Did a bit of research and it seems that I would like to use some javascript inside the (void)webViewDidFinishLoad:(UIWebView *)webView Not sure though how it works.

Try this:

- (void)webViewDidFinishLoad:(UIWebView *)webView
{
    NSString* title = [webView stringByEvaluatingJavaScriptFromString: @"document.title"];
    navbar.title = title;
}
