You could use the delegate method webViewDidFinishLoad: but sometimes this is called before the HTML is fully rendered and that leads to wrong height values.

To make this work reliably you have to wait until the HTML is fully rendered and then use Javascript to send the correct height to your UIWebView.

Please have a look at this blogpost I wrote some time ago.

Do it with your web view's delegate method :

- (void)webViewDidFinishLoad:(UIWebView *)webView
{
    webView.frame = CGRectMake(0, 0, webView.scrollView.contentSize.width, webView.scrollView.contentSize.height);
}

set your web view delegate and frame.

 yourwebview.frame=[[UIScreen mainScreen] bounds]; 
 yourwebview.delegate = self;

end then use this delegate method to set height.

- (void)webViewDidFinishLoad:(UIWebView *)aWebView {
        CGSize contentSize = aWebView.scrollView.contentSize;
        NSLog(@"webView contentSize: %@", NSStringFromCGSize(contentSize));
        yourwebview.contentsize = contentSize;
    }
