How to focus UIWebView content on iPhone

I have a map image in UIWebView. It loads by default in the upper left corner. I would like it to be initialized in the center UIWebView.

Does anyone know how to do this?

Thank!

If the map image is the only thing on the page, is it wrapped in an html page? If it is at least wrapped in a body tag, you can do the following:

NSString *bodyStyle = @"document.getElementsByTagName('body')[0].style.textAlign = 'center';";
NSString *mapStyle = @"document.getElementById('mapid').style.margin = 'auto';";

[webView stringByEvaluatingJavaScriptFromString:bodyStyle];
[webView stringByEvaluatingJavaScriptFromString:mapStyle];

Let me know exactly how your html is structured, and then I can provide additional information if necessary.
