I have a map image in a UIWebView
. It default loads in the top left hand corner. I would like it to initialize in the center of the UIWebView
.
Does anyone know how to do this?
Thanks!

Another approach is to just wrap your content in a center-aligned
div tag.
<body>
<div align="center">
<!-- Your map here -->
</div>
</body>
This will work for your solution as long as you are fine with modifying the html that you pass through to the UIWebView
. It doesn't require any javascript calls. The above solution, however, is needed if you'd prefer to inject style-sheet updates on demand and after the web page has loaded.

If the map image is the only thing in the page, is it wrapped in an html page? If it is at least wrapped in a body tag you could 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 how exactly your html is structured and then I can provide some more information if necessary.
