UIWebView Height

I am trying to get the height of the content in my UIWebView after I have loaded the content. I found this example somewhere...

NSInteger height = [[descriptionWebView stringByEvaluatingJavaScriptFromString:
                     @"document.documentElement.scrollHeight"] integerValue];

but this just gives me the height of the UIWebView container.

I am trying to get the height of the content so I can expand the UIWebView height to show all the content with no scrolling side the webview itself.

You can use the script like this:

[[descriptionWebView stringByEvaluatingJavaScriptFromString:@"document.body.scrollHeight;"] floatValue];

I would go with a kind of hacky, but reliable way. First, I watch for shouldStartLoadWithRequest. That catches location.href= changes. Then I just define my own protocol, e.g 

location.href='debug://width='+$(window).height();

Your ObjC code catches that, checks the link, parses it and cancels the navigation.

For your own content, you can just include it, otherwise you must inject the necessary javascript. I haven't tried that myself, but there appears to be lots of solutions for it:

Inject a local javascript into UIWebView
