UIWebView loadHTMLString format

Question

Hi,

I'm new to the whole "iPhone Dev" world, and I am creating a simple app which has a feature to see the latest entries from a number of different Wordpress blogs.

I am able to grab encoded content ( node) from the RSS feeds and display it easily enough using a UIWebView and the loadHTMLString function.

What I cannot figure out how to do right now is change the look of the text in any way, shape, or form... I don't think it's possible for me to change the data coming back in the RSS feed, so I need to know how to do it in the code.

Thanks!

There are at least two ways to change the appearance.

One is to modify the html before passing it to loadHTMLString. For example, you could insert a <link href="local.css" rel="stylesheet" type="text/css"> just before </head> using simple string replacement. You could do the same thing with a <style>...</style> tag.

html = [html stringByReplacingOccurrencesOfString:@"</head>" withString:@"<link ... /></head>"];

Another way is to call stringByEvaluatingJavaScriptFromString in webViewDidFinishLoad and do whatever you want with javascript. You have full access to the DOM through javascript and can manually create styles and assign classes.

You may need to use both together.
