How do I include CSS resource in programmatically generated HTML for iPhone UIWebView?

Question

I am programmatically generating HTML and want to link to a CSS file that I've included in my Resources folder. I am using a baseURL of nil, and my CSS file is at the top level of the project file, but this "link" is definitely not working (ie, the CSS file is clearly not being loaded/found when the UIWebView displays the HTML).

Is it possible to do this? Or will I need to put the CSS file on the web somewhere and link to it via a URL? (I can see the advantage of doing this -allowing the app to change its style without redistributing the app).

Thanks

Answer 1

Thanks everyone! Here's what I did, works great.

NSBundle *bundle = [NSBundle mainBundle];
NSURL *resourceBaseURL = [NSURL fileURLWithPath:[bundle bundlePath]];
[self.webView loadHTMLString:htmlString baseURL:resourceBaseURL];

Set the base URL to the bundle path:

NSBundle *bundle = [NSBundle mainBundle];
NSURL *baseURL = [NSURL fileURLWithPath:[bundle bundlePath]];
