Load resources from relative path using local html in uiwebview

I have a very simple iOS app with a uiwebview loading a very simple test page (test.html):

<html>
<body>
<img src="img/myimage.png" />
</body>
</html>

I load this test.html file into my web view:

NSURL *url = [[NSBundle mainBundle] URLForResource:@"test" withExtension:@"html"];
NSString *html = [NSString stringWithContentsOfURL:url encoding:NSUTF8StringEncoding error:nil];
NSURL *baseUrl = [NSURL fileURLWithPath:[[NSBundle mainBundle] bundlePath]];
[webView loadHTMLString:html baseURL:baseUrl];

This works fine if I reference the image without the relative path and put the referenced image in the root path under Targets -> Copy Bundle Resources within XCode, however I can't get it to work with the relative path as shown in my html file. There must be a way to do this, I have lots of images, css, javascript files that I want to load into the webview and I would like not to have to have everything in the root and have to change all the references in my web app.

I simply do this:

    UIWebView *webView = [[[UIWebView alloc] init] autorelease];

    NSURL *url = [[NSBundle mainBundle] URLForResource:@"index" withExtension:@"html"];
    NSURLRequest* request = [NSURLRequest requestWithURL:url];
    [webView loadRequest:request];

Where "index.html" relatively references images, CSS, javascript, etc.

@sdbrain's answer in Swift 3:

    let url = URL.init(fileURLWithPath: Bundle.main.path(forResource: "index", ofType: "html", inDirectory: "www")!)
    webView.loadRequest(NSURLRequest.init(url: url) as URLRequest)
