UIWebview Html5 with inline SVG

I am trying to draw a basic circle with SVG inside of an Html 5 file and then load that inside of a UIWebview. However when I compile and run nothing appears on screen (testing on iPad).

Am I not using the correct code or is SVG with Html 5 not supported in UIWebview?

Here is the code for the UIWebview:

- (void)viewDidLoad 
{
    [super viewDidLoad];

    NSString*  path    = [[NSBundle mainBundle] pathForResource:@"SVG" ofType:@"html"];
    NSString*  content = [NSString stringWithContentsOfFile:path encoding:NSUTF8StringEncoding error:nil];

    webView = [UIWebView new];
    webView.frame = CGRectMake(0, 0, 1024, 768);
    webView.dataDetectorTypes = UIDataDetectorTypeAll;
    webView.userInteractionEnabled = YES;
    [webView loadHTMLString:content baseURL:[[NSBundle mainBundle] bundleURL]];

    [self.view addSubview:webView];
    [webView release];
}

Here is the code inside the SVG.html file that is called in the resources folder:

<!DOCTYPE html>
<head>
<title>SVG</title>
<meta charset="utf-8" />
</head>
<body>
<svg id="svgelem" height="200" xmlns="http://www.w3.org/2000/svg">
    <circle id="redcircle" cx="50" cy="50" r="50" fill="red" />
</svg>
</body>
</html>

I have been reading through many related posts but I have not been able to puzzle out the answer.

Any help is appreciated. Thanks.

That's because Safari (or what's inside UIWebView) has problems with embedded SVG elements. I heard that Apple is going to fix it, anyway...
Try this:

svg.html :

<html xmlns="http://www.w3.org/1999/xhtml">
  <head>
    <title>SVG</title>
  </head>

  <body>
    <object data="circle.svg" width="250" height="250"
    type="image/svg+xml" /> 
  </body>
</html>

circle.svg :

<svg xmlns="http://www.w3.org/2000/svg">
<circle r="50"/>
</svg>
