You can inject html markup such as My Button into the content of your UIWebview using stringByEvaluatingJavaScriptFromString method.

To capture the click event and prevent it from reloading content of your webview use this delegate:

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
{
    if(navigationType==UIWebViewNavigationTypeLinkClicked && [[request.URL absoluteString] isEqualToString: @"yourTag01"])
    {
        //your custom action code goes here
        return NO;
    }
    return YES;
}
