How to refresh a UIWebView by a “pull down and release” gesture?

Question

I know that this is possible in the Tweetie for iPhone or the xkcd iPhone app, but they are using a table. Any idea if this can be done for a simple UIWebView a

To retrieve scroll events on UIWebView I personnaly use this code to get the scrollview that is inside the UIWebView :

- (void) addScrollViewListener
{
    UIScrollView* currentScrollView;
    for (UIView* subView in self.myWebView.subviews) {
         if ([subView isKindOfClass:[UIScrollView class]]) {
            currentScrollView = (UIScrollView*)subView;
            currentScrollView.delegate = self;
        }
    }
}

It's working. You can also use it to call [(UIScrollView*)subView setContentOffset:offSet animated:YES]; The only problem may be not to pass Apple code checking. I don't know yet since I'm still in coding phase.

Anyone tried that yet ?
