How do I make UIWebView scroll to the top?

Question

Is there a way to make a UIWebView scroll to the top when I touch say a UISearchView within the same viewController (without using Javascript).

Something like this:

- (void)searchBarTextDidBeginEditing:(UISearchBar *)searchBar
{
      [myWebView scrollToTop];    //pseudocode 

}

In other words, what happens when I touch the top bar can also happen programmatically.

Answer 1

CGPoint top = CGPointMake(0, 0); // can also use CGPointZero here
[myWebView.scrollView setContentOffset:top animated:YES];

(Note that if you have set myWebView.scrollView.contentInset.top you will want to take that into account instead of just scrolling to CGPointZero.)

Answer 2

Here's a really ugly, terrible way to do this. I'm answering this to show you what never to do.

for (UIView *subview in webView.subviews)
{
    if ([subview isKindOfClass:[UIScrollView class]])
        [(UIScrollView*)subview setContentOffset:CGPointZero animated:YES];
}
