Calling [super scrollViewDidScroll]; on subclass of UIWebView crashes
<p>I'm not sure how this works.  I was following this post:  <a href="http://stackoverflow.com/questions/8857655/check-if-uiwebview-scrolls-to-the-bottom">check if UIWebView scrolls to the bottom</a></p>

<p>I want to know when the scrollViewScrolls to do some custom things.  I subclasses UIWebView.  All I did was this so far:</p>

<pre><code>- (void)scrollViewDidScroll:(UIScrollView *)scrollView {
    [super scrollViewDidScroll:scrollView];
    NSLog(@"%s", __FUNCTION__);
}
</code></pre>

<p>It crashes on the <code>[super scrollViewDidScroll:scrollView]</code> method.  When I delete that line, it works fine.  I don't want to take away the superclass' implementation of this method.  I just wanted to add some custom functionality to it (place a toolbar above the webview like the Facebook app).  Is there a reason why this is crashing?  Thanks.</p>
