Found this in my garden today in Sydney, Australia (specifically Lane Cove). Can you tell me what it is?





Question: How can I get a UIWebView's UIScrollView delegate methods called from within a standard UIViewController?
Answer: 
Have you checked there is only one UIScrollView subclass in the subviews? Bung in a log in your loop to see. If there is more than one, then you'll only pick up the last one using your code.
If there is just one UIScrollView subclass, you could try saving a reference to its delegate and then in your own delegate methods passing messages on after you have done your business.


So, in your loop, something like

originalDelegate = s.delegate


And then for the delegate methods, something like:

- (void) scrollViewDidScroll: (UIScrollView*) scrollView;
{
     // do your stuff

     [originalDelegate scrollViewDidScroll: scrollView];
}


You might need to check whether originalDelegate responds to the selector before calling it, i.e. if ([originalDelegate respondsToSelector: @selector(scrollViewDidScroll:)) etc. If it were me, I'd start by implementing all twelve delegate methods defined in the UIScrollView delegate protocol.

Not tested this, so will be interested to know if it can be made to work. Do note, the docs explicitly say that UIWebView "should not be subclassed"
