"scrollsToTop" equivalent for UIWebView?

Does UIWebView have an analogous property to UIScrollView's scrollsToTop? Can't seem to find one in the docs...

Would be nice to emulate Safari's behaviour in this respect (I notice that, for instance, the Facebook app manages).

Obviously this is possible to hack by placing a UIWebView within a UIScrollView and abusing scrollViewDidScrollToTop, but I'm hoping for something a bit cleaner.
