Scroll to top of UITableView by tapping status bar

You get this for free, but you should check that the scrollsToTop attribute of your UITableView is YES.

When this does NOT work is when you have a UIScrollView (or descendant class like UITextView) object embedded inside another UIScrollView class (like UITableView). In this case, set scrollsToTop on the embedded UIScrollView class to NO. Then the tap-the-status-bar behavior will work.
