问题
Many iOS apps have a "scroll up to refresh" feature, such as the Twitter app. If you scroll up beyond the beginning of the page or table, you'll get a message explaining how to use the feature.
That controller is not from Apple but many apps seem to use it. I was told it was released for public use by a programmer, but I can't find it after a long google session.
I'd be grateful if anyone can direct me to it! Thanks!

Also it was in Facebook's three20 library I guess.
