Snippet: Finding the Current First Responder

In iOS there is no simple call to retrieve the current first responder (without resorting to private APIs). A google search turns up lots of methods that involving walking the view hierarchy, but I really like this simple, efficient method by Jakob Egger posted as an answer to this question on stack overflow.

I don’t normally repost code from stack overflow, but the google incantations necessary to find this are non-obvious.
