objective-c - Which NSTextView is the First Responder?

Question

I'm working on a Cocoa programming exercise, and I need to be able to determine which of two NSTextView objects is currently being edited. I think it's something to do with finding the first responder and checking to see if it's equal to one text field or another, but I can't quite get it to work. Any help would be appreciated.
