Redrawing an NSView

Tags:

Sorry if this has been asked before or it's a really dumb question, but I can't figure it out. I have an NSView in my interface, and I have created a subclass of NSView in Xcode. Then using the identity inspector, I set my NSView's class to be the newly created NSView subclass. The view draws fine, but now I need to redraw it to change a string inside the view. I'm pretty sure this has to do with setNeedsDisplay, but what do I send the message to? I don't have a particular instance of my view in the code, since it's in Interface Builder, so what do I do? Again, sorry if this is dumb. I haven't done much with NSView yet. Ask for more info if you need it. Thanks!
