How exactly can you inform Interface Builder that your NSView subclass supports a given binding?

For example, I created a class that had the following:

Code:
+ (void)initialize
{
    [self exposeBinding:@"string"];
}
- (void)setString: (NSString *)string
{
    _string = string;
}

- (NSString *)string
{
    return _string;
}

That should, I think, do everything in order to make the object both KVC compliant and respond to the binding. When I dragged the header to IB, though, I only get "hidden" for bindings for that view.

Has anyone ever used bindings for anything real?

I'm working on a program that uses them, but:

a) it's pretty small (~1500 lines)
b) I haven't worked out how to do what you're asking about
c) I think NSArrayController needs a delegate method "selectionDidChange"

I found the answer.

You need to make your view into an IB pallete to be able to do this. I forsee one huge pallete that I'll be able to grab views like crazy from. Maybe I'll write something for CDC on this.

GAH! I wish IB could read more into the code part of projects. Say, have it check -awakeFromNib, or +initialize or something for calls to exposeBinding:
