I have a controller object with an outlet pointing to a NSView

typed to these specific classes, I have to #import each header so the
compiler can see what it needs to compile, but I'm getting some kind
of circular problem where the NSView's source imports the controller's
header, which in turn imports the view's header, and round and round
it goes. So I get a compile error. In the NSView's source code,
changing this declaration:
Use the @class directive:
<

LanguageOverview/chapter_4_section_5.html>
IBOutlet id *theView;
Note that this is not what you intend. This is a pointer to an
object, not an object -- think of it as an untyped
NSObject **theView. You would just use,
IBOutlet id theView;
except that Interface Builder treats all id's as outlets anyway, so
you would only need:
id theView;
