I have a nib file containing an NSObjectController. The NSObjectController's content is set to the File's Owner proxy object, and this creates a retain cycle. (The file's owner never gets deallocated because the object controller retains it, and the object controller never gets deallocated because the file's owner retains it as an IBOutlet.)This is obviously a bad thing to do, but I always thought that it was good design for views and controls to be bound to an NSObjectController rather than the file's owner directly, since NSObjectController then takes care of all the NSEditor protocol stuff, you get auto-completion for model key names in Interface Builder, etc. Is there a better method than what I'm doing?
I wouldn't set the content to file's owner. I think you should set the content to an object that's contained by the file's owner, i.e. make the file's owner a controller object that owns the NSObjectController and has a reference/owns the content object.
