Remove NSWindow content view

I set the content view for the following window and now i want to remove that content view and set it to something else. I tried just setting the content view to another view and that did not work, how can i just remove it? thanks! 

    controlFilterBox = [[MoveFilter alloc] initWithFrame:helpWindow.frame];
    [helpWindow setContentView:controlFilterBox];
    [controlFilterBox release];

You can't remove the contentView (i.e. set it to nil). The window requires a view. You probably can get what you're trying to do by calling [controlFilterBox setNeedsDisplay:YES], but I typically recommend that rather than messing with contentView itself, you make the views you want to swap to be subviews of contentView. Then you can just swap them around as normal views with removeFromSuperview and addSubview:. It's just often easier than dealing with a special view like contentView.
