Hi everybody, I'm currently developing an app that allows the user to track where they have moved on a map. I'd like to create a CustomView, which is a subclass of NSImageView. The view should draw both the image of the map and NSBezierPaths that represent the track. Now my questions are: 1. How do I create a subclass of NSImageView? Specifically, how can I customize the '- (void)drawRectNSRect)dirtyRect' while still drawing the image set in InterfaceBuilder? 2. How can I add instances of NSBezierPath to the view, on top of the image of the map? Thanks for any input!
