macOS How to subclass NSImageView and add NSBezierPaths to it?

[ranguvar]

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!

You might want to consider using Core Animation's layers for this.
