Cocoa articles on Cocoa bindings and MyGraphView
The two articles I wrote for the, unfortunately, no longer existing MacFreak Magazine are now available for download from this website. The first article is an introduction to Cocoa Bindings. The second article explains how to write a subclass of NSView, MyGraphView. In this case, it is a small graphing/plotting view. Source code is still available too on the sample code page.
These articles are in Dutch.
