Good open source Mac OSX App for code study? [closed]

Question

I'm rewriting my Mac OSX App (which is full of spaghetti code), but before I do so, I'd like to take some time and study an existing Mac OSX App.

Is there something good available on github.com or elsewhere where I can learn good coding conventions?

Specifically I'm looking for Mac app that makes use for CoreData, NSOutlineView, Bindings, etc.

Thanks

Some places to start with:

• Sample Code from the Apple Developer Website
• Looking up the source code from an open-source program. Here's a list of open source programs from opensourcemac.org and another from Mac.AppStorm. Adium, Cyberduck, Vienna, Transmission are some solid apps I've used (though, not sure they make use of all of the features you've mentioned).
