问题
Since the Finder in Snow Leopard has been rewritten to use Cocoa instead of Carbon, I'd like to know if there's a new API to write Finder plugins. The old way involved writing a CFPlugin but this doesn't seem to work anymore.
回答1:
If by plug-in you mean contextual menu, you can do this via the services API.
回答2:
I believe they prefer that you write Services instead of Finder plugins now.
