Earlier today I came across a tweet that mentioned that Automator can make Services in Snow Leopard. So, I jumped right on it and make 2 very convenient services for developers, which make use of class-dump. Feel free to download them and try them out!
To install them, just extract the .zip file and move the 2 service files into ~/Library/Services.
To use them, navigate to the Application or Framework that you want to class-dump, right-click (or control-click) to bring up their context menu, and choose one of the two services. It will ask for a destination folder to save the folder containing the headers (or just a single header file, if that’s the service you clicked at the moment) and then you’ll see the headers saved right there.
Neat, eh?
(By the way, you can open the 2 service files with Automator to modify them to your likings.)
Note: you will need to have already installed class-dump (free download), by Steve Nygard, before this will work.
