A few minutes ago I updated the projects page. I added a subcategory Little Helpers in which I will publish some code snippets for different purposes.
The first one is an Objective-C class for accessing the keychain service in Mac OS X: STNKeychainAccess.
In the downloadable zip-file you can find a Xcode project with a small cocoa application which shows how this class can be used in your application.
Have fun!

I also did some work towards an ObjC wrapper for Keychain, before noticing a pretty susbtantial project already exists:
