Is there a way to get constants using the Objective-C interface? For example, NSToolbarPrintItemIdentifier is a NSString constant -- I don't see a way to get it into Lisp other than trying to hunt it down and copy the value from a header file.

John, if you do not mind I would like to add to your question. I have been trying to work the low-level example in the Apple coredata documentation and found myself blocked by the same issue, only to realize that I had to hunt the header files like you did. In addition, I have not been able to figured out how one adds a boolean value like in [dateAttribute setOptional:NO]; (objc:invoke date-attribute "setOptional:" 0) ? What are the values or calls to replace NO or YES?

As another follow up to John's question. I am trying to develop some code using QTKit but it seems like the values of the constants are hidden some where. For example, QTMovieDurationAttribute is defined in the header file as QTKIT_EXTERN NSString *QTMovieDurationAttribute Has anyone been successful in using QTKit?
