Brand new to Cocoa and I'm trying to figure out how to copy an NSAttributedString to the pasteboard. I've looked in the docs and not sure if I'm supposed to use a NSPasteboardItem or not.

Here's what I have to copy a regular NSString:

NSPasteboard *pb = [NSPasteboard generalPasteboard];
NSArray *types = [NSArray arrayWithObjects:NSStringPboardType, nil];
[pb declareTypes:types owner:self];

[pb setString:@"asdfasdf" forType:NSStringPboardType];

How do I set a NSAttributedString?

Thanks
