The docs say you should not set owner: to something fleeting, that could disappear and thus when asked for the proper pboard type not be able to respond. I have an NSImageView subclass and I am trying to implement copy. Currently I just say [pboard declareTypes: [NSArray arrayWithObjects: NSTIFFPboardType, nil] owner: nil] then I immediately set the data: [pboard setData: [[self image] TIFFRepresentation] forType: NSTIFFPboardType]. However, I would like to provide several options, speficially I would like to send declareTypes [NSImage imageUnfilteredPasteboardTypes]. The problem is, I don't know what owner to set, let alone how to convert to all those different types. I was thinking of setting the owner to a Class that way it is independent of any object which may be released, but after the app quits then I'm still left with nothing correct? So my question is twofold: what is the best way to implement copy and how do I convert to all those different types.

Thanks in advance,
