NSPasteboard indeed does not implement a setDelegate: method.
The object you pass as <owner> in -declareTypes:owner: can act as the
pasteboard's delegate in the case of when you promise (but do not
actually provide) data when writing your data types to the pasteboard.
What are you trying to do? Seems to me that attempting to become a
"permanent" delegate of the general pasteboard in an awakeFromNib
method is a very weird thing to do.
Have you read this?:
file:///Developer/Documentation/DocSets/com.apple.ADC_Reference_Library.CoreReference.docset/Contents/Resources/Documents/documentation/Cocoa/Conceptual/CopyandPaste/Articles/pbImplementing.html
#//apple_ref/doc/uid/TP40004255-SW2
In particular the section on "Lazy Writing". This is about the only
time that the delegation pattern is used by NSPasteboard.

Hi,
I am trying to set my object as delegate of
NSPasteBoard. I am calling from awakeFromNib
NSPasteboard *pb = [NSPasteboard generalPasteboard];
[pb setDelegate:self];
However, on running, it raises exception. There is
also a warning at compile time that says NSPasteboard
may not respond to method setDelegate.
Please tell me how can i set my own class as delegate
of NSPasteboard.
Thanx
