Hi everyone, I have a question that might seems a little silly. I
have a PDFDocument subclass which can perform page impositions. I
would also like to be able to undo the impositions. In the methods I
have this when I make the change to the PDF:
[[undoManager prepareWithInvocationTarget:self] initWithData:[self
dataRepresentation]];
[self initWithData:(NSData *)newPDFData];
When I call -undo: later, it works, but I can't get it to -redo:
Is what I'm trying to do even possible this way ? Is there a better
way?
Thanks for any pointers and/or suggestions!!
Kevin
