You always get the DidEndEditing whether any changes happened or not.
You can either compare the value at that time with the original value
to see if it changed, or you can also catch DidChange and make a note
of it.
The first requires you know what the original value is, but usually the
text field is reflecting a model value somewhere so often this is easy
enough. The second requires a little book-keeping, and it also will
have false positives if I edit the field but wind up editing it back to
the same value it had originally.

Subject: Detecting A Changed Cell When Editing Ends
I want to know when a text field cell ends editing AND has been
changed.
controlTextDidChange: fires off a notification with every keystroke.
I only
want to know about the change when editing ends.
controlTextDidEndEditing: notifies me when editing ends, whether the
cell
has changed or not. I want to know whether the cell has changed.
Can someone point me in the right direction?
Jonathan
