If it's a simple form, you can do this:

html cancelButtonWithAction: [self answer]

The modifications made at the same time as hitting Cancel will be 
ignored, although any modifications from previous requests (if they hit 
Save, stay on the same form, and then hit Cancel), would still come 
through.
