You can set a different tag value for each button (in IB), then in the
action method use -[sender tag] to get the value. Tags are just an
integer number that most controls support and their use is entirely
decided by the programmer - Cocoa doesn't use them.
Alternatively you can of course just have two different action
methods, one for each button - very often this will be the cleaner
solution.
