Congratulations, it looks like you got the hard parts!
NSButtonCell inherits from NSActionCell and NSCell. (See 2nd line of the NSButtonCell documentation). Click the links. Now, try -[NSCell setState:], which will probably work, and -[NSActionCell setObjectValue:], which might work.

Hi, Jerry, Thanks for your advice. I tried [cell setState:NSOnState] & [cell setObjectValue:[NSNumber numberWithInt:1]], but still checkbox is in off state.
