Without extending UIButton you can add a unique TAG to the button, getting the tag from the source of the UIEvent.

IE:

-(void) buttonSetupMethod {
    for(each item) {
        UIButton * button = [[UIButton alloc] init];
        ... additional setup ...
        button.tag = SOME_UNIQUE_TAG_FOR_BUTTON;
        [button addTarget:self action:@selector(processaction:) forControlEvents:desiredEvents];
        ... retain button ...
     [button release];
    }
 }

 -(void) processAction:(id) source
 {
     UIButton * button = (UIButton *) source;
     int tag = button.tag;
     ... conditional logic on specific tag ...
 }
