Show NSSegmentedControl menu when segment clicked, despite having set action

Question

I have an NSSegmentedControl on my UI with 4 buttons. The control is connected to a method that will call different methods depending on which segment is clicked:

Answer 1

Subclass NSSegmentedCell, override method below, and replace the cell class in IB. (Requires no private APIs).

- (SEL)action
{
    //this allows connected menu to popup instantly (because no action is returned for menu button)
    if ([self tagForSegment:[self selectedSegment]]==0) {
        return nil;
    } else {
        return [super action];
    }
}
