Notification when NSPopupButton changes its value in cocoa XCode5

Question

I want to know if is it a method different to

-(void)menu:(NSMenu *)menu willHighlightItem:(NSMenuItem *)item

and

-(void)menuDidClose:(NSMenu *)menu

to help me to know when NSPopupButton's selected value changes (for example by pressing a key name instead of selecting it from the NSMenu)

Answer 1

first create your IBAction:

- (IBAction)mySelector:(id)sender {
    NSLog(@"My NSPopupButton selected value is: %@", [(NSPopUpButton *) sender titleOfSelectedItem]);
}

and then assign your IBAction to your NSPopupButton

    [popupbutton setAction:@selector(mySelector:)];
    [popupbutton setTarget:self];
