   Hi there,
   forgive me for posting such a simple question but had a look around this forum and the google archived one and wasn't able to find a consistent solution.
   I'm using 0.7.3 and I'd like to have multiple menuitems share the same callback, but then I can't figure out which menuitem was pressed.
   Any ideas?
   Thanks!

   This worked putting a tag in the MenuItem, but this was for 0.6? release.

   Unfortunatelly the 0.7x release has not this, don't know about 0.8

   compare the sender argument from the callback to your menu item instances.

   Yeah I read about the tag method but doesn't work in 0.7
   I would prefer not to upgrade to 0.8 just because 0.7 works fine for my needs and I'm trying to get the game wrapped up and submitted soon.

   Thanks Joao.
   I'm doing this

   for (id item in mainMenu.children )
       if(sender==item)
           NSLog(@"found");

   But then how would I check what button it is?
   I have the instance of the MenuItemImage, can I check what index it is? Or something else?
   This sounds like a stupid question.
   Thanks :)

   Usually I keep a weak reference to the MenuItem in my scene (don't retain it), doing something like this:

   @interface MyScene : Scene
   {
   MenuItem* itemA;
   }

   @end

   @implementation MyScene

   -(id) init
   {
   ...
   itemA = [MenuItemWhatever initBlaBla];
   Menu* menu = [Menu menuWithItems:itemA, nil]; //or something like this.
   [self addChild:menu];
   }

   @end

   Then compare like this:

   if(sender==itemA)
   NSLog(@"found");

   Ah I see.
   I suppose it can become a bit fidgety if you have lots of menuitems like I'm planning to have (about 12, not that many really...).
   Still, it works and that's what matters the most :)
   Thanks for your help!

   What I did in 0.7.3 was expose selectedItem in Menu class. It's private but easy to change. I populate my Menus from an array, so I just match the array index with the selectedItem index. However when you move to 0.8 selectedItem changes from an int to a MenuItem. I had to change how I handled these selections.

   Wouldn't be better sending to riq an enhacement request with the proper code?

    He explained that it was not in the spirit of cocos2d to expose it, which I have no problem with. 0.8 returns the actual MenuItem anyway.
