MenuItem @Selector Help?

Hello,

I am a newbie at cocos2d and I am making a basic game to get the hang of how cocos2d works. I ran into a problem with the MenuItems. I need a way to know what menu item was pressed.

For Example:

CCMenuItem *a = [CCMenuItemFont itemFromString:@"A" target:self selector:@selector(check:)];
CCMenuItem *b = [CCMenuItemFont itemFromString:@"B" target:self selector:@selector(check:)];
CCMenuItem *c = [CCMenuItemFont itemFromString:@"C" target:self selector:@selector(check:)];

I need all the menu items to go through check: but I can't figure out a way to figure out what menu item was pressed. I tried working with the sender for check: but it didn't seen to tell me exactly what button was pressed.

If someone could give me some pointers or maybe a better way of doing this I would greatly appreciate it.

a.tag = 1;
b.tag = 2;
c.tag = 3;

.....

if ([sender tag] == 1)
{
    //a was pressed
}

This doesn't work for me. [sender tag] is always -1. No matter what button is pressed! It's always -1.

I can get the button by using getChildByTag but I can't go the other way.... If [sender tag] actually worked my life would be so much easier. If I can't get it to work I am going to need to create a function for each button that does nearly the same thing. When you have nearly 50 buttons, this is a pain in the a$$!!!!!

Are you certain your tags are set? Place a breakpoint in the target selector to verify.

You can also use the userData to store a pointer directly to whatever you're testing the tags for:

STParty *tempParty = ((CCMenuItemSprite *)sender).userData;

but note that you won't be getting around whatever issue is causing tag to be -1.

I'm able to access the MenuItem by

[self getChildByID:1001]

So the tag must be set properly, for instance if I change the visibility, the button disappears as expected.

[[self getChildByID:1001] setVisible:NO];

I was tagging the wrong part. I was tagging the menu and not the button in the menu. All is good now.
