   Is it possible?
   I have a menu with 10 items, each item calls a function (should call the same function) with a different string.

   so i end up having 10 different functions for example:

   CCMenuItemFont * m0 = [CCMenuItemFont itemFromString:@"0" target:self selector:@selector(inf0:)];
   CCMenuItemFont * m1 = [CCMenuItemFont itemFromString:@"1" target:self selector:@selector(inf1:)];
   
   -(void)inf1:(id)sender
   {
   [self callAFunc:@"blaaaaa"];
   }
   
   -(void)inf2:(id)sender
   {
   [self callAFunc:@"blaaaaa2"];
   }

   is there a way i could set that up so i can just do:
   

   CCMenuItemFont * m0 = [CCMenuItemFont itemFromString:@"0" target:self selector:@selector(inf:???)???];
   CCMenuItemFont * m1 = [CCMenuItemFont itemFromString:@"0" target:self selector:@selector(inf:???)???];
   
   -(void)inf:(id)sender data:(NSString *)data
   {
   [self callAFunc:@"data"];
   }

   thanks

   That's why you have that (id)sender in the selector, so you know which menu item sent message. Simply add tags to menu items and then decide what to do in selector:
   

   item1.tag = 1;
   item2.tag = 2; // etc...
   
   -(void)inf:(id)sender {
   CCMenuItem *item = (CCMenuItem *)sender;
   
   // now do what you want based on item.tag

   Great post. It hadn't occurred to me to pump sender full of data when using one of these callbacks.
