    //CCMenu
    CCMenu *starMenu = [CCMenu menuWithItems:starMenuItem,starMenuItem2,starMenuItem3,starMenuItem4,starMenuItem5,starMenuItem6,starMenuItem7,nil];

    starMenu.position = ccp(winSize.width/2  , 25);
    [starMenu alignItemsHorizontally];
    [self addChild:starMenu];


-(void)starButtonTapped:(id)sender {
if (/*press starMenuItem4*/) {
   /*do this*/
}else if(/*press starMenuItem4*/){
 /* do another thing*/
}
}

我的所有menuItem都有一个名为“”starButtonTapped的公共选择器：“。但是，我如何区分我在选择器中点击了哪个按钮，以便我可以为每个按钮执行不同的操作？我尝试不要选择多个选项他们很乱。谢谢你的帮助。

您可以使用代码：starMenuItem.tag = 1;

-(void)starButtonTapped:(CCMenuItem*)sender {

  switch(sender.tag) {
   case 1: // starMenuItem pressed 
     /*do this*/
     break;
   case 2: // starMenuItem2 pressed 
     /*do that*/
     break;
  }
}
