iphone - cocos2d中如何给Button添加Action

Question

我使用这段代码为我的 cocos2d 项目创建了我的 Button

CCMenuItem *starMenuItem = [CCMenuItemImage 
  itemFromNormalImage:@"ButtonStar.jpg" selectedImage:@"ButtonStarSel.jpg" 
  target:self selector:@selector(starButtonTapped:)];
starMenuItem.position = ccp(60, 60);
CCMenu *starMenu = [CCMenu menuWithItems:starMenuItem, nil];
starMenu.position = CGPointZero;
[self addChild:starMenu];

现在我需要将我的 sprite 跳跃 Action 链接到这个按钮。我该怎么做......？

你可以这样做，

CCLabelBMFont *startLabel = [CCLabelBMFont labelWithString:@"Start Game" fntFile:@"Arial.fnt"];
CCMenuItemLabel *startItem = [CCMenuItemLabel itemWithLabel:startLabel target:self selector:@selector(startGameTapped:)];
startItem.scale = 1; 

CCMenu *menu = [CCMenu menuWithItems:startItem,nil];
[menu alignItemsVerticallyWithPadding:20];
menu.position = ccp( winSize.width/2, winSize.height/2);
[self addChild:menu];
