菜单的创建与使用,代码如下:

@implementation HelloWorldLayer

@synthesize bird;


// Helper class method that creates a Scene with the HelloWorldLayer as the only child.

+(CCScene *) scene

{

// 'scene' is an autorelease object.

CCScene *scene = [CCScene node];

// 'layer' is an autorelease object.

HelloWorldLayer *layer = [HelloWorldLayer node];

// add layer as a child to scene

[scene addChild: layer];

// return the scene

return scene;

}

{

    NSLog(@"load addition fired!");

}


- (void) loadSubtraction: (id) item

{

    NSLog(@"load subtraction fired!");

}


// on "init" you need to initialize your instance

-(id) init

{

// always call "super" init

// Apple recommends to re-assign "self" with the "super's" return value

if( (self=[super init]) ) {

        

        isTouchEnabled_ = YES;

        /*

        CCMenuItemImage *menuItem1 = [CCMenuItemImage itemWithNormalImage:@"" selectedImage:@"" target:self selector:@selector(loadAddition:)];

}

return self;

}


// on "dealloc" you need to release all your retained objects

- (void) dealloc

{

// in case you have something to dealloc, do it in this method

// in this particular example nothing needs to be released.

// cocos2d will automatically release all the children (Label)

// don't forget to call "super dealloc"

}
