Sending a message to a class

[jackosx]

I have a subclass of CCNode, and I want to have several instances of it, so my layer would send a message to it telling it which sprite to use. in my layer with the game I am using

		CCSprite *babybird = [CCSprite spriteWithFile:@"BabyBird.png"];
		BirdNode *bird1 = [BirdNode alloc];
		[self addChild:bird1];
		[bird1 setupWithBirdType:babybird];

and in my subclass of CCNode I have the method

-(void)setupWithBirdType:(CCNode *)type
{			NSLog(@"working");
	[self  addChild:type];
}

The setupWithBirdType method isn't being called, can anybody explain to me why?

You didin't init the BirdNode,, try that first.

BirdNode *bird1 = [[BirdNode alloc]init];

or 

BirdNode *bird1 = [BirdNode node];
