Question

I subclassed CCSprite to detect a touch to itself.

touchBegan fires upon touch, but log shows that the same sprite is handling touches all the time even though I am touching different sprites every time.
(It’s pointer address is same for all touch.)

Further log shows that it’s the last sprite I added to the world layer.

Why is the last sprite I added react to touch events all by itself?

I used CCSpriteBatchNode, would this be related to the problem?

Or is it because cocos2d just doesn’t perform hit-test to find the correct object to deliver the touch event to?

You need to check if the location of the touch is inside the bounds of your sprite.

Some weird pseudocode

function touchBegan(UITouch touch, etc)
    CGPoint pos = get location of touch;
    if (CGRectContainsPoint(sprite.boundingBox, pos)) //I think that is the method you need. It's something like that.
        NSLog(@"Sprite was touched!");
        return YES;
