在含有精灵的layer中，你需要输入：

self.isTouchEnabled = YES;

然后，你可以使用在UIView中的相同event，但是它们被调用的方法不同：

- (void)ccTouchesBegan:(NSSet*)touches withEvent:(UIEvent*)event
{
   UITouch* touch = [touches anyObject];
  //in your touchesEnded event, you would want to see if you touched
  //down and then up inside the same place, and do your logic there.
}

想要实现这种效果，可以给精灵设置定界框（bounding box），在下述代码中，我将所有精灵都置于NSMutableArray中，并检查它们是否处于定界框内，同时要保证已经初始化触摸操作：

- (BOOL)ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event 
{
  CGPoint location = [self convertTouchToNodeSpace: touch];

  for (CCSprite *station in _objectList)
  {
    if (CGRectContainsPoint(station.boundingBox, location))
    {
      DLog(@"Found sprite");
      return YES;
    }
  }

  return NO;
}

根据Jonas的回答，我又进行了进一步的完善：

- (void)ccTouchesBegan:(NSSet*)touches withEvent:(UIEvent*)event
{
   UITouch* touch = [touches anyObject];
   CGPoint location = [[[Director sharedDirector] convertCoordinate: touch.location];
   CGRect particularSpriteRect = CGMakeRect(particularSprite.position.x, particularSprite.position.y, particularSprite.contentSize.width, particularSprite.contentSize.height);
   if(CGRectContainsPoint(particularSpriteRect, location)) {
     // particularSprite touched
     return kEventHandled;
   }
}

你可能需要调整x/y的位置，保证精灵的“中心位置”。

David的代码在Cocos 0.7.3和2.2.1上，会出现错误信息，所以我用CGRectMake替代CGMakeRect，用[touch locationInView:touch.view]纠正了[touch location]的错误：

- (BOOL)ccTouchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {
    UITouch * touch = [touches anyObject];

    CGPoint location = [[Director sharedDirector] convertCoordinate: [touch locationInView:touch.view]];
    CGRect myRect = CGRectMake(sprite.position.x, sprite.position.y, sprite.contentSize.width, sprite.contentSize.height);


    if(CGRectContainsPoint(myRect, location)) {
        // particularSprite touched
        return kEventHandled;
    }
}
