cocos2d触摸分发的原理参考下面的一篇文章.

但是在cocos2d 2.0的版本中用法有点不一样.之前的addTargetedDelegate用法是:
[[CCTouchDispatcher sharedDispatcher] addTargetedDelegate:self priority:-1 swallowsTouches:YES];
现在是:
[[[CCDirector sharedDirector] touchDispatcher] addTargetedDelegate:self priority:-1 swallowsTouches:YES];
CCTouchDispatcher作为CCDirector中的一个@property存在,而不再是单例了.
