if (ccCArrayContainsValue(m_pHandlersToRemove, pDelegate))

ccCArrayRemoveValue(m_pHandlersToRemove, pDelegate);

}
// CCTouchHandler CCTouchDispatcher::findHandler(CCTouchDelegate *pDelegate)并不会检索m_pHandlersToAdd，所以不知道这是设计上的遗漏，还是有意为之。
m_pHandlersToAdd->addObject(pHandler);
m_bToAdd = true;
}
}
当点击个菜单按钮时，m_bLock == true, 此时如果新建个其他可触摸对象A，并启用A的触摸，那么此时通过findHandler是检索不到A的，那么就无法对A进行一些操作。我觉得这不是很方便。
