 1 //全部所有的触摸点一起触发
 2     auto listener = EventListenerTouchAllAtOnce::create();

 4     listener->onTouchesBegan = [](std::vector<Touch*> ts, Event *e){
 5         log("onTouchesBegan");
 6     };

 8     //获得触摸点的数量
 9     listener->onTouchesMoved = [](std::vector<Touch*> ts,Event *e){
10         log("touches moved,and touch count is %ld", ts.size());
11     };
