在UIPanel(tag = 2017)上放置一个UIButton(tag = 2005)。
一个手指在UIPanel上触摸并移动(手指没有抬起)，此时另一个手指点击UIButton(手指按下未抬起)，UIPanel却收到了TOUCH_EVENT_ENDED消息。
然后UIPanel上的手指再移动，UIPanel就收不到TOUCH_EVENT_MOVED了。
怎样才能让UIButton的点击操作，不影响UIPanel呢？
下面是源码
panelJoyStick = (UIPanel*)uiJoyStickLayer->getWidgetByName(“Panel_JoyStick”);
panelJoyStick->addTouchEventListener(this, toucheventselector(FightScene::onPanelTouch));
btnAttack = (UIButton*)uiJoyStickLayer->getWidgetByName(“Button_Attack”);
btnAttack->addTouchEventListener(this, toucheventselector(FightScene::onButtonTouch));
