Button* Btn1 = (Button*)rootNode->getChildByName(“Button_1_2_6_10”);
Btn1->addTouchEventListener(this, toucheventselector(HelloWorld::onClick)) －－－－－－－－－－－Thread1:EXC_BAN_ACCEDD(CODE=1,ADDRESS=0*498
void HelloWorld::onClick(Ref*, TouchEventType type){
switch (type) {
case TouchEventType::TOUCH_EVENT_BEGAN:
break;
case TouchEventType::TOUCH_EVENT_MOVED:
break;
case TouchEventType::TOUCH_EVENT_ENDED:
if(Btn2->isVisible()){
Btn2->setVisible(false);
}
else{
Btn2->setVisible(true);
}
break;
case TouchEventType::TOUCH_EVENT_CANCELED:
break;
}
}
运行的时候会报出 EXC_BAN_ACCEDD(CODE=1,ADDRESS=0*498)的错误，请问这个是什么问题啊
