Size size = Director::getInstance()->getVisibleSize();
cocos2d::ui::ScrollView* sView = cocos2d::ui::ScrollView::create();
sView->setContentSize(Size(500,400));
//sView->setDirection(ui::ScrollView::Direction::HORIZONTAL);//可以设置横向滑动
sView->setBackGroundImage("ccicon.png");
sView->setAnchorPoint(Point(0.5f,0.5f));
sView->setPosition(Vec2(size.width /2,size.height/2));
sView->setRotation(45);//45度滑动

Button* button = Button::create("animationbuttonnormal.png", "animationbuttonpressed.png");
