 ImageView * imageView = ImageView::create("cocosui/ccicon.png");//新建图片

 imageView->setScale9Enabled(true); //是否启用九宫格显示模式

 imageViewChild->setSizeType(Widget::SizeType::PERCENT);//设置大小类型
 imageViewChild->setSizePercent(Vec2::ANCHOR_MIDDLE);//设置大小比例
 imageViewChild->setPositionType(Widget::PositionType::PERCENT);//设置位置类型
 imageViewChild->setPositionPercent(Vec2::ANCHOR_MIDDLE);//设置位置比例
 imageViewChild->setPosition(Vec2(widgetSize.width / 2.0f,
                                     widgetSize.height / 2.0f));//设置位置
 imageView->addTouchEventListener([=](Ref * sender, Widget::TouchEventType type){

 if (type == Widget::TouchEventType::ENDED){

 float width = CCRANDOM_0_1() * 200 + 50;

 float height = CCRANDOM_0_1() * 80 + 30;

 imageVIew->setContentSize(Size(width, height));

 imageViewChild->setPositionPercent(Vec2(CCRANDOM_0_1(), CCRANDOM_0_1());

 }

 });

 imageVIew->setColor(Color3B(159, 168, 187); //设置图片颜色

 imageVIew->setContentSize(Size(250, 115)); //设置图片大小

 imageView->setFilppedX(true); //在X轴上翻转

 imageView->setScale(0.5); //设置图片放大系数，当前系数+1

 imageView->ignoreContentAdaptWithSize(false); //如果设置为true，忽略内容适应，使用系统默认的渲染大小，与实际的图片资源大小无关
