Cocos2d-x中ImageView的使用

概述 Size size = Director::getInstance()->getVisibleSize();  ImageView* imageView = ImageView::create("ccicon.png");  imageView->setPosition(Vec2(size.width /2,size.height /2));  imageView->ignoreConten 

Size size = Director::getInstance()->getVisibleSize();

imageVIEw->setScale9Enabled(true);
imageVIEw->setContentSize(Size(100,100));
imageVIEw->setCAPInsets(Rect(20,20,20));//设置伸缩后的内框大小
imageVIEw->settouchEnabled(true);
imageVIEw->addtouchEventListener([=](Ref* sender,cocos2d::ui::Widget::touchEventType type){
