PageView翻页视图，感觉应该用的很多，这个用起来不难我这边就简单介绍一下，本来想再讲一个RadioButtonGroup单选按钮组，可是死活显示不了不知道为什么，等以后再讲吧，反正用到的也不多。这篇也算是UI控件近阶段一个结束篇，可能以后我会接着介绍其他UI控件。

--------------------------------------------------------PageView

void HelloWorld::addPageView(){auto gb_sprite = Sprite::create("button/background.png");Size size_gb = gb_sprite->getContentSize();gb_sprite->setAnchorPoint(Vec2(0.5, 0));gb_sprite->setPosition(Vec2(480, 100));this->addChild(gb_sprite, 1);auto pageview = PageView::create();    //创建一个翻页视图pageview->setDirection(PageView::Direction::HORIZONTAL);    //设置方向，只有水平和竖直const char* image[] = { "button/Button01.png","button/Button01Disabled.png","button/Button01Pressed.png","button/Button02.png","button/Button02Disabled.png","button/Button02Pressed.png" };for (int i = 0; i < 6; i++){auto imageview = ImageView::create(image[i]);imageview->setContentSize(Size(240, 240));imageview->setScale9Enabled(true);Layout *layout = Layout::create();        //先创建一个layout，把ImageView放到layout上layout->setContentSize(Size(480,480));layout->addChild(imageview);imageview->setPosition(layout->getContentSize() / 2);pageview->setContentSize(Size(480, 480));pageview->insertPage(layout, i);             //ImageView不能直接加到PageView，其他没有试，其实把每页都做成一个layout也挺好的layout->setPosition(pageview->getContentSize() / 2);}pageview->setAnchorPoint(Vec2(0.5, 0.5));pageview->setPosition(Vec2(480, 320));pageview->addEventListener(CC_CALLBACK_2(HelloWorld::PageViewEvent, this));  //监听翻页事件this->addChild(pageview,1);}void HelloWorld::PageViewEvent(Ref* pSender, PageView::EventType type){PageView* pageview = (PageView*)pSender;switch (type){case cocos2d::ui::PageView::EventType::TURNING: log("PageView::EventType::TURNING pageview->getCurPageIndex() = %d", pageview->getCurPageIndex());break;default:break;}}

你滑动框图就可以翻页，并且翻页时候会调用翻页回调函数，静态图看不出效果我就不给效果图了

后面使用UI做个游戏，练练手...
