前段时间项目中要微博授权登陆，使用的是web登陆方式。所以要在cocos2d-x中显示网页。所以就将UIWebView用进来了。
实现上讲也不是很难，你开打AppController.mm，你可以看到cocos2d-x的场景是被加载在一个EAGLView上面。所以我只需要取到EAGLView，在上面加一个UIView，UIView上面就可以放我的UIWebView。
实现：FMUIWebViewBridge.h

因为这些都是OC代码，所以文件后缀使用mm，为了和C++代码混编。代码很简答，应该看得懂，我就不解释了。
下面就是封装这个oc代码，
FMLayerWebView.h

OK ,这样就完成了。
调用方法：
| 1 2 3 4 5 | FMLayerWebView* web = FMLayerWebView::node(); web->setPosition(CCPointZero); addChild(web); |
