调用：

        if(cc.sys.os == cc.sys.OS_IOS || cc.sys.os == cc.sys.OS_OSX){        var ret = jsb.reflection.callStaticMethod("shangCheng", "CreatShangChengWebViewWithURL:", "http://www.baidu.com");        if (ret) {        cc.log("创建成功！");        }        if (!ret) {        cc.log("创建失败");        }        }

上面有两个OC文件，放在Xcode工程iOS文件夹下即可。在Cocos2d-js工程里面调用上面的javascript代码段即可。
