首先下载flex-iframe.swc,并添加到libs中

下面直接上代码
复制代码 代码如下:
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"

xmlns:code="http://code.google.com/p/flex-iframe/"
minWidth="955" minHeight="600"
creationComplete="application1_creationCompleteHandler(event)">
<fx:script>
<![CDATA[
import mx.events.FlexEvent;
protected function application1_creationCompleteHandler(event:FlexEvent):void
{
this.myiframe.source = "http://m.weather.com.cn/m/pn11/weather.htm";
}
]]>
</fx:script>
<fx:Declarations>
<!-- 将非可视元素(例如服务、值对象)放在此处 -->
</fx:Declarations>
<code:IFrame id="myiframe" width="100%" height="100%"/>
</s:Application>
