Build Your Own IPhone RSS Reader in 15 Minutes With Flash Builder

private function Changeit(event:IndexChangeEvent):void
{
var selIndices:Vector.<int> = event.currentTarget.selectedIndices;
var selItems:Vector.<Object> = event.currentTarget.selectedItems;
var numItems:Number = selIndices.length;
getDataResult2.token = descs.getData("description");
var importer:ITextImporter = TextConverter.getImporter(TextConverter.TEXT_FIELD_HTML_FORMAT);
ret.textFlow=importer.importToFlow(getDataResult2.lastResult[list.selectedIndex]);
}

The first three codeline reverses index numbers. The latest codes are for importing the content from the blog. Normally if you use TextFlow on his own, it will suspect it's a plain content receiving the feed. So we need to add "Html Format converter" to view html markup tags. According to the selectedindex we will bind content information of the feed. Why do we do this? Because when it adds new items in the list the first index is 11 (that's my blog post count). So to apply the the selectedindex method we need to first reverse the list control.

Your mxml file should look like this; check it before running RSSReader.

Runnning it:

Not as good as one in the apps Store but you can think of this application as a starter kit. I hope that its useful for anyone. If you have comments or problems, i'm curiously waiting for it. How many minutes did it take? Share your experience!
