I need to implement an RSS reader on iOS which updates its feed every # minutes, even if the app is in the background. I don't mind using NSXMLParser to do the parsing of the data, I just need a good way to do the following in the background at scheduled intervals:
Download the feed's XML document
Parse the document
Let the user know of any updates
I know how to do all of these things when the app is running, I just need to know how to make sure they get done even if the app is in the background.
