Iphone development

I'm still new to objective-c. I want to create an application on iphone where I take data from XML using NSXMLParser. so when i run the app it will read the XML and the data comes from that, but in between the appliaction starts, if the XML is refreshed, then how can my app know about it and get the refreash data? Please help me with this.

It looks like your application will benefit from the new Push Notifications API in OS 3.0.

There is no magic. Either your application has to poll, or you can keep the connection open and send a message from the server when data changes.



Apple push notification may or may not do this, but either way, the easiest way you're currently in is to poll your server.
