Background process to alert the user in iphone?

I am developing a iphone uiwebview based application to load an web application url by getting the user credential from a login screen,as i have username and password which are required to communicate with the server on the other end with web services,i want to make an alert with some data to the user once after he logged into application.

But can i able to give that alert even he closes my application if then please suggest m开发者_运维知识库e how to do so?

I mean can i run any background service that can allow me to communicate some server with webservice calls and alert the user?

Thanks in advance......

If I understand your question right, you need to implement a push notification service for your app. Did you have a look at Apples documentation on local and push notifications? http://developer.apple.com/iphone/library/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/Introduction/Introduction.html

Or have a look at thee WWDC Video about it on iTunes.
