IPhone Web Service communication

We need to write an iPhone application.

The application would need to consume an web service for storing user information, user session. etc.

Also one feature expected is, we should able to ping any user through iPhone application [iPhone would call web service and pass on data however bot sure how the webservice would pass that text to respective iPhone user].

I have searched on net for most feasible options on net and came accross some options like,

  • Polling to web service.
  • WCF restful service for iPhone communication.
  • found some ready made servers for push to communication.
  • Can you please suggest best suitable and cost effective solution.

    Thanks in advance.


    You should read about the Apple Push Notification Service, which is designed exactly for the situation you describe. Your app can't poll a web service if it's not running, or if it's suspended. Push notifications let your server send a message through Apple to a device. If your app isn't running, the user will get an alert from which they can start your app. If the app is running, the notification is delivered transparently to the app.
