I am brainstorming notification framework for an iOS app for non-profit orgs. They should be able to login to a web site, enter their notifications and due dates. My iOS app would be able to invoke a web service call to this website, and check for any notifications, and display the iOS nofitication based on this cloud service. Do I need to get some one to build this web service from scratch? I can take care of iOS notifications but I don’t know how to take care of cloud service that would take care of users notification entries. Are there 3rd party services out there out there that provide this kind of notification web services that interact with iOS app notification framework?
