Get Last Update Date of Forum For Use In iOS App
I have an iOS app that I would like to interface with an Vanilla forum in a very simple way. I would like the iOS app to request the last update date of the forum. That way I could indicate to the iOS app user the forum has been updated since their last visit.
I am guessing the way to go would be using Vanilla's REST services, but I am unsure of how to request the last update date, or if its even possible using REST.
I am studying information at this link: http://vanillaforums.org/discussion/17525/vanilla-rest-services and also searching through the PHP code to find something that might help.
Is there an easier way to do request the last update date of a Vanilla forum for use in an iOS app? If so, what is that easier way?
