We're currently developing an html5 based iOS app using ExpressionEngine as the data source. So far it's working and looking great. However, we're unsure as to how approach the member side of things: we want to allow users to log in as they do on the main website. This appears to be somewhat of a challenge and we're wondering if anyone has come across a solution?
We're also using Zoo Visitor, but I don't think that's so relevant? It's the member authentication side of things we don't know how to tackle.
Any help would be much appreciated.
