I work in a small office using 2 Macs on a LAN. I write applications using Obj C / XCode using Core Data and would like to enable these apps to file share over a LAN. I have scoured the internet and the ADC website in vain looking for support in terms of writing code etc. but so far have seen plenty about sqlite3 etc but nothing specific to ObjC / Core Data. In essence what I would like to achieve is something similar to File Maker Pro's ability to share files and in fact have had to resort to FM Pro to get my project off the ground. Although FM Pro is a terrific application I would still like to write my own stuff in ObjC - I would then have all the flexibility of designing my own interface and whatever functionality I could dream up. Will I have to write my own file sharing interface or is there an easier route I can go ? Any pointers will be much appreciated.
