What's the suggested way to exchange structure data among iOS devices?

Question

Take Purchase Order as an example. There is Purchase Order header and one or more rows of Purchase Order details :

            +--- PO detail 1
            |
PO header --+--- PO detail 2
            | 
           ...
            | 
            +--- PO detail n

Assuem the POs are stored in a Core Data database. What's the suggested way to exchange some PO records among iOS devices, using the same app? I am thinking of packing the records in json format, zip and email to recipient(s). Is there any built-in mechanism in Core Data to serialize data in one device and de-serialize in another device? Thanks!

Answer 1

There is no built in API for translating the data. I recommend and use JSON as a transport format. I wrote a generic (and rough) recursive parser in answer to another StackOverflow question .
