Code for syncing the iPhone with REST-servers

Question

is there any open source code for syncing an iPhone with a server (preferably REST)?

Found nothing on github and google code.

Regards...

Answer 1

I have been working with a project called ObjectiveResource (Github project here: http://github.com/yfactorial/objectiveresource/tree/master), which is focused mainly on the communication layer between your iphone models and a REST based web service. It is targeted at rails applications but should work with any REST api. Part of that project is a more sync oriented solution that is still in early development, but which has been discussed quite a bit lately in the objective resource google group at http://groups.google.com/group/objectiveresource?hl=en.

I highly recommend objective resource, I've been using it along with sqlitepersistenobjects to handle sync on my iphone project.

I suggest using the excellent ASIHTTPRequest source from All-Seeing Interactive: http://allseeing-i.com/ASIHTTPRequest. I'm doing this, and so are several released iPhone apps, so you can be sure the code is pretty solid.

This is a wrapper around the CFNetwork API that makes some of the more tedious aspects of communicating with web servers easier. It is written in Objective-C and works in both Mac OS X and iPhone applications.

It is suitable for performing basic HTTP requests and interacting with REST-based services (GET / POST / PUT / DELETE). The ASIFormDataRequest subclass makes it easy to submit POST data and files using multipart/form-data.

I would recommend checking out RestKit: http://restkit.org/ It provides an excellent API for accessing RESTful web services and representing the remote resources as local objects, including persisting them to Core Data.

I've used Adrian Kosmaczewski's iPhone Rest Wrapper with success. See also this SO question.
