ObjectiveResource is an Objective-C implementation of ActiveResource, which allows interaction with RESTful Ruby on Rails applications.
It’s still a work in progress, and quite early on. There is no support for modifying records yet, and there is no relationship support. If you need improvements to the framework, either make them yourself and send a pull request so you can contribute it back :) or send me a message and I’ll see if I can help.
To use it, just make a subclass for your model:
@interface Product : ObjectiveResource
@end
And implement (at least) +baseURL in your subclass:
@implementation Product
+ (NSString*)baseURL { return @"http://example.com"; }
@end
There are a few other class methods you can override for configuration, see the interface in Base.h.
Then you can use it to fetch records:
NSArray* products = [Product findAll:nil];
Or a record with a specific ID:
Product* product = [Product find:1];
NSString* title = [product valueForKey:@"title"];
an exception will be thrown if the record is not found (or if there is a problem with the connection or resource).
