Can I use RestKit and Realm.io? - restkit

Question

I want to use RestKit, but I already use Realm.io instead of CoreData.
Is it possible to use RestKit on top of Realm.io?

Answer 1

Sure you can. Once you get the object back from RestKit:
// GET a single Article from /articles/1234.json and map it into an object
// JSON looks like {"article": {"title": "My Article", "author": "Blake", "body": "Very cool!!"}}
RKObjectMapping *mapping = [RKObjectMapping mappingForClass:[Article class]];
[mapping addAttributeMappingsFromArray:#[#"title", #"author", #"body"]];
NSIndexSet *statusCodes = RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful); // Anything in 2xx
RKResponseDescriptor *responseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:mapping method:RKRequestMethodAny pathPattern:#"/articles/:articleID" keyPath:#"article" statusCodes:statusCodes];
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:#"http://restkit.org/articles/1234.json"]];
RKObjectRequestOperation *operation = [[RKObjectRequestOperation alloc] initWithRequest:request responseDescriptors:#[responseDescriptor]];
[operation setCompletionBlockWithSuccess:^(RKObjectRequestOperation *operation, RKMappingResult *result) {
Article *article = [result firstObject];
// I would put the Realm write here
NSLog(#"Mapped the article: %#", article);
} failure:^(RKObjectRequestOperation *operation, NSError *error) {
NSLog(#"Failed with error: %#", [error localizedDescription]);
}];
[operation start];
You will need to do two things:
Create your RealmArticle model (in this case) that inherits from RLMObject
Then you will just need to write to your realm
RLMRealm *realm = [RLMRealm defaultRealm];
[realm beginWriteTransaction];
[RealmArticle createInDefaultRealmWithObject:article];
[realm commitWriteTransaction];
