【问题描述】：

我想使用RestKit，但我已经使用Realm.io 而不是CoreData。

是否可以在 Realm.io 之上使用 RestKit？

【参考方案1】：

当然可以。从 RestKit 取回对象后：

// 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];

你需要做两件事：

创建继承自 RLMObject 的 RealmArticle 模型（在本例中）

那么你只需要写信到你的领域

RLMRealm *realm = [RLMRealm defaultRealm];

[realm beginWriteTransaction];

[RealmArticle createInDefaultRealmWithObject:article];

[realm commitWriteTransaction];
