我可以使用RestKit和Realm.io吗？

Question

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

是否可以在Realm.io上使用RestKit？

Answer 1

当然可以。从RestKit获取对象后：

// 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];

您需要做两件事：

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

2. 然后你只需要写你的领域

   RLMRealm *realm = [RLMRealm defaultRealm];
   
   [realm beginWriteTransaction];
   
   [RealmArticle createInDefaultRealmWithObject:article];
   
   [realm commitWriteTransaction];
