Question

我有一个API，我正在查询当我查询组织列表时，我得到了一个数组：

{ 
    id: integer,
    name: string
}

但我也能够获得每个返回单个对象的组织的详细信息，如：

{ 
    id: integer,
    name: string,
    description: text,
    visit_count: integer,
    image_url: string
}

我如何在RestKit中设置对象？

Answer 1

您需要设置以下内容：

包含您在第二个块中描述的所有元素的对象

对象管理器

RKObjectManager *objectManager = [RKObjectManager managerWithBaseURL:[NSURL URLWithString:YOUR HOST NAME]];
objectManager.requestSerializationMIMEType=RKMIMETypeJSON;

包含对象中所有元素的映射对象

RKObjectMapping *mapping = [RKObjectMapping mappingForClass:[YOUR CLASS class]];

对象的映射

[mapping addAttributeMappingsFromArray:@[@"id",
                                         @"name",
                                         @"description",
                                         @"visit_count",
                                         @"image_url"
                                         ]];

响应描述符

RKResponseDescriptor *responseDesciptor = [RKResponseDescriptor responseDescriptorWithMapping:mapping method:RKRequestMethodAny pathPattern:OBJECT URL keyPath:YOUR KEY PATH statusCodes:nil];

将响应描述符添加到对象管理器
```
[objectManager responseDesciptor];
```

现在你可以点击服务器了

[[RKObjectManager sharedManager] postObject:nil path:OBJECT URL parameters:nil
     success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {
         self.variable = [NSMutableArray arrayWithArray: mappingResult.array];
     }
 } failure:^(RKObjectRequestOperation *operation, NSError *error) {

        UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"An Error Has Occurred" message:[error localizedDescription] delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
        [alertView show];

  }];
