所以，我第一次发送 POST 请求。我是映射类，并且我认为并从文档中读到它会以这种方式工作：

初始化 RK：

- (void)initRK{
    if(!manager){
        manager = [RKObjectManager managerWithBaseURL:[NSURL URLWithString:BASE_CONTEXT_URL]];
    }

    if (!reqMapping) {
        reqMapping = [RKObjectMapping requestMapping];
    }
}

POST 方法：

// Configure a request mapping for our Article class. We want to send back title, body, and publicationDate
RKObjectMapping* deviceRequestMapping = [RKObjectMapping mappingForClass:[DeviceDTO class]];
[deviceRequestMapping addAttributeMappingsFromArray:@[ @"model", @"name", @"systemName", @"systemVersion", @"devToken" ]];

RKObjectMapping* msRequestMapping = [RKObjectMapping mappingForClass:[MemberShipDTO class]];
[msRequestMapping addAttributeMappingsFromArray:@[ @"validSince", @"validTill" ]];

RKObjectMapping* countryRequestMapping = [RKObjectMapping mappingForClass:[CountryDTO class]];
[countryRequestMapping addAttributeMappingsFromArray:@[ @"idNumberDTO", @"iso2DTO", @"short_nameDTO", @"calling_codeDTO" ]];

RKObjectMapping* userRequestMapping = [RKObjectMapping requestMapping];
[userRequestMapping addAttributeMappingsFromArray:@[ @"displayName", @"phoneNumber", @"status", @"userID" ]];

[userRequestMapping addPropertyMapping:[RKRelationshipMapping relationshipMappingFromKeyPath:nil toKeyPath:@"device" withMapping:deviceRequestMapping]];
[userRequestMapping addPropertyMapping:[RKRelationshipMapping relationshipMappingFromKeyPath:nil toKeyPath:@"memberShip" withMapping:msRequestMapping]];
[userRequestMapping addPropertyMapping:[RKRelationshipMapping relationshipMappingFromKeyPath:nil toKeyPath:@"country" withMapping:countryRequestMapping]];

RKRequestDescriptor *requestDescriptor = [RKRequestDescriptor requestDescriptorWithMapping:userRequestMapping objectClass:[User class] rootKeyPath:@"user"];


//Create Objects
UserDTO *user = [[UserDTO alloc]init];
user.displayName = userDTO.displayName;
user.phoneNumber = userDTO.phoneNumber;
user.status = userDTO.status;
user.userID = userDTO.userID;
user.country = userDTO.country;

DeviceDTO *device = [[DeviceDTO alloc]init];
device.name = devDTO.name;
device.systemName = devDTO.systemName;
device.systemVersion = devDTO.systemVersion;
device.model = devDTO.model;
device.devToken = [[NSUserDefaults standardUserDefaults]objectForKey:PUSHTOKEN_USER_DEFAULTS_KEY];

user.deviceInfo = device;

MemberShipDTO *ms = [[MemberShipDTO alloc]init];
ms.validSince = [NSDate date];
ms.validTill = [[UtilitieHandler new] getDateByAdd:+1 :0 :0 :0];

user.memberShipDetails = ms;

[RKMIMETypeSerialization registerClass:[RKNSJSONSerialization class] forMIMEType:@"application/json"];

[[RKObjectManager sharedManager] setRequestSerializationMIMEType:RKMIMETypeJSON];
[[RKObjectManager sharedManager] setAcceptHeaderWithMIMEType:RKMIMETypeJSON];
[[RKObjectManager sharedManager] addRequestDescriptor:requestDescriptor];
[[RKObjectManager sharedManager] postObject:user path:@"user/integrate" parameters:nil success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult){
    RKLogInfo(@"Load collection of Articles: %@", mappingResult.array);
}failure:^(RKObjectRequestOperation *operation, NSError *error) {
    RKLogError(@"Operation failed with error: %@", error);
}];

所以我尝试了不同的方法，在我使用wireshark 捕获它返回的请求后，没有发送任何内容。这意味着映射工作不正确。我尝试了很多，但没有任何帮助。任何建议都会很棒！

这里捕获的数据包：

这可能只是您的问题中的一个错字，但requestDescriptor似乎没有链接到 UserDTO 类。

您似乎还没有了解 Core Data 对象。使用 Core Data 持久化的对象是 NSManagedObject 的子类，必须以不同的方式创建。进一步阅读此链接：http: //developer.apple.com/library/mac/#documentation/cocoa/conceptual/CoreData/Articles/cdCreateMOs.html

至于当前的问题，您必须改用它：

NSEntityDescription *entity = [NSEntityDescription entityForName:@"UserDTO" inManagedObjectContext:[RKManagedObjectStore defaultStore].mainQueueManagedObjectContext];

UserDTO *user = [[NSManagedObject alloc] initWithEntity:entity insertIntoManagedObjectContext:nil];

但是，如果 UserDTO 是 NSObject 的子类，则需要更改为 NSManagedObject。

我的工作流程是这样的——创建核心数据模型并使用 mogenerator 自动生成 NSManagedObject 类定义。在此处阅读更多信息：http ://raptureinvenice.com/getting-started-with-mogenerator/
