所以我正在尝试使用 Restkit 0.20 映射没有 KVC 的 JSON 对象

没有 KVC 的 JSON

{
    "created_at": "2013-03-11T22:13:05Z",
    "facebookId": "2343434322",
    "firstname": "testuser",
    "id": 197,
    "mail": "test@gmail.com",
    "name": "test",
    "phone": "098748394",
    "sex": null,
    "twitterId": null,
    "updated_at": "2013-03-11T22:13:05Z",
    "vehiculeDescription": "car",
    "recommendCount": 0
}

我的应用委托

RKObjectManager *manager = [RKObjectManager managerWithBaseURL:[NSURL URLWithString:WEBSERVICE]];

// Initialize managed object store
NSURL *modelURL = [NSURL fileURLWithPath:[[NSBundle mainBundle]      pathForResource:@"KojoClient" ofType:@"momd"]];
// NOTE: Due to an iOS 5 bug, the managed object model returned is immutable.
NSManagedObjectModel *managedObjectModel = [[[NSManagedObjectModel alloc] initWithContentsOfURL:modelURL] mutableCopy];
RKManagedObjectStore *managedObjectStore = [[RKManagedObjectStore alloc] initWithManagedObjectModel:managedObjectModel];
manager.managedObjectStore = managedObjectStore;

RKEntityMapping *utilisateurMapping =
    [RKEntityMapping mappingForEntityForName:NSStringFromClass([Utilisateur class]) inManagedObjectStore:manager.managedObjectStore];
utilisateurMapping.identificationAttributes = @[@"remoteid"];
[utilisateurMapping addAttributeMappingsFromDictionary:@{
    @"remoteid": @"id",
    @"name": @"name",
    @"firstname": @"firstname",
    @"phone": @"phone",
    @"facebookid": @"facebookId",
    @"mail": @"mail",
    @"vehiculeDescription" : @"vehiculeDescription",
    @"recommendCount" : @"recommendCount",
    @"created_at": @"created_at",
    @"updated_at": @"updated_at",
    @"twitterId": @"twitterId"
 }];

/**
 Register our mappings with the provider
 */


RKResponseDescriptor* utilisateursDescriptor =
[RKResponseDescriptor responseDescriptorWithMapping:[utilisateurMapping inverseMapping]
                                        pathPattern:@"/utilisateurs"
                                            keyPath:@""
                                        statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)];

RKResponseDescriptor* utilisateurDescriptor =
    [RKResponseDescriptor responseDescriptorWithMapping:[utilisateurMapping inverseMapping]
                                            pathPattern:@"/utilisateurs/:remoteid"
                                            keyPath:@""
                                            statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)];
RKResponseDescriptor* facebookUtilisateurDescriptor =
                                            [RKResponseDescriptor responseDescriptorWithMapping:[utilisateurMapping inverseMapping]
                                            pathPattern:@"/face_utilisateurs/:facebookid"
                                            keyPath:@""
                                            statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)];

[manager addResponseDescriptorsFromArray:@[utilisateursDescriptor, utilisateurDescriptor, facebookUtilisateurDescriptor]];

// Serialize to JSON
manager.requestSerializationMIMEType=RKMIMETypeJSON;

/**
 Complete Core Data stack initialization
 */

[managedObjectStore createPersistentStoreCoordinator];

NSString *storePath = [RKApplicationDataDirectory() stringByAppendingPathComponent:@"Application.sqlite"];
NSError *error;

NSPersistentStore *persistentStore = [managedObjectStore addSQLitePersistentStoreAtPath:storePath fromSeedDatabaseAtPath:nil  withConfiguration:nil options:@{NSMigratePersistentStoresAutomaticallyOption:@YES, NSInferMappingModelAutomaticallyOption:@YES} error:&error];

NSAssert(persistentStore, @"Failed to add persistent store with error: %@", error);

// Create the managed object contexts
[managedObjectStore createManagedObjectContexts];

// Configure a managed object cache to ensure we do not create duplicate objects
managedObjectStore.managedObjectCache = [[RKInMemoryManagedObjectCache alloc] initWithManagedObjectContext:managedObjectStore.persistentStoreManagedObjectContext];

问题是当我想获得我的对象时：

[[RKObjectManager sharedManager] getObjectsAtPath:path parameters:nil success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {

                 if(![[mappingResult firstObject] isKindOfClass:[Utilisateur class]]) {
                     //Dont work
                 }

             } nil];

RKMappingResult 对象没有类。

未知类图像

但是映射工作

mappingResult->_keyPathToMappedObjects 的打印描述： { "" = {​​ "created_at" = "2013-03-11T22:13:05Z"; facebookid = 4567898765; 名字 = 测试；邮件=“test@gmail.com”；名称 = 测试名称；电话 = 45678976587；推荐计数 = 0; 远程ID = 197；"updated_at" = "2013-03-11T22:13:05Z"; 车辆描述 = “测试”；}; }

我不明白为什么我的对象映射没有类。

我遵循了没有 KVO 的对象映射教程

并且无法更改服务器 JSON 样式。

我尝试不使用 NSStringFromClass，不工作。

为什么你使用[utilisateurMapping inverseMapping]for RKResponseDescriptorwith RKEntityMapping？也许如果你尝试：

RKResponseDescriptor* utilisateursDescriptor =
[RKResponseDescriptor responseDescriptorWithMapping:utilisateurMapping
                                        pathPattern:@"/utilisateurs"
                                            keyPath:@""
                                        statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)];
