我是restkit的新手，我对此有疑问。我有一个登记入住的休息服务。所以我用“Put”请求调用我的休息服务。看起来像这样放：http：.../api/v1/locations/location/[Location-ID]/checkin?userId=[User-ID]。响应是 a ，所以我称它为 checkin-object。签入后即时调用另一个服务（获取请求）。但是获取请求的新映射结果包括先前的签入对象。我如何重置/擦除它？

[self.restHelper checkinUser:[NSNumber numberWithInt:USER_ID] forLocationID:self.selectedLocation success:successBlock failure:failureBlock];

映射：

- (void)checkinUser:(NSNumber*) userID forLocationID:(NSNumber *)locationID success:(void (^)(RKObjectRequestOperation *, RKMappingResult *))success failure:(void (^)(RKObjectRequestOperation *, NSError *))failure{

RKObjectManager *objectManager = [RKObjectManager sharedManager];

RKObjectMapping *userCheckinMapping = [RKObjectMapping mappingForClass:[CheckIN class]];
[userCheckinMapping addAttributeMappingsFromDictionary:@{
 @"locationFullname" : @"locationFullname",
 @"userNameCityCountry" : @"userNameCityCountry",
 @"success" : @"success",
 }];

RKResponseDescriptor *responseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:userCheckinMapping pathPattern:nil keyPath:@"" statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)];

[objectManager addResponseDescriptor:responseDescriptor];

NSString *path = [NSString stringWithFormat:@".../api/v1/locations/location/%@/checkin?userId=%@", locationID,userID];

[objectManager putObject:nil path:path parameters:nil success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {
    success(operation, mappingResult);
} failure:^(RKObjectRequestOperation *operation, NSError *error) {
    failure(operation,error);
}];

}

下一个电话是这样的：

 -(void)getTracksForLocation:(NSNumber *)locationID withType:(NSString*) type success:(void (^)(RKObjectRequestOperation *, RKMappingResult *))success failure:(void (^)(RKObjectRequestOperation *, NSError *))failure{

RKObjectManager *objectManager = [RKObjectManager sharedManager];

RKObjectMapping *trackResultsMapping = [RKObjectMapping mappingForClass:[RESTTracksResult class]];
[trackResultsMapping addAttributeMappingsFromDictionary:@{
 @"id" : @"ID",
 @"cued" : @"cued",
 @"marked" : @"marked",
 @"playing": @"playing",
 @"played": @"played",
 @"creditBidSum": @"creditBidSum",
 }];

RKObjectMapping *trackMapping = [RKObjectMapping mappingForClass:[RESTTrack class]];
[trackMapping addAttributeMappingsFromDictionary:@{
 //@"id" : @"ID",
 @"name" : @"name",
 @"artistName" : @"artistName",
 @"genre": @"genre",
 @"length": @"length",
 }];

RKRelationshipMapping* relationShipMapping = [RKRelationshipMapping relationshipMappingFromKeyPath:@"track"
                                                                                         toKeyPath:@"track"
                                                                                       withMapping:trackMapping];

[trackResultsMapping addPropertyMapping:relationShipMapping];


RKResponseDescriptor *responseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:trackResultsMapping pathPattern:nil keyPath:@"results" statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)];

[objectManager addResponseDescriptor:responseDescriptor];

NSDictionary *trackDictionary = @{ @"type": type};

NSString *path = [NSString stringWithFormat:@".../api/v1/locations/location/%@/tracks", locationID ];

[objectManager getObjectsAtPath:path parameters:trackDictionary success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {
    success(operation, mappingResult);
} failure:^(RKObjectRequestOperation *operation, NSError *error) {
    failure(operation,error);
}];

}

希望你能帮助我，泰！我也试过删除缓存，但没有用！

您做错了一些事情，这意味着当您进行第二次调用时，第一次调用的所有配置都被用于尝试理解第二次响应。

1.

当您使用对象管理器时，您应该设置基本 URL。你可能已经这样做了，很难说。然后，每当您指定路径时，它都应该相对于该基础。

2.

创建路径时，不要添加参数。这就是parametersput 和 get 方法的参数的用途。

3.

如果您使用的是sharedManager，您应该一次性完成所有映射配置。不要在每次调用方法时添加额外的映射。

4.

创建响应描述符时，设置路径模式和关键路径。这是你的主要问题。如果您不设置它们，RestKit 将始终尝试使用机架映射来处理每个响应。这将导致您在映射结果中获得意外的对象，可能会赢得部分信息。
