어떻게 얻기에 관계 키

Question

영어 죄송합니다 :(.... 내가 restkit 간단한 JSON을 코딩 할 알고있다. 그러나 매우 혼란 JSON은 다음과 같다. 'openingHour를 들어

('allCustomers'키의 경우) // 매핑 코드

RKObjectManager *objectManager = [[OPRestKit sharedDataManager] objectManager];

    [success_Mapping mapKeyPath:@"code" toAttribute:@"code"]; 
    [success_Mapping mapKeyPath:@"message" toAttribute:@"message"]; 
    [objectManager.mappingProvider setMapping:success_Mapping forKeyPath:@"success"]; 


    RKManagedObjectMapping *openingHour_Mapping = [RKManagedObjectMapping mappingForClass:[CheckInCustomerOpeningHour class] 
                    inManagedObjectStore:objectManager.objectStore]; 
    openingHour_Mapping.primaryKeyAttribute = @"customerId"; 
    [openingHour_Mapping mapKeyPath:@"customerId" toAttribute:@"customerId"]; 
    [openingHour_Mapping mapKeyPath:@"day" toAttribute:@"day"]; 
    [openingHour_Mapping mapKeyPath:@"evening" toAttribute:@"evening"]; 
    [openingHour_Mapping mapKeyPath:@"morning" toAttribute:@"morning"]; 


    RKObjectMapping *hour_Mapping = [RKObjectMapping mappingForClass:[checkInOpeningHour class]]; 
    [hour_Mapping mapKeyPath:@"openingHour" toRelationship:@"openingHourData" withMapping:openingHour_Mapping]; 


    RKManagedObjectMapping *getCustomer_Mapping = [RKManagedObjectMapping mappingForClass:[CheckInCustomers class]

    [getCustomer_Mapping mapKeyPath:@"customerId" toAttribute:@"customerId"]; 
    [getCustomer_Mapping mapKeyPath:@"address" toAttribute:@"address"]; 
    [getCustomer_Mapping mapKeyPath:@"alreadyRated" toAttribute:@"alreadyRated"];

    RKManagedObjectMapping *getAllCustomer_Mapping = [RKManagedObjectMapping mappingForClass:[CheckInAllCustomers class] 
                    inManagedObjectStore:objectManager.objectStore];

    RKObjectMapping *c_Mapping = [RKObjectMapping mappingForClass:[checkInRoot class]]; 
    [c_Mapping mapKeyPath:@"customers" toRelationship:@"customersData" withMapping:getCustomer_Mapping]; 
    [c_Mapping mapKeyPath:@"allCustomers" toRelationship:@"allCustomersData" withMapping:getAllCustomer_Mapping]; 

    [objectManager.mappingProvider registerMapping:c_Mapping withRootKeyPath:@""]; 

출력은 'openingHour'값이 NULL 인 '고객'과 'allCustomers'그러나 '성공'을 얻을 것이다.

[getCustomer_Mapping mapKeyPath:@"openingHour" toRelationship:@"customerRelationShip" withMapping:openingHour_Mapping]; 

은 위의 코드와 동일합니까? 내가 어떻게 openingHour '키'의 값을 얻는 것을 알고 DNT Plz은 나에게 도움이

편집 :.

작동 원리 설명해 보자. json으로 위

• 우리의 서버에서 점점 모든
• 'successIn'키는 'checkInSuccess'클래스 객체를 저장합니다.하지만, coredata는 필요 없습니다.
• '고객'키는 배열입니다. '고객'키는 ' CheckInCustomers '객체
• 'allCustomers'키가 다른 배열입니다. 그것은 'CheckInAllCustomers'객체로 coredata에 저장합니다.
• 'openingHour'키는 배열입니다. 핵심 데이터에 저장해야합니다.
• 'checkInOpeningHour'개체와 함께 coredata에 저장하지 않을 코드를 사용했습니다. 그것이 문제입니다.
• 알고 싶습니다. 어떻게 열어서 '열어'배열을 저장합니까?

Answer 1

은 어떻게 작동 참조 : valueForKey에 의해 반환되는 값은 DICT 또는 배열 인 경우 여기

NSDictionary *dictionary = [yourParser parse: jsonString]; 
for (int i= 0; i < [[dictionary valueForKey:@"customers"] count]; i++) { 
    NSArray *openingHourArray = [[[dictionary valueForKey:@"customers"] objectAtIndex:i] valueForKey: openingHour]; 

    for(int j = 0; j <[openingHourArray count]; j++){ 
     NSDictionary *openingHourDictionary = [openingHourArray objectAtIndex:i]; 
     NSLog(@"openingHourDictionary =%@", openingHourDictionary); 
    } 

}

이, 그에 따라 확인합니다. 그렇지 않으면 응용 프로그램이 중단됩니다. 해피 Coading .. :)
