Iphone 如何获取关系密钥

对不起，英语：（……我知道用restkit编写简单的json。但是非常混乱的json如下所示

 {
    "success": {
        "code": 1,
        "message": "Message"
    },
    "customers": [
        {
            "customerId": "182",
            "customerName": "anil",
            "email": "anil@yahoo.com",
            "customerAbout": "To show the customer details",
            "customerLogoSmall": "http://server.com/ thumb/1.jpg",
            "customerLogoLarge": "http://server.com/ 2.jpg",
            "ratingPoint": "10",
            "address": "adress of customer",
.
.
.
            "openingHour": [
                {
                    "day": "monday",
                    "morning": "10to12.30",
                    "evening": "1to6",
                    "customerId": "182"
                },
                {
                    "day": "sunday",
                    "morning": "",
                    "evening": "",
                    "customerId": "182"
                }
            ]
        },
        {
            "customerId": "183",
            "customerName": "miche",
            "email": "babu@yahoo.com",
            "customerAbout": "To show the customer details",
            "customerLogoSmall": "http://server.com/ thumb/1.jpg",
            "customerLogoLarge": "http://server.com/ 2.jpg",
            "ratingPoint": "10",
.
.
.
            "openingHour": [
                {
                    "day": "monday",
                    "morning": "10to12.30",
                    "evening": "1to6",
                    "customerId": "183"
                },
                {
                    "day": "sunday",
                    "morning": "",
                    "evening": "",
                    "customerId": "183"
                }
            ]
        }
    ],
    "allCustomers": [
        {
            "customerId": "182"
        },
        {
            "customerId": "183"
        }
    ]
}

//CheckInCustomerOpeningHour.h（用于“openingHour”键）

输出将获得“success”、“customers”和“allCustomers”，但“openingHour”值为空

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

像上面的代码一样正确吗？我不知道如何获取“openingHour”键的值。请帮助我

编辑： 让我解释一下它是如何工作的：

• 上面的json来自我们的服务器。所有密钥都需要保存到coredata中
• “成功”键是对象而不是数组。它将保存“checkInSuccess”类对象，但不需要coredata
• “customers”键是数组。它将使用“CheckInCustomers”对象保存到coredata
• “allCustomers”键是另一个数组。它将使用“CheckInAllCustomers”对象保存到coredata
• “openingHour”键是一个数组。我们需要保存到核心数据
• 我使用的代码不会保存到带有“checkInOpeningHour”对象的coredata。这就是问题所在
• 我想知道如何在coredata中保存“openingHour”数组

了解它的工作原理：

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);
    }

}

NSDictionary*dictionary=[yourParser parse:jsonString]；
对于（int i=0；i<[dictionary valueForKey:@“customers”]计数]；i++）{
NSArray*openingHourArray=[[[dictionary valueForKey:@“customers”]objectAtIndex:i]valueForKey:openingHour]；
对于（int j=0；j如何解析JSON，使用SBJson之类的东西？RSKit在解析JSON后是否返回NSDictionary？？？@rptwsthi是…有问题吗？很好，没有问题infacr问题解决：但是customerRelationShip getting为NULL。infacr？这是什么…我们从未使用过。我需要存储到coredata获取值的键是“openingHour”通过这个，你可以从你的JSON数据字典中获得开放时间字典。如果没有帮助，那么请详细解释你真正想要什么。你知道RestKit吗？如果知道，我会向其他人解释…：）对不起，大家。上面我的代码是正确的。我的另一个代码中有一行的问题。这已经修复。
