iphone - 関係キーを取得する方法

Question

英語で申し訳ありません:(....私はrestkitで単純なjsonをコーディングすることを知っています。しかし、非常に紛らわしいjsonは以下のようなものです。

 {
    "success": {
        "code": 1,
        "message": "Message"
    },
    "customers": [
        {
            "customerId": "182",
            "customerName": "anil",

            "ratingPoint": "10",
            "address": "adress of customer",
.
.
.

                {

                    "customerId": "182"
                },
                {

                    "evening": "",
                    "customerId": "182"
                }
            ]
        },

出力は「success」、「customers」、および「allCustomers」を取得しますが、「openingHour」の値はNULLです。

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

上記のコードのように正しいですか？「openingHour」キーの値を取得する方法がわかりません。Plzが役に立ちます

それがどのように機能するかを説明させてください：

上記のjsonはサーバーから取得しています。すべてのキーはcoredataに保存する必要があります。
'success'キーは、配列ではなくオブジェクトです。'checkInSuccess'クラスオブジェクトを保存しますが、coredataは必要ありません。
「顧客」キーは配列です。'CheckInCustomers'オブジェクトを使用してcoredataに保存されます。
'allCustomers'キーは別の配列です。'CheckInAllCustomers'オブジェクトを使用してcoredataに保存されます。
'openingHour'キーは配列です。コアデータに保存する必要があります。
'checkInOpeningHour'オブジェクトでcoredataに保存されないコードを使用しました。それが問題です。
'openingHour'配列をcoredataに保存する方法を知りたいですか？

仕組みを見る：

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);
    }

}

ここで宿題です。返される値valueForKeyが dict または array であるかどうかを確認してください。そうしないと、アプリケーションがクラッシュする可能性があります。幸せなコーディング.. :)
