계층형에 내부 반복 (Array) 로 복잡한 json 문자열 생성하기

이번 미션에서는 어떠한 데이터를 받아서 json문자열을 생성 해야  한다.

지금 까지는 간단한 key :  value 형태의 json 문자열을 생성하여  WAS통신 하는 앱을 개발 했는데 그것은 간단한 NSArray 의 key value를 SBJson 모듈에 넣어서 생성 하면 간단 했다.

이번의 경우는

     timezone

     activity

        -- startTime

        -- stopTime

        -- calorie

        -- detail

            --startTime

            --stopTime

            --stepCnt

            -- distance

            -- mode

     sleep

        -- startTime

        -- stopTime

        -- calorie

        -- detail

            -- startTime

            -- stopTime

            -- settingstartTime

            -- settingstopTime

     

            mode

위와 같은 json 형태가 되는데 active 의 하위 key가 있고 그중 detail은 또 하위를 가지며

detal은 mode에 따라서 여러번 반복된다.

마찬가지로 sleep도 마찬가지이다.

    //sleep.detail

    NSMutableDictionary * sleep_detail1 = [[NSMutableDictionary alloc] init];

    [sleep_detail1 setValue:@"200" forKey:@"startTime"];

    [sleep_detail1 setValue:@"200" forKey:@"stopTime"];

    [sleep_detail1 setValue:@"200" forKey:@"settingstartTime"];

    [sleep_detail1 setValue:@"200" forKey:@"settingstopTime"];

    [sleep_detail1 setValue:@"Awake" forKey:@"mode"];

    NSMutableDictionary * sleep_detail2 = [[NSMutableDictionary alloc] init];

    [sleep_detail2 setValue:@"200" forKey:@"startTime"];

    [sleep_detail2 setValue:@"200" forKey:@"stopTime"];

    [sleep_detail2 setValue:@"200" forKey:@"settingstartTime"];

    [sleep_detail2 setValue:@"200" forKey:@"settingstopTime"];

    [sleep_detail2 setValue:@"Light Sleep" forKey:@"mode"];

    NSMutableDictionary * sleep_detail3 = [[NSMutableDictionary alloc] init];

    [sleep_detail3 setValue:@"200" forKey:@"startTime"];

    [sleep_detail3 setValue:@"200" forKey:@"stopTime"];

    [sleep_detail3 setValue:@"200" forKey:@"settingstartTime"];

    [sleep_detail3 setValue:@"200" forKey:@"settingstopTime"];

    [sleep_detail3 setValue:@"Deep Sleep" forKey:@"mode"];

    NSArray *sleep_detail_array = [NSArray arrayWithObjects: sleep_detail1,

                                   sleep_detail2,

                                   sleep_detail3,

                                   nil ];

    

    //sleep

    NSMutableDictionary * sleepData = [[NSMutableDictionary alloc] init];

    [sleepData setValue:@"200" forKey:@"startTime"];

    [sleepData setValue:@"200" forKey:@"stopTime"];

    [sleepData setValue:sleep_detail_array forKey:@"detail"];

    [sleepData setValue:@"200" forKey:@"calorie"];

    

    

    //activity.detail

    NSMutableDictionary * activity_detail1 = [[NSMutableDictionary alloc] init];

    [activity_detail1 setValue:@"200" forKey:@"startTime"];

    [activity_detail1 setValue:@"200" forKey:@"stopTime"];

    [activity_detail1 setValue:@"200" forKey:@"stepCnt"];

    [activity_detail1 setValue:@"200" forKey:@"distance"];

    [activity_detail1 setValue:@"Non-move" forKey:@"mode"];

    NSMutableDictionary * activity_detail2 = [[NSMutableDictionary alloc] init];

    [activity_detail2 setValue:@"200" forKey:@"startTime"];

    [activity_detail2 setValue:@"200" forKey:@"stopTime"];

    [activity_detail2 setValue:@"200" forKey:@"stepCnt"];

    [activity_detail2 setValue:@"200" forKey:@"distance"];

    [activity_detail2 setValue:@"Walking" forKey:@"mode"];

    NSMutableDictionary * activity_detail3 = [[NSMutableDictionary alloc] init];

    [activity_detail3 setValue:@"200" forKey:@"startTime"];

    [activity_detail3 setValue:@"200" forKey:@"stopTime"];

    [activity_detail3 setValue:@"200" forKey:@"stepCnt"];

    [activity_detail3 setValue:@"200" forKey:@"distance"];

    [activity_detail3 setValue:@"Fast Walking" forKey:@"mode"];

    NSMutableDictionary * activity_detail4 = [[NSMutableDictionary alloc] init];

    [activity_detail4 setValue:@"200" forKey:@"startTime"];

    [activity_detail4 setValue:@"200" forKey:@"stopTime"];

    [activity_detail4 setValue:@"200" forKey:@"stepCnt"];

    [activity_detail4 setValue:@"200" forKey:@"distance"];

    [activity_detail4 setValue:@"Running" forKey:@"mode"];

    NSArray *activity_detail_array = [NSArray arrayWithObjects: activity_detail1,

                                   activity_detail2,

                                   activity_detail3,

                                   activity_detail4,

                                   nil ];

    

    //activity

    NSMutableDictionary * activity = [[ NSMutableDictionary alloc] init];

    [activity setValue:@"200" forKey:@"statTime"];

    [activity setValue:@"200" forKey:@"stopTime"];

    [activity setValue:activity_detail_array forKey:@"detail"];

    [activity setValue:@"200" forKey:@"calorie"];

    

    //sync

    NSMutableDictionary * sync = [[ NSMutableDictionary alloc] init];

    [sync setValue:@"SEOUL" forKey:@"timezone"];

    [sync setValue:activity forKey:@"activity"];

    [sync setValue:sleepData forKey:@"sleep"];

    

    NSError *err;

    NSData *jsonData = [NSJSONSerialization dataWithJSONObject:sync options:NSJSONWritingPrettyPrinted error:&err];

    

    NSLog(@"JSON = %@", [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding]);

실제 디버깅 정보로 위에서 생성한 데이터가 json 문자열로 어떻게 생성되었는지 확인해보면

다음과 같다.

JSON = {

  "timezone" : "SEOUL",

  "activity" : {

    "stopTime" : "200",

    "detail" : [

      {

        "startTime" : "200",

        "stopTime" : "200",

        "stepCnt" : "200",

        "distance" : "200",

        "mode" : "Non-move"

      },

      {

        "startTime" : "200",

        "stopTime" : "200",

        "stepCnt" : "200",

        "distance" : "200",

        "mode" : "Walking"

      },

      {

        "startTime" : "200",

        "stopTime" : "200",

        "mode" : "Running"

      }

    ],

    "statTime" : "200",

      },

      {

        "startTime" : "200",

        "stopTime" : "200",

        "settingstopTime" : "200",

        "settingstartTime" : "200",
