Question

我的json数据位于第一个数组I主类别数组中，名称为“Response”，其中我有父类别数组，名称为“0”，其中我有名为“0”的子类别数组这是我的json格式

{"Response":[{"menuname":"Jewellery","menuid":"1","0":[{"catname":"Rings","catid":"1","0":[{"scatname":"Engagement Rings","scatid":"4"},{"scatname":"Wedding Rings","scatid":"5"},{"scatname":"kk","scatid":"35"}]},{"catname":"Pendants","catid":"2","0":[{"scatname":"Office Wear","scatid":"8"}]},{"catname":"Bracelets","catid":"3","0":[{"scatname":"Studded","scatid":"9"}]},{"catname":"Earrings","catid":"6","0":[{"scatname":"Ethnic Jhumkas","scatid":"7"}]},{"catname":"Chain's","catid":"33","0":[]},{"catname":"Jewel","catid":"34","0":[]}]},{"menuname":"Collections","menuid":"2","0":[{"catname":"SOUND OF LOVE","catid":"15","0":[{"scatname":"LOVE BRACELET","scatid":"16"}]},{"catname":"COLORFUL AFFAIR","catid":"17","0":[{"scatname":"Passion ring","scatid":"18"}]},{"catname":"Evermore Collection","catid":"19","0":[]},{"catname":"BOARDROOM GLAM ","catid":"20","0":[]},{"catname":"ETERNAL GOLD","catid":"21","0":[]},{"catname":"FASHIONISTA COLLECTION","catid":"22","0":[]}]},{"menuname":"Gold Coin","menuid":"3","0":[{"catname":"SOUND OF LOVE","catid":"15","0":[{"scatname":"LOVE BRACELET","scatid":"16"}]},{"catname":"COLORFUL AFFAIR","catid":"17","0":[{"scatname":"Passion ring","scatid":"18"}]},{"catname":"Evermore Collection","catid":"19","0":[]},{"catname":"BOARDROOM GLAM ","catid":"20","0":[]},{"catname":"ETERNAL GOLD","catid":"21","0":[]},{"catname":"FASHIONISTA COLLECTION","catid":"22","0":[]}]},{"menuname":"OFF THE SHELF","menuid":"4","0":[{"catname":"testing from pixel","catid":"13","0":[]},{"catname":"New pixel","catid":"23","0":[]},{"catname":"Evermore Collection","catid":"19","0":[]},{"catname":"BOARDROOM GLAM ","catid":"20","0":[]},{"catname":"ETERNAL GOLD","catid":"21","0":[]},{"catname":"FASHIONISTA COLLECTION","catid":"22","0":[]}]}]}

我希望在可扩展的tableview中显示如下

Jewellery
  Rings
     Engagement Rings
     Wedding Rings
     kk
  Pendants
     Ofice Wear
Collections
  Sound Of  Love
     Love bracelet
  Colorful Affair
     Passion ring

以下是我在viewdidLoad

中使用的代码

 NSDictionary *pJson;
    NSMutableString *postStr = [NSMutableString stringWithString:kURL];
  [postStr appendString:[NSString stringWithFormat:@"?tag=%@&id=%@",kCategoryFilter,kPrecious]];

    [postStr setString:[postStr stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
    NSMutableURLRequest *request = [[NSMutableURLRequest alloc]initWithURL:[NSURL URLWithString:postStr]];
    NSLog(@"%@",postStr);
    [request setHTTPMethod:@"POST"];
    _connection = [[NSURLConnection alloc]initWithRequest:request delegate:self startImmediately:YES];
    NSURL *url = [NSURL URLWithString:postStr];
    NSData *data = [NSData dataWithContentsOfURL:url];
    pJson = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:nil];
    NSLog(@"%@",pJson);
    NSMutableArray *arr = [pJson objectForKey:@"Response"];
    NSLog(@"%lu",(unsigned long)arr.count);
    NSMutableDictionary *dict2 =[[NSMutableDictionary alloc]init];// [arr objectAtIndex:NSIndexPath.row];
   [dict2 setObject:arr forKey:@"dictionary1"];
   dict2 = [arr objectAtIndex:0];
   NSArray *arr1 =[dict2 objectForKey:@"0"];
    NSLog(@"%lu",(unsigned long)arr1.count);
    NSUInteger y;
    for (int i=0;i<arr.count;i++) {
              NSString *ring_data = [[arr objectAtIndex:i]objectForKey:@"menuname"];
        NSString *id_data = [[arr objectAtIndex:i]objectForKey:@"menuid"];
        NSLog(@"AUTHOR: %@",ring_data);
        NSLog(@"%@",id_data);
        dictionary = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                      ring_data,@"menuname",id_data,@"menuId",nil];
        [myObject addObject:dictionary];
        NSMutableArray *arr1 = [dict2 objectForKey:@"0"];
        NSLog(@"%lu",(unsigned long)arr1.count);
        y = arr.count;
        for (NSUInteger i=0;i<arr1.count;i++) {
            NSArray *count = [[[arr1 objectAtIndex:i] objectForKey:arr]valueForKey:@"catname"];
            NSString *myCount = [NSString stringWithFormat:@"%lu",(unsigned long)[count count]];
            NSString *ring_data = [[arr1 objectAtIndex:i]objectForKey:@"catname"];
            NSLog(@"AUTHOR: %@",ring_data);
            //  NSLog(@"%@",catname_data);
            dictionary1 = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                          ring_data,@"catname",
                          nil];
            [myObject1 addObject:dictionary1];

        }      
}

我为你尝试了一些代码。关注代码并自定义要添加到数组的位置以及设置字典的位置。

NSDictionary *jsonArray = [NSJSONSerialization JSONObjectWithData:responseData options: NSJSONReadingMutableContainers error: &err];

NSArray *array=[jsonArray objectForKey:@"Response"];

for (int i=0;i<[array count];i++)
{
    NSMutableDictionary *dict = [array objectAtIndex:i];
    NSMutableArray *arrayDictValue = [dict valueForKey:[NSString stringWithFormat:@"%d",0]];
    NSString *strMenuName = [NSString stringWithFormat:@"%@",[arrayDictValue valueForKey:@"menuname"]];
    NSString *strMenuID = [NSString stringWithFormat:@"%@",[arrayDictValue valueForKey:@"menuid"]];
    NSLog(@"The strMenuName is-%@",strMenuName);
    NSLog(@"The strMenuID is-%@",strMenuID);
    for (int j=0; j<[arrayDictValue count]; i++)
    {
        NSMutableDictionary *dictInside = [arrayDictValue objectAtIndex:j];
        NSArray *arrayInsideDict = [dictInside valueForKey:@"0"];
        for (int k =0; k<[arrayInsideDict count]; i++)
        {

            NSString *strCatName = [NSString stringWithFormat:@"%@",[[arrayInsideDict objectAtIndex:k ]valueForKey:@"catname"]];
            NSString *strCatID = [NSString stringWithFormat:@"%@",[[arrayInsideDict objectAtIndex:k ]valueForKey:@"catid"]];
            NSLog(@"The strCateName is-%@",strCatName);
            NSLog(@"The strCatID is-%@",strCatID);
            NSMutableDictionary *dictInArray = [[arrayInsideDict objectAtIndex:0] valueForKey:@"0"];
            NSString *strSCatName = [NSString stringWithFormat:@"%@",[dictInArray valueForKey:@"scatname"]];
            NSString *strSCatID = [NSString stringWithFormat:@"%@",[dictInArray valueForKey:@"scatid"]];
            NSLog(@"the strSCatName is - %@",strSCatName);
            NSLog(@"the strSCatID is - %@",strSCatID);

        }


    }
