【问题描述】：

这是我得到的服务器端的响应。 匹配是字典。 我正在使用键值，但没有帮助我。

       
    0 =     

    "shop_name" = sujeet;
    subcategory =         
        0 =             
            subcategory = "Hair cut";
            "subcategory_id" = 16;
        ;
    ;
;
1 =     

    "shop_name" = "Scissors Men's Parlour";
    subcategory =         
        0 =             
            subcategory = "Children Hair Cut";
            "subcategory_id" = 19;
        ;
    ;
;
2 =     

    "shop_name" = "Mirror Beauty Parlour";
    subcategory =         
        0 =             
            subcategory = "Beauty parlour";
            "subcategory_id" = 14;
        ;
        1 =             
            subcategory = Manicure;
            "subcategory_id" = 25;
        ;
        10 =             
            subcategory = "Wax Half Legs";
            "subcategory_id" = 34;
        ;
        11 =             
            subcategory = "Eyebrow Tint";
            "subcategory_id" = 36;
        ;
        2 =             
            subcategory = Pedicure;
            "subcategory_id" = 26;
        ;
        3 =             
            subcategory = "Facial Massage";
            "subcategory_id" = 27;

        ;
    ;
;
3 =     

    "shop_name" = "Sheela's beauty salon";
    subcategory =         
        0 =             
            subcategory = "Children Hair Cut";
            "subcategory_id" = 19;
        ;

    ;
;
;

我想将子类别和 shop_name 放在 uitableview 单元格上 我的代码 首先我想知道我得到了多少字典数

     myCount = [MAtches count];
           NSString *inStr;
            for (i = 0; i < myCount; i++)
            
                inStr = [@(i) stringValue];
                [connt addObject:inStr];

            

doing this 
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:

    cell.Shop_Name.text=[MAtches valueForKey:[connt objectAtIndex:indexPath.row]];

【问题讨论】：

有谁知道如何打印该值

你的 json 格式很难，因为你在数据中的额外键，比如 0=, 1= 它从 json 中删除的东西不需要它。 @user3189586

有什么东西可以删除那些 0=,1=

我遇到了太多的困难

您的 json 格式错误，请检查。并以这种方式纠正甲酸[ "shop_name" : "sujeet", "subcategory" :[ "subcategory" : "Hair cut", "subcategory_id" : 16, ] , "shop_name": "Scissors Men's Parlour", "subcategory" :[ "subcategory" : "Children Hair Cut", "subcategory_id" : 19, ] ]

【参考方案1】：

因为你有一个不规则的键试试这个，我尝试并使用NSDictionary：2 来做这个例子.. ;) 干杯。

NSDictionary *tempDic = @
    @"shop_name" : @"Mirror Beauty Parlour",
    @"subcategory":
       @
           @0: @
                   @"subcategory": @"Beauty parlour",
                   @"subcategory_id": @14
                ,
           @1: @
                   @"subcategory": @"Manicure",
                   @"subcategory_id": @25
               ,
           @10:@
                   @"subcategory": @"Wax Half Legs",
                   @"subcategory_id": @35
               ,
           @11:@
                   @"subcategory": @"Eyebrow Tint",
                   @"subcategory_id": @36
               ,
           @2: @
                   @"subcategory": @"Pedicure",
                   @"subcategory_id": @26
               ,
           @3: @
                   @"subcategory": @"Facial Massage",
                   @"subcategory_id": @27
               
           
       ;

---

NSLog(@"shop_name: %@", [tempDic objectForKey:@"shop_name"]);

NSDictionary *tempDict = [tempDic objectForKey:@"subcategory"];

NSArray *allKeys = [tempDict allKeys];

for (int i = 0; i < allKeys.count; i++)

    NSString *key = allKeys[i];

    NSDictionary *item = [tempDict objectForKey:key];

    NSLog(@"key:%@", key);

    NSLog(@"subcategory:%@", [item objectForKey:@"subcategory"]);

    NSLog(@"subcategory_id:%@", [item objectForKey:@"subcategory_id"]);

    NSLog(@"dictionary:%@", item);

【参考方案2】：

尝试使用此代码从您的 json 响应中获取价值

NSMutableDictionary *dict= yourdata store in dictionary;

    for (int i=0; i<[dict allKeys].count; i++) 
        NSLog(@"%@",[dict objectForKey:[NSString stringWithFormat:@"%d",i]]);// return first array object means 0 key value
        NSLog(@"%@",[[dict objectForKey:[NSString stringWithFormat:@"%d",i]] objectForKey:@"shop_name"]);// return shop name

    

在您的表委托方法中使用这种方式

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

    cell.Shop_Name.text=[[yourJsonDictionary objectForKey:[NSString stringWithFormat:@"%d",indexPath.row]] objectForKey:@"shop_name"]; // print shop name 


-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section

    return [yourJsonDictionary allKeys].count;

【参考方案3】：

如果有人遇到同样的问题

    -(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
   
   NSArray *key=[MAtches valueForKey:[connt objectAtIndex:indexPath.row]];
    cell.Shop_Name.text=[key valueForKey:@"shop_name"];
     retrn cell;
    

【参考方案4】：

处理响应：

- (void)handleResponse:(NSDictionary *)response



responseParsedDictionary = [[NSMutableDictionary alloc] init];

    for (id key in response) 
        NSMutableDictionary *subDictionary = [[NSMutableDictionary alloc] init];
        [subDictionary setObject:[[response objectForKey:key] objectForKey:@"shop_name"] forKey:@"shop_name"];
        NSDictionary *subcategory = (NSDictionary *)[[response objectForKey:key] objectForKey:@"subcategory"];
        NSMutableDictionary *subCategoryArray = [[NSMutableDictionary alloc] init];
        for (id subKey in subcategory) 
            NSMutableDictionary *subcategoryDictionary = [[NSMutableDictionary alloc] init];
            [subcategoryDictionary setObject:[[subcategory objectForKey:subKey] objectForKey:@"subcategory"]forKey:@"subcategory"];
            [subcategoryDictionary setObject:[[subcategory objectForKey:subKey] objectForKey:@"subcategory_id"]forKey:@"subcategory_id"];
            [subCategoryArray setObject:subcategoryDictionary forKey:subKey];
        
        [subDictionary setObject:subCategoryArray forKey:@"subcategory"];

        [responseParsedDictionary setObject:subDictionary forKey:key];

    
`enter code here`

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

    cell.Shop_Name.text= [[responseParsedDictionary objectForKey:[NSString stringWithFormat:@"%ld",(long)indexPath.row]] objectForKey:@"shop_name"];


-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section

    return responseParsedDictionary.count;
