ios - NSDictionary 到 NSMutableArray

Question

这是我的 API 响应 -

{"kitchen":"3","bath":"5","lanundry":"0","dining":"0","bedroom":"0"}

我已将它加载到 NSDictionary 中，我可以使用像这样的键检索值

NSDictionary *pdata = [NSJSONSerialization JSONObjectWithData: data options:NSJSONReadingMutableContainers error:nil];    
[pdata objectForKey:@"dining"]

我想将 dictionary 对象添加到 NSMutableArray 中，但它会用最后一个覆盖所有数组值，即使它添加了五个记录。

itemsA=[[NSMutableArray alloc] init];


imgCount *img=[[imgCount alloc] init];

 if([pdata objectForKey:@"kitchen"])
    {

       [img setCount:[pdata objectForKey:@"kitchen"]];
       [img setDesc:@"Kitchen"];

       [itemsA addObject:img];
    }
 if([pdata objectForKey:@"bath"])
    {
       [img setCount:[pdata objectForKey:@"bath"]];
       [img setDesc:@"Bathroom"];
       [itemsA addObject:img];
     }
 if([pdata objectForKey:@"lanundry"])
     {
        [img setCount:[pdata objectForKey:@"lanundry"]];
        [img setDesc:@"Laundry"];
        [itemsA addObject:img];
      }
 if([pdata objectForKey:@"dining"])
      {
         [img setCount:[pdata objectForKey:@"kitchen"]];
         [img setDesc:@"Kitchen"];
         [itemsA addObject:img];
       }
  if([pdata objectForKey:@"bedroom"])
      {
        [img setCount:[pdata objectForKey:@"bedroom"]];
        [img setDesc:@"Bedroom"];
        [itemsA addObject:img];
      }

我的 TableView 显示 5 行，最后一个值 -

Bedroom (0)

但我想要这样的结果

{"desc":"bathroom","count":"0"}, {"desc":"dining","count":"3"}

为此，您可以这样尝试。首先获取字典的所有键，然后使用该键数组创建字典数组。

NSArray*keys=[dict allKeys];
NSMutableArray *array = [[NSMutableArray alloc] init];
for (NSString *key in keys) {
    NSDictionary *dic = @{ @"desc":key, @"count": [dict objectForKey:key] };
    [array addObject:dic];
}
NSLog(@"Array - %@",array);

编辑:如果您想要自定义类对象，您可以这样尝试。

 for (NSString *key in keys) {
    imgCount *imgObject=[[imgCount alloc] init];
    [imgObject setCount:[pdata objectForKey:key]];
    [imgObject setDesc:[key capitalizedString]];        
    [array addObject:imgObject];
}
