ios - NSDictionary到NSMutableArray

这是我的API响应-

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

我已经将其加载到NSDictionary中，并且可以使用以下键检索值：

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

我想将dictionary对象添加到NSMutableArray中，但是即使添加了五个记录，它也会用最后一个覆盖所有数组值。

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];
      }

我的表格视图显示5个行的最后一个值-

Bedroom (0)

但是我想要这样的结果

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

最佳答案

代码的问题是，您仅创建一个img对象并重新使用它。由于所有对象都是通过Objective-C中的引用访问的，因此您需要在所有if条件下创建单独的img对象。尝试这个

itemsA=[[NSMutableArray alloc] init];

 if([pdata objectForKey:@"kitchen"])
    {
       imgCount *img=[[imgCount alloc] init];
       [img setCount:[pdata objectForKey:@"kitchen"]];
       [img setDesc:@"Kitchen"];

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