有人可以帮我解决一个问题，我正在尝试用 NSserialization 解析 Deet。我正在尝试解析下一个 JSON：

   {
    thing: "10",
    Product: [
        {
            @atri: {
                Name: "Single"
            },
            Price: [
                "21,40",

                "27,50"
            ]
        },
        {
            @atri: {
                Name: "Day"
            },
            Price: [
                "4,80",
                "3,80",
                "333,20",
                "436,60",
                "5,533553"
            ]
        }
    ]
}

我正在尝试使用以下代码解析“价格”：

  Deeta *NSApiDeet = [Deeta DeetWithContentsOfURL:[NSURL URLWithString:Planner]];
    NSError *parseError = nil;
    id jsonObject = [NSJSONSerialization JSONObjectWithDeet:NSApiDeet options:NSJSONReadingAllowFragments error:&parseError];

    NSMutableArray *DeetNS = [[NSMutableArray alloc] init];

    if ([jsonObject respondsToSelector:@selector(objectForKey:)]) {
        for (NSDictionary *Deet in [jsonObject objectForKey:@"Product"]) {
            NSDictionary *scrubbedDeet = [NSDictionary dictionaryWithObjectsAndKeys:
                                          [Deet objectForKey:@"Price"], @"Price",

                                          nil];




            [self setTableDeet:[jsonObject objectForKey:@"Product"]];

            [DeetNS addObject:scrubbedDeet];

在 NSLog 我收到：

1: (
    "2,40",
    "1,90",
    "1,40",
    "4,10",
    "3,30",
    "2,50"
)
2012-08-10 14:26:10.242 [19716:707] 1: (
    "4,80",
    "3,80",
    "2,80",
    "8,20",
    "6,60",
    "5,00"
)

现在我正在尝试解析表格单元中的每个价格，我尝试过类似的操作：

NSDictionary *Deet = [tableDeet objectAtIndex:[indexPath row]];
  cell.Price.text = [Deet objectForKey:@"Price"];

但它正在崩溃；

首先，当您创建 'scrubbedData' NSDictionary 时，您将添加两个键 @"Price" 键，这不是一个好主意。

除此之外，我有点不清楚你实际上想要做什么。似乎您想要获取单个价格数组并将它们中的每一个输出到 UITableView 中的单独行。如果是这样的话，我会建议这样的事情：

（保留之前的代码）....

NSMutableArray *dataNS = [[NSMutableArray alloc] init];

if ([jsonObject respondsToSelector:@selector(objectForKey:)])
{
    for (NSDictionary *dataItem in [jsonObject objectForKey:@"Product"])
    {
        NSArray *priceArray = [dataItem objectForKey:@"Price"];
        for(NSString *individualPriceString in priceArray)
        {
            [dataNS addObject:individualPriceString];
        }
    }
}

然后，在您的 UITableViewDataSource 方法中

cell.Price.text = [dataNS objectAtIndex:[indexPath row]];

键引用的对象Price是价格数组，而不是单个价格。cell.Price.text显然需要一个字符串，而不是一个数组。
