如何获取json数据并将Array Integer字典值打印到我的tableview单元格中

Question

我有json数据，例如

{
NetworkMembers =         (
                {
        id = 1;
        memberId = 1;
        networkId = 1;
        position = 0;
        type = H;
    },

最后，我将数组放入这样：

for (int i=0; i<[array count]; i++) { 
    NSDictionary *dictionary = [array objectAtIndex:i]; 
    NSArray *array2=[dictionary valueForKey:@"NetworkMembers"]; 
    for (int j=0; j<[array2 count]; j++) { 
        NSDictionary *dictionary2 = [array2 objectAtIndex:j]; 
        NSLog(@"J value %@",[dictionary2 valueForKey:@"type"]); 
        [self.tablArray addObject:[dictionary2valueForKey:@"type"]]; 
        [self.tablArray addObject:[dictionary2 valueForKey:@"id"]]; 
    } 
} 

最后我得到像tableArray（H，1，H，2，H，3，H，4，H，6然后在单元格中为索引路径的行我写了像

 UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"testing"];


if(!cell)
{
    cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:@"testing"];

}
cell.textLabel.text = [tablArray objectAtIndex:indexPath.row];
if([tablArray count]>0)
{
           cell.detailTextLabel.text=[[tablArray objectAtIndex:indexPath.row]stringValue];
}

return cell;

像终止应用程序由于未捕获的异常“NSInvalidArgumentException”，原因，但打印的详细文本拉布勒IAM越来越错误：“ - [__ NSCFString stringValue的]：无法识别的选择发送到实例0x109314510” *第一掷调用堆栈：预先感谢任何人可以帮助我

我认为最好使用字典的NSArray，其中包含用于类型的键和用于ID的键，因此tableArray将为：

// Create a property of tableArray to retrieve data later
@property (nonatomic, strong) NSMutableArray *tableArray

// Add data inside your tableArray your viewDidLoad
NSDictionary *dicAllNetworks = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingAllowFragments error:nil]; // Retrieve data from your JSON file inside a NSDictionary

_tableArray = [NSMutableArray array];
for (NSDictionary *dic in [dicAllNetworks objectForKey:@"NetworkMembers"])
{
    [tableArray addObject:@{@"id" : [dic objectForKey:@"id"], @"type": [dic objectForKey:@"type"]}];
}
NSLog(@"%@", tableArray);

然后您将得到如下数组：

tableArray (
        {
        id = 1;
        type = H;
    },
        {
        id = 2;
        type = H;
    }
)

然后像这样修改您的代码：

cell.textLabel.text = [[tablArray objectAtIndex:indexPath.row] objectForKey:@"type"];
if([tablArray count]>0)
{
           cell.detailTextLabel.text=[[tablArray objectAtIndex:indexPath.row] objectForKey:@"id"];
}
