Ios 如何获取json数据并将数组整数值的字典打印到我的tableview单元格中

Haii我有json数据，比如

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

最后，我将其放入如下数组：

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"]]; 
    } 
} 

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

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

但打印详细文本标签时，我遇到了如下错误

提前感谢有人能帮我吗

我想最好是得到一个字典数组，其中包含一个类型键和一个id键，因此

表数组

将是：

// 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);

您将得到如下阵列：

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"]]; 
    } 
} 

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

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

接下来，按如下方式修改代码：

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"]]; 
    } 
} 

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

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

我把ony type和id放在数组中，我在表单元格中获取type，但有一个问题是详细文本标签您的数组不包含nsstring，而我认为它包含NetworkMembers。因此，您必须在获取或插入数组时进行类型转换。首先，在控制台中打印

tableArray

它是什么样子的？在收到JSON时添加代码，我将向您展示如何获取dictionarytableArray数组的数组（H，1，H，2，H，3，H，4，H，6）我只接受类型和田园诗，但在这里，您无法正确使用此数组，因为您不知道该类型的id。相信我，由于未捕获的异常“NSInvalidArgumentException”，dictionary将更适合Youterming应用程序，原因：'-[\uu NSCFString objectForKey:]：未识别的选择器发送到实例0x109542850'***第一次抛出调用堆栈：它将崩溃我收到相同的消息
