Json如何请求转换为本地对象或列表？

Question

{
"id": "1",
"result": [
{
"Name": "John",
"Statu": "Online"
},
{
"Name": "Alex",
"Statu": "Online"
},
{
"Name": "Diaz",
"Statu": "Offline"
}
]
}

如何提取每个“汽车” JSON对象并将其放入本机对象？ 我尝试了几种方法，但我做不到。

    NSString *responseString = [[[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding] autorelease];

       NSString *responseDict = [responseString JSONValue]; 

       NSArray *objects = [NSArray arrayWithObjects:[responseDict valueForKeyPath:@"result.Name"],[responseDict valueForKeyPath:@"result.Statu"],nil];
       NSLog(@"objects Array: %@",objects);



     **==> NSLOG gives:
                      (
                        (
                        "John",
                        "Alex",
                        "Diaz"
                        ),
                        (
                        "Online",
                        "Online",
                        "Offline"
                        )
                      )



    NSArray *resultsArray = [responseString JSONValue];

     for (NSDictionary *personDict in resultsArray) 
        {

       NSLog(@"ihaleAdi =: %@",[carDict valueForKey:@"result.ihaleAdi"]);

       NSLog(@"ihaleDurum =: %@",[carDict valueForKey:@"result.Statu"]);

       }

但是，我也想给他们一个错误，但我不能这样做，请问有人可以帮助我吗？ 谢谢你的阅读

使用数组来捕获responseString：

NSString *responseString = [request responseString];
NSArray *array = [responseString JSONValue];

然后，当您需要该数组中的单个项目时，请使用字典：

// 0 is the index of the array you need
NSDictionary *itemDictionary = (NSDictionary *)[array objectAtIndex:0];

给定一个如下所示的JSON responseString：

[{“ UniqueID”：111111，“ DeviceName”：“ DeviceName1”，“ Location”：“ Device1Loc”，“ Description”：“ Device1Desc”}，{“ UniqueID”：22222，“ DeviceName”：“ DeviceName2”，“位置“：” Device2Loc“，”描述“：” Device2Desc“}]

您将得到一个看起来像这样的数组：

myArray = (
        {
        Description = "Device1Desc";
        DeviceName = "DeviceName1";
        Location = "Device1Loc";
        UniqueID = 111111;
    },
        {
        Description = "Device2Desc";
        DeviceName = "DeviceName2";
        Location = "Device2Loc";
        UniqueID = 222222;
    }
)

索引为0的字典如下所示：

myDictionary = {
    Description = "Device1Desc";
    DeviceName = "DeviceName1";
    Location = "Device1Loc";
    UniqueID = 111111;
}

对于任何混乱和较早实例化的对象，我们深表歉意。 我还是一个相对的新手，今天学到了一些东西。
