如何从Objective -C中的Json响应中获取值

问题描述

我在从Json响应中获取数据时遇到问题。

I have a problem with fetching data from Json response.

以下是一个示例数据结构：

Here is an example data structure :

(
     {
        AT = "<null>";
        DId = 0;
        DO = 0;
        PLId = 33997;
        PdCatList =  (
                       {
                PLId = 33997;
                PPCId = 0;

                pdList = (
                      {
                        IsDis = 0;
                        IsPS = 0;
                        IsT = 1;
                        PA = 1;
                        PCId = 119777;
                     }
                );
            }
        );
        PdId = 0;
        SId = 0;
        Sec = 1;
    },
     {
        AT = "<null>";
        DId = 0;
        DO = 11;
        Dis = 0;
        PLId = 34006;
        PdCatList =   (
                {

                PLId = 34006;
                PPCId = 0;
                pdList =  (
                       {
                        IsDis = 0;
                        IsPS = 0;
                        IsT = 1;
                        PA = 1;
                        PCId = 119830;
                       },
                       {
                        IsDis = 0;
                        IsPS = 0;
                        IsT = 1;
                        PA = 1;
                        PCId = 119777;
                       }
                   );
              },

             {
                PLId = 33997;
                PPCId = 0;
                pdList = (
                      {
                        IsDis = 0;
                        IsPS = 0;
                        IsT = 1;
                        PA = 1;
                        PCId = 119777;
                     }
                );
            }

        );
        PdId = 0;
        SId = 0;
        Sec = 1;
    },
)

我将如何解析生成的结构？
我想直接得到一个值列表。如果我在tupel中有多个值，例如执行者PdCatList，pdList，该怎么办？我将如何访问这些值？
任何人都可以帮助我

how would i parse the resulting Structure ?I would like to get a list of values directly. What if i have several values in a tupel for example performer PdCatList, pdList. How would i access those values?Can anyone help me

谢谢

我的代码是

NSError *error;
    Array1 = [NSJSONSerialization JSONObjectWithData:responseData options:kNilOptions error:&error];

    for(int i=0;i<[Array1 count];i++)
    {
        NSDictionary *dict1 = [Array1 objectAtIndex:i];

        NSLog(@"Array1.....%@",dict1);

        Array2=[dict1 valueForKey:@"PdCatList"];

        for(int i=0;i<[Array2 count];i++)
        {

            NSDictionary *dict2 = [Array2 objectAtIndex:i];

            NSLog(@"Array2.....%@",dict2);

            Array3=[dict2 valueForKey:@"pdList"];

            for(int i=0;i<[Array3 count];i++)
            {

                NSDictionary *dict3 = [Array3 objectAtIndex:i];

                NSLog(@"Array3.....%@",dict3);

            }


        }


    }

推荐答案

试试这个......

Try this...

NSError *error;
Array1 = [NSJSONSerialization JSONObjectWithData:responseData options:kNilOptions error:&error];

for(int i=0;i<[Array1 count];i++)
{
    NSDictionary *dict1 = [Array1 objectAtIndex:i];

    ATArray =[dict1 valueForKey:@"AT"];
    DIdArray =[dict1 valueForKey:@"DId"];
    DOArray =[dict1 valueForKey:@"DO"];
    PLIdArray =[dict1 valueForKey:@"PLId"];

    etc...

    Array2=[dict1 valueForKey:@"PdCatList"];

    for(int i=0;i<[Array2 count];i++)
    {

        NSDictionary *dict2 = [Array2 objectAtIndex:i];

        PLIdArray =[dict2 valueForKey:@"PLId"];
        PPCIdArray =[dict2 valueForKey:@"PPCId"];

        etc…

        Array3=[dict2 valueForKey:@"pdList"];

        for(int i=0;i<[Array3 count];i++)
        {

            NSDictionary *dict3 = [Array3 objectAtIndex:i];

            IsDisArray =[dict3 valueForKey:@"IsDis"];
            IsPSArray =[dict3 valueForKey:@"IsPS"];
            IsTArray =[dict3 valueForKey:@"IsT"];
            PAArray =[dict3 valueForKey:@"PA"];
            PCIdArray =[dict3 valueForKey:@"PCId"];
        }
    }
}
