iphone - 获取 nsdictionary 中特定键的值

Question

我将 json 解析结果保存在 dictionary 中，如下所示:

{
 "statusCode":"200",
"body":[
  {
     "status":"success",
     "remarks":null
  }
],

"data":[
     "abcd":[
        {
           "category":"a",
           "title":"b",
           "id":"24"
        },
        {
           "category":"c",
           "title":"crd",
           "id":"65"
        },
        {
           "category":"ds",
           "title":"sd",
           "id":"18"
        }

     ]
  },
  {
     "efgh":[
        {
           "category":"ds",
           "title":"sd",
           "id":"18"
        },
        {
           "category":"sd",
           "title":"sd",
           "id":"1"
        }

                             ]
  },
  {
     "ijkl":[
        {
           "category":"ds",
           "title":"sd",
           "id":"18"
        },
        {
           "category":"sd",
           "title":"sd",
           "id":"1"
        }

     ]
  }
 ]
}

key @"data"的数据可以使用

保存到数组中

NSMutableArray *getdata=[[NSMutableArray alloc]init];
getcat=[results objectForKey:@"data"];

现在我应该如何处理第一个索引中的 values(category, title, id)，即 "abcd"。

如果有人有任何知识，请查看。

感谢大家。

Answer 1

下面会给你想要的对象

NSDictionary *dict=[results valueForKeyPath:@"data.abcd"][0];

对于个人:

NSString *categoryString=[[results valueForKeyPath:@"data.abcd"][0] objectForKey:@"Category"];
NSString *idString=[[results valueForKeyPath:@"data.abcd"][0] objectForKey:@"id"];
NSString *titleString=[[results valueForKeyPath:@"data.abcd"][0] objectForKey:@"title"];

此外，

NSString *categoryString=dict[@"Category"];
NSString *idString=dict[@"id"];
NSString *titleString=dict[@"title"];
