Incorrectly parse json into NSDictionary


I am trying store text fields data into a NSDictionary from json. I have used SBJson for this.

 {  
   "fields":[  
      {  
        "textFields":[  
            {  
              "text":"Congratulations",
              "textSize":"12"
            },
            {  
               "text":"Best Wishes",
               "textSize":"15"
             },
            {  
              "text":"Test  text",
              "textSize":"10"
            }
          ]
       },
      {  
         "imageFields":[  
            {  
               "image":"test1.jpg",
               "width":"200",
           "height":"100"
        },
        {  
           "image":"test2.jpg",
           "width":"200",
           "height":"100"
            }
         ]
       }
    ]
  }

My code:

 -(void)readJson{

     NSDictionary *jsonDict = [jsonString JSONValue];
     NSDictionary *fieldsDict =[jsonDict valueForKey:@"fields"];
     NSDictionary *textFieldsDict = [fieldsDict valueForKey:@"textFields"];
     NSLog(@" Dictionary %@ ",textFieldsDict );

}

But its output as follows.

Dictionary (
     (
             {
         text = Congratulations;
         textSize = 12;
     },
             {
        text = "Best Wishes";
        textSize = 15;
    },
            {
         text = "Test  text";
         textSize = 10;
     }
 ),
 "<null>"
) 

It seems like there are two items in dictionary and one is null. I wanted to put three textfield items into the array. How can i solve this.


Solution

  • I have corrected the json format and used NSJSONSerialization, 
    
      {"fields":
       {"textFields":
        [  {"text":"Congratulations", "textSize":"12"},
           {"text":"Best Wishes", "textSize":"15"},
           {"text":"Test  text", "textSize":"10"}
        ],
      "imageFields":
       [  {"image":"test1.jpg","width":"200", "height":"100"},
          {"image":"test2.jpg", "width":"200", "height":"100"}
       ]
     }
    }
    
    
     -(void)readJson
        NSError *e = nil;
        NSDictionary *jsonDict = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:&e];
        NSDictionary *fields = [jsonDict objectForKey:@"fields"];
        NSArray *textArray=[fields objectForKey:@"textFields"] ;
        NSLog(@"--- %@",textArray );
     }
