title: How to convert JSON serialized data to NSDictionary
body: <p>I have used this method,</p>
  
  <pre><code>NSDictionary *jsonObject=[NSJSONSerialization 
         JSONObjectWithData:jsonData 
                    options:NSJSONReadingMutableLeaves 
                      error:nil];
  NSLog(@"jsonObject is %@",jsonObject);
  </code></pre>
  
  <p>It's printing "jsonObject is null".<br>
  Is there any problem with "error:nil".<br>
  I am not using any url or connection methods.<br>
  I have a json file and I want to display it in a table.</p>
