title: receiving collection element of type int is not an objective c object in iOS
body: <p>I have the following dictionary:</p>
  
  <pre><code>NSDictionary* jsonDict = @{
                                 @"firstName": txtFirstName.text,
                                 @"lastName": txtLastName.text,
                                 @"email": txtEmailAddress.text,
                                 @"password": txtPassword.text,
                                 @"imageUrl": imageUrl,
                                 @"facebookId": [fbId integerValue],
                                };
  </code></pre>
  
  <p>In the last element, I need to use an integer, but I am receiving the error:</p>
  
  <pre><code>collection element of type int is not an objective c object
  </code></pre>
  
  <p>How can I use an int value in this element?</p>
