title: Unable to Save AFNetworking responseObject
body: <p>I'm calling a web service using <code>AFNetworking</code> and saving the return data in <code>NSDictionary</code> object. But nothing's being stored in it, even when data is successfully logged in <code>NSLog()</code>.</p>
  
  <p>This is my dictionary:</p>
  
  <pre><code>@property (strong, nonatomic) NSDictionary *newsItems;
  </code></pre>
  
  <p>and this is my codes:</p>
  
  <pre><code>AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
      NSDictionary *parameters = @{@"key": @"keyy", @"q": @"ads" };
      [manager POST:BaseURLString parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {
          self.newsItems = (NSDictionary *) responseObject;
          NSLog(@"JSON: %@", responseObject);
      } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
          NSLog(@"Error: %@", error);
      }];
  </code></pre>
