Hello, Is this a copy/paste effect or your datasource methods are not public ? In order to be exported, the methods tagged with "ObjectiveCMessage" must be public.
Moreover, by setting the environment variable MONOBJC_DEBUG to 3, you can see what the bridge exports for each classes; see http://www.monobjc.net/index.php?page=advanced-debugging for more information.
