Can somebody tell me how to retrieve the thumbnail of an attachment? I would like to use the function "thumbnail" of the class AGSAttachment to visualize the thumbnails in a tableview, but I do not how to code it.
For existing attachments: The AGSAttachment::thumbnail is available when you download them with AGSAttachmentManager::downloadAttachmentDataForId: method.
For new attachments: If you add new attachment with AGSAttachmentManager's add attachment methods.
