title: Tagging friends in Facebook videos for an iPhone app
body: <p>I am developing an iPhone application that allows the uploading of videos to Facebook. I would like to allow the user to tag his/her friends in the video uploaded. How can I achieve this programmatically? I have gone through the Facebook API documentation. There are APIs to add tags to photos, upload videos. But, the API for tagging friends for videos is not mentioned anywhere.</p>
