Question

I have an iphone app that lets users post a ‘story’ to their facebook wall. This story contains a youtube video as part of the message. The video loads and plays normally from the standard web-browser facebook client, but fails to load from the iphone facebook app. When the user selects the video link from the iPhone facebook app a blank white view is pushed onto the navigation controller view-stack. Is there a way to get the link to trigger the iOS to load the youtube app?

SBJSON *jsonWriter = [[SBJSON new] autorelease];

        NSDictionary* actionLinks = [NSArray arrayWithObjects:[NSDictionary dictionaryWithObjectsAndKeys: 
                                                               @"#####",@"text",
                                                               @"http://www.facebook.com/#####",@"href",
                                                               nil], nil];

        NSString *actionLinksStr = [jsonWriter stringWithObject:actionLinks];

        NSString *video_link = @"http://www.youtube.com/v/#####";
        NSString *image_link = @"http://i.ytimg.com/vi/#####/2.jpg";

        NSString *description = @"";
        NSString *name = @"#####";
        NSString *url = @"http://www.#####.com/";

        NSDictionary* attachment = [NSDictionary dictionaryWithObjectsAndKeys:
                                    name, @"name",

        NSString *attachmentStr = [jsonWriter stringWithObject:attachment];

        NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
