When a user gets to this screen, there is no way to cancel out of it. What can I do?

To get this view in the first place I am running:

NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                               vid, @"link",
                               vid, @"source",
                               vid, @"picture",
                               @"My Place", @"name",
                               @"YouTube Presentation", @"caption",
                               title, @"description",
                               @"Enjoy this Video",  @"message",
                               nil];

[app.facebook dialog:@"stream.publish"
                   andParams:params
                 andDelegate:self];
