分享视频在Facebook上失败(Sharing video on Facebook fails)

我使用Facebook的SDK 3.1.1在Facebook上分享的视频。我在这里提到的代码。

FBRequestConnection *newConnection = [[FBRequestConnection alloc] init];

    // for each fbid in the array, we create a request object to fetch
    // the profile, along with a handler to respond to the results of the request
    NSString *fbid = @"me";
    // create a handler block to handle the results of the request for fbid's profile
    FBRequestHandler handler =
    ^(FBRequestConnection *connection, id result, NSError *error) {
        // output the results of the request
        [self requestCompleted:connection forFbID:fbid result:result error:error];
    };

    // create the request object, using the fbid as the graph path
    // as an alternative the request* static methods of the FBRequest class could
    // be used to fetch common requests, such as /me and /me/friends

    NSData *videoData = [NSData dataWithContentsOfFile:path];
    NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                   videoData, @"video.mov",
                                   @"video/quicktime", @"contentType",
                                   @"Video", @"title",
                                   @"Video Test Description", @"description",
                                   @"hello",@"subdescription",
                                   nil];
    FBRequest *request = [[FBRequest alloc] initWithSession:theDelegate.session graphPath:@"me/videos" parameters:params HTTPMethod:@"POST"];
    //:FBSession.activeSession graphPath:@"me/?fields=location"];

    // add the request to the connection object, if more than one request is added
    // the connection object will compose the requests as a batch request; whether or
    // not the request is a batch or a singleton, the handler behavior is the same,
    // allowing the application to be dynamic in regards to whether a single or multiple
    // requests are occuring
    [newConnection addRequest:request completionHandler:handler];

    // if there's an outstanding connection, just cancel
    [self.requestConnection cancel];

    // keep track of our connection, and start it
    self.requestConnection = newConnection;
    [newConnection start];

它是正确的早期工作。我每次启动上传视频请求时，我得到的共享的视频ID响应。不过，我不断收到以下消息时，我检查我的个人资料在FB里的通知。
