Ios Facebook SDK似乎缺少内容标题和描述？

我使用Facebook API在Facebook上发布视频，现在我正在iOS上做同样的事情。这些API看起来非常相似，但缺少contentTitle和描述。我该怎么设置呢？我下面的API使用非常好，只是缺少了这两个字段。有人知道该怎么写吗

NSURL *videoURL = [NSURL fileURLWithPath:videoPath];
FBSDKShareVideo *video = [[FBSDKShareVideo alloc] init];

video.videoURL = videoURL;
FBSDKShareVideoContent *content = [[FBSDKShareVideoContent alloc] init];
content.video = video;

// Upload video
[FBSDKShareAPI shareWithContent:content delegate:self];

请尝试此代码，因为在此方法中，您只能共享视频，而不能共享文本和描述

 if ([[FBSDKAccessToken currentAccessToken] hasGranted:@"contact_email"]) {

    NSData *videoData = [NSData dataWithContentsOfURL:appDelegateObj.finalVideoUrl];
    NSMutableDictionary *params = [NSMutableDictionary dictionaryWithCapacity:3L];

    [params setObject:videoData forKey:@"videofilename.MOV"];
    [params setObject:@"Your post title" forKey:@"title"];
    [params setObject:@"Your post description" forKey:@"description"];

    [[[FBSDKGraphRequest alloc] initWithGraphPath:@"/me/videos" parameters:params HTTPMethod:@"POST"]
     startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
         if (!error) {
             //video posted
             NSLog(@"successfull %@:",result);
             strFbSocialPostId = [result valueForKey:@"id"];//post ID
         }
     }];
}

令人惊叹的！谢谢你的帮助。
