Swift：使用ActivityViewController共享视​​频仅适用于iMessages，不适用于任何其他视频

Question

var selectedVideoArray: Array<Any> = []

func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath)
{
if (shareEnabled) {
            let selectedVideo = fetchResult[indexPath.row]
            self.selectedVideos.add(selectedVideo)

            var videoPhAsset: PHAsset!
            videoPhAsset = fetchResult.object(at: indexPath.row)

            PHImageManager.default().requestAVAsset(forVideo: videoPhAsset, options: nil, resultHandler: { (AVAsset, AVAudio, info) in

                var assetVideoUrl: NSURL
                var avUrlAsset: AVURLAsset
                avUrlAsset = AVAsset as! AVURLAsset
                assetVideoUrl = (avUrlAsset.url as? NSURL)!
                self.selectedVideoArray.append(assetVideoUrl.filePathURL!)
            })
        }
}


@IBAction func shareVideos(_ sender: Any) {

let moreAction = UIAlertAction(title: "More", style: UIAlertActionStyle.default) { (action) -> Void in

            let activityViewController = UIActivityViewController(activityItems: self.selectedVideoArray, applicationActivities:nil)

            activityViewController.popoverPresentationController?.sourceView = self.view // so that iPads won't crash

            self.present(activityViewController, animated: true, completion: nil)
        }

        let dismissAction = UIAlertAction(title: "Close", style: UIAlertActionStyle.cancel) { (action) -> Void in

        }

        actionSheet.addAction(moreAction)
        actionSheet.addAction(dismissAction)

        present(actionSheet, animated: true, completion: nil)
}

我正在尝试使用社交框架和ActivityViewController分享视频，但它仅适用于iMessages，不适用于任何其他社交网络或邮件。请帮帮我

社交网络不支持使用默认共享表进行视频共享。您需要为所有网络分别使用自定义方法分享视频..
