ios - 无法打开 Facebook Messenger 从 iOS 应用分享视频

Question

我想使用以下代码在 Facebook Messenger 中分享我的 iOS 应用程序中的视频：

NSURL *videoURL = [NSURL fileURLWithPath:[self.myViewController getSharingVideoPath]];
FBSDKShareVideo *video = [[FBSDKShareVideo alloc] init];
video.videoURL = videoURL;
FBSDKShareVideoContent *content = [[FBSDKShareVideoContent alloc] init];
content.video = video;
[FBSDKShareDialog showFromViewController:self withContent:content delegate:nil];

这是 videoURL 的输出：

file:///private/var/mobile/Containers/Data/Application/13D19738-5F9E-4C77-A502-0E18F5D09A10/Documents/anonymous/MyApp/144229926301/MyVideo.mov

当我运行时，没有错误，但 Facebook Messenger 没有打开。

我从

https://developers.facebook.com/docs/sharing/ios 

这是

- (void)imagePickerController:(UIImagePickerController *)picker
didFinishPickingMediaWithInfo:(NSDictionary *)info
{
  NSURL *videoURL = [info objectForKey:UIImagePickerControllerReferenceURL];

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