有没有办法将状态附加到FBSDKShareContent

Question

当用户将照片视频分享给应用时，我需要附上说明或状态，这是我现在的代码：

视频：

let fbVideo: FBSDKShareVideo = FBSDKShareVideo()

fbVideo.videoURL = self.videoUrl!
var content: FBSDKShareVideoContent = FBSDKShareVideoContent()
content.video = fbVideo

FBSDKShareAPI.shareWithContent(content, delegate: nil)

和图片：

    let photo : FBSDKSharePhoto = FBSDKSharePhoto()
    photo.image = self.image
    photo.userGenerated = true
    var content: FBSDKSharePhotoContent = FBSDKSharePhotoContent()
    content.photos = [photo]
    FBSDKShareAPI.shareWithContent(content, delegate: nil)

似乎无法将文本状态附加到FBSDKShareContent
