在facebook上分享不显示文字

Question

我试图与Facebook上的内容共享图像，但它只是共享图像。内容未被分享。

var sharePhoto = FBSDKSharePhoto()
sharePhoto.caption = "Test"
sharePhoto.image = #imageLiteral(resourceName: "profile-pic-registration")
var content = FBSDKSharePhotoContent()
FBSDKShareDialog.show(from: self, with: content, delegate: nil)
