FBSDKSharePhoto not sharing link alongside photo using Swift

问题

When I try to share a link along with a picture, at the same time, via FBSDKSharePhoto, only the photo gets shared. No link appears.

Here is the code I use:

let photo : FBSDKSharePhoto = FBSDKSharePhoto()
photo.image = self.scaledImage
photo.userGenerated = true

let content : FBSDKSharePhotoContent = FBSDKSharePhotoContent()
content.contentURL = NSURL(string: self.short_string)
content.photos = [photo]

let button : FBSDKShareButton = FBSDKShareButton()
button.shareContent = content

And a picture of the resulting dialog when I push the button: http://imgur.com/mZ483i9 (also attached)

You can see the picture gets attached to the post, but there is no link. I know all of the URL/Photo variables work fine because they are used elsewhere.

If I switch the sharing method to FBSDKShareLinkContent then content.contentURL works fine, but I cannot post the picture this way because the picture is not hosted on the web, which is why I am using FBSDKSharePhotoContent. (The picture is taken within the app.)

let content : FBSDKShareLinkContent = FBSDKShareLinkContent()
content.contentURL = NSURL(string: self.short_string)
content.contentTitle = self.title_text
content.contentDescription = self.desc_text
content.imageURL = NSURL(string: "http://randomimage.jpg/")

let button : FBSDKShareButton = FBSDKShareButton()
button.shareContent = content

So I know my link is structured properly according to the contentURL protocol, and FBSDKSharePhotoContent conforms to the same functions as FBSDKShareLinkContent. No clue why it won't work.

Due to Facebook rules you can`t set non user generated text.
