Answer 1

Based on @Kashifs solution. Here is a version in Swift 4.2, Xcode 10 and FacebookSDK 4.4.

  import FBSDKShareKit

extension YourViewController: UIActivityItemSource{

    //MARK: - ActionSheet

    func showShareSheet(){
        let shareStr = "Text you want to share"
        let activItems =  [self,shareStr, #imageLiteral(resourceName: "YourImageName")] as [Any]
        let shareSheet = UIActivityViewController(activityItems: activItems, applicationActivities: nil)
        self.shareSheet = shareSheet
        self.present(shareSheet, animated: true, completion: nil)
    }


    //MARK: - FacebookPost

    func postToFacebook() {
        let quote = "Text you want to share"
        if let URL = URL(string: "https://yourURL"){
            let content : LinkShareContent = LinkShareContent(url: URL, quote: quote)
            let dialog = ShareDialog(content: content)
            dialog.mode = .shareSheet
            dialog.presentingViewController = self
            do{
                try dialog.show()
            }catch{
                print("\(error)")
            }
        }
    }


    //MARK: - UIActivityItemSource Protocol

    func activityViewController(_ activityViewController: UIActivityViewController, itemForActivityType activityType: UIActivity.ActivityType?) -> Any?{
        if activityType == UIActivity.ActivityType.postToFacebook{
            self.shareSheet?.dismiss(animated: true, completion: {
                self.postToFacebook()
            })
        }
        return nil
    }

    func activityViewControllerPlaceholderItem(_ activityViewController: UIActivityViewController) -> Any {
        return ""
    }
