Facebook共享对话框失败-操作无法迅速完成

Question

我正在测试一个on iphone设备，用户登录到facebook应用程序。

在do, catch块中，我得到了错误error is message: The operation couldn’t be completed. (FacebookShare.ShareError error 0.) on line 895 in /Users/bogdanbarbulescu/Desktop/myStreet.com/myStreet.com/MessagesViewController.swift.

我在github上发现了另一个建议：

   let content = FBSDKShareLinkContent()
   content.contentURL = URL(string: "https://developers.facebook.com")
   FBSDKShareDialog.show(from: self, with: content, delegate: self)     

但是，我得到了错误的Use of unresolved identifier 'FBSDKShareLinkContent'。如果单击FBSDKShareLinkContent()并跳转到定义，我就会得到FBSDKSharingContent.h。

我在这里做错什么了？

import UIKit
import FacebookShare
import FacebookCore
import FacebookLogin

   class MessagesVC {

  func invitePeopleTapped() {

     let alertController = UIAlertController(title: "Some title", message: "", preferredStyle: .actionSheet)
    let shareOnFacebook = UIAlertAction(title: "Share on Facebook", style: .default) { _ in

        let linkContent = LinkShareContent(url: URL(string: "https://www.google.com")!, quote: "Discover & Talk ")

        let shareDialog = ShareDialog(content: linkContent)
            shareDialog.mode = .native
            shareDialog.failsOnInvalidData = true

        shareDialog.completion = { result in
           print("the result is \(result)")
        }

        do {
            try shareDialog.show()
        } catch {
            printsNow(message: error.localizedDescription)

        }
    }
     alertController.addAction(shareOnFacebook)
     self.present(alertController, animated: true, completion: nil)
  } //end invitePeopleTapped

 } //end class

你错过了图书馆

import FBSDKShareKit

此代码才能正常工作

let content = FBSDKShareLinkContent()
content.contentURL = URL(string: "https://developers.facebook.com")
FBSDKShareDialog.show(from: self, with: content, delegate: self)
