swift - Facebook 共享对话框失败 - 操作无法快速完成

Question

我正在 iphone 设备上测试，用户已登录 facebook 应用程序。

在 do, catch block 中我得到错误 error is message: The operation couldn't be completed. (FacebookShare.ShareError 错误 0。)在/Users/bogdanbarbulescu/Desktop/myStreet.com/myStreet.com/MessagesViewController.swift 中的第 895 行。


我在 github 上找到了另一个建议:

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

但是，我收到错误 Use of unresolved identifier 'FBSDKShareLinkContent'。如果单击 FBSDKShareLinkContent() 并跳转到定​​义，我会进入 FBSDKSharingContent.h

我在这里做错了什么？

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

让这段代码工作

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