Facebook ShareDialog总是返回，完成时取消

共享对话框打开Facebook应用程序，尽pipe内容共享成功，我总是收到.cancelledcallback。 在这两种情况下 – 当我取消共享，当共享成功。 任何想法是什么错误？ 豆荚版本：

Using Bolts (1.8.4) Using FBSDKCoreKit (4.20.2) Using FBSDKLoginKit (4.20.2) Using FBSDKShareKit (4.20.2) Using FacebookCore (0.2.0) Using FacebookLogin (0.2.0) Using FacebookShare (0.2.0) 

显示对话框的代码片段：

  @IBAction func onShareClicked(_ sender: UIButton) { do{ var myContent = LinkShareContent(url: URL(string: "https://www.facebook.com/8MinuteWorkoutChallenge")!) myContent.hashtag = Hashtag("#8MWC") let shareDialog = ShareDialog(content: myContent) shareDialog.mode = .native shareDialog.failsOnInvalidData = true shareDialog.completion = { result in switch result { case .success: print("Share succeeded") case .failed: self.shareButton.isHidden = true case .cancelled: print("Share cancelled") } } try shareDialog.show() } catch { print("Error: \(error)") } }

Answer 1

使用下面的代码来显示当前View控制器的FB共享对话框：

 { let shareDialog: FBSDKShareDialog = FBSDKShareDialog() shareDialog.shareContent = content shareDialog.delegate = self shareDialog.fromViewController = self shareDialog.show() } 

这适用于我分享链接到Facebook。 您可以使用委托方法来获取共享状态callback。

首先，检查是否授予publish action权限，如果是，则share您的content 。 否则，获得用户的许可，在他们的时间表上发布post，然后在授予权限的情况下共享post。

  if FBSDKAccessToken.current().hasGranted("publish_actions") { if FBSDKShareAPI().self.canShare() { FBSDKShareAPI.share(with: videoContent, delegate: self) } else { print("Graph API can not share your video") } } else { // Get publish_actions permission from fb app and upload photo to share. let loginManager = FBSDKLoginManager() loginManager.logIn(withPublishPermissions: ["publish_actions"], from: fromViewController, handler: { (result, error) in if result != nil && error == nil { if FBSDKShareAPI().self.canShare() { FBSDKShareAPI.share(with: videoContent, delegate: self) } else { print("Graph API can not share your video") } } else if error != nil { print("Error in sharing photo:- \(error!)") } }) }
