ios - Facebook ShareDialog 在完成时始终返回 .canceled

Question

共享对话框打开 Facebook 应用程序，尽管内容已成功共享，但我总是收到 .cancelled 回调。在这两种情况下 - 当我取消共享时和共享成功时。知道出了什么问题吗？ Pod 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)")
    }
}

使用下面的代码向当前 View Controller 显示 FB 共享对话框:

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

这可以让我分享 Facebook 的链接。您可以使用委托(delegate)方法来获取共享状态回调。
