通过ios应用程序(Swift和FBSDK4.0.1)将照片分享到Facebook后，无法获得结果帖子ID

Question

我正在编写一个iOS应用程序来共享照片。

使用 Swift 和 FBSDK 4.0.1 技术

我发现照片共享由FBSDKSharePhotoContent（）无法从方法 didCompleteWithResults 内部FBSDKSharingDelegate的结果对象获取任何帖子 ID 。
结果对象包含空行：

[:]

但是，FBSDKShareLinkContent（） 的 URL 共享可以从结果对象中取回帖子 ID。像这样：

[postId: 10000844250000_146108069750000]

我的核心代码的一部分：

1. 图像选取器控制器 （ UIImagePickerControllerDelegate ， UINavigationControllerDelegate ）

   func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject : AnyObject]) {
   var theImage:UIImage = info[UIImagePickerControllerOriginalImage] as! UIImage
   uploadImage.image = theImage
   self.dismissViewControllerAnimated(false, completion: nil)
   }
   

2. 选择照片后，单击自定义共享按钮

    @IBAction func postButtonClick(sender: AnyObject) {
      let photoContent = FBSDKSharePhotoContent()
      let photo : FBSDKSharePhoto = FBSDKSharePhoto()
      photo.image = uploadImage.image
      photo.userGenerated = true
      photoContent.photos = [photo]
      FBSDKShareDialog.showFromViewController(self, withContent: photoContent, delegate:self)
   }
   

3. 脸书FBSDKSharingDelegate

    func sharer(sharer: FBSDKSharing!, didCompleteWithResults results: [NSObject: AnyObject])
    {
       println("sharer didCompleteWithResults, results.count(results.count)")
       println(results)
       // still cannot get post id from photo upload
    }
    func sharer(sharer: FBSDKSharing!, didFailWithError error: NSError!) {
       println("sharer NSError")
       println(error.description)
    }
    func sharerDidCancel(sharer: FBSDKSharing!) {
       println("sharerDidCancel")
    }
   

我将感谢您的帮助。

Answer 1

    let photo = FBSDKSharePhoto()
    photo.image = chosenImage
    photo.isUserGenerated = false
    let photoContent = FBSDKSharePhotoContent()
    photoContent.photos = [photo]
    let shareApiInstance = FBSDKShareAPI()
    shareApiInstance.message = "customized facebook content"
    shareApiInstance.shareContent = photoContent
    shareApiInstance.delegate = self
    shareApiInstance.share()

委托方法

func sharer（_ sharer： FBSDKSharing！， didCompleteWithResults results： [AnyHashable ： Any]！） {
打印（"代表已呼叫"）

    let resultsInfo = results as! [String : Any]
    print(resultsInfo["postId"] as! String)
}
func sharer(_ sharer: FBSDKSharing!, didFailWithError error: Error!) {
    print("sharer NSError")
    print(error.localizedDescription)
}
func sharerDidCancel(_ sharer: FBSDKSharing!) {
    print("sharerDidCancel")
}

使用上述解决方法，您可以访问 postId。
