ios - 通过 ios 应用程序将照片分享到 Facebook 后无法获取结果帖子 ID(Swift 和 FBSDK4.0.1)

Question

我正在编写一个 iOS 应用程序来进行照片共享。

使用技术 Swift 和 FBSDK 4.0.1

通过FBSDKSharePhotoContent()发现图片分享 无法从方法 didCompleteWithResults 内的 FBSDKSharingDelegate 中的结果对象取回任何帖子 ID。
结果对象包含空行:

[:]

但是，通过FBSDKShareLinkContent()分享的URL 可以从结果对象中取回帖子 ID。 类似的东西:

[postId: 10000844250000_146108069750000]

我的部分核心代码:

1. 图像选取器 Controller (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)
   }
   

1. 选择照片后，点击自定义分享按钮

    @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)
   }
   

2. Facebook 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")
   
    }
   

我会感谢你的帮助。

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(delegate)方法

func sharer(_ sharer: FBSDKSharing!, didCompleteWithResults 结果: [AnyHashable : Any]!) {
print("代表叫到")

    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")
}

通过上述解决方法，您可以访问 postId。
