swift - 视频未保存在解析中

Question

输出显示:

- Snapshotting a view that has not been rendered results in an empty snapshot. Ensure your view has been rendered at least once before snapshotting or snapshot after screen updates.
- Save successful

但是当我进入解析后端时，没有任何内容被保存。

@IBAction func recordAction(sender: AnyObject) {

    if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.Camera){
    print("Camera Available")

    let imagePicker = UIImagePickerController()

        imagePicker.delegate = self
        imagePicker.sourceType = .Camera
        imagePicker.mediaTypes = [kUTTypeMovie as String]
        imagePicker.videoMaximumDuration = 180 // Perhaps reduce 180 to 120
        imagePicker.videoQuality = UIImagePickerControllerQualityType.TypeMedium
        imagePicker.allowsEditing = false

        imagePicker.showsCameraControls = true

        self.presentViewController(imagePicker, animated: true, completion: nil)
    }
        else {
            print("Camera Unavailable")
        }
}

func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {

    let Video = PFObject(className:"Video")
    Video["user"] = PFUser.currentUser()

   let tempImage = info[UIImagePickerControllerMediaURL] as! NSURL!
   _ = tempImage.relativePath

    let videoData = NSData(contentsOfFile:tempImage.relativePath!)

    let videoFile:PFFile = PFFile(name:"consent.mp4", data:videoData!)!
    Video["videoFile"] = videoFile
    self.dismissViewControllerAnimated(true, completion: nil)
    videoFile.saveInBackgroundWithBlock({ (succeeded: Bool, error: NSError?) -> Void in
        // Handle success or failure here ...
        if succeeded {
            print("Save successful")
        } else {
            print("Save unsuccessful: \(error?.userInfo)")
        }

        }, progressBlock: { (amountDone: Int32) -> Void in

    })
}

我明白了。我的数据库中有一个额外的列，但在应用程序代码中没有说明。当我删除它时，数据发送成功。
