将视频保存到相机胶卷时出错？ [斯威夫特]

我有一个功能，我想用它来保存视频到相机胶卷。出于某种原因，在我停止录制后，什么都没有发生？它不会将它保存到相机胶卷或者让其他任何错误比将视频保存到相机胶卷时出错？ [斯威夫特]

Error Domain=NSCocoaErrorDomain Code=-1 "(null)"

这里是我的代码：

@IBAction func record(_ sender: UIButton) { 

    if recordingInProgress{ 
     output.stopRecording() 
     recordingLabel.textColor = UIColor.rgb(red: 173, green: 173, blue: 173) 
     PHPhotoLibrary.shared().performChanges({ 
      PHAssetChangeRequest.creationRequestForAssetFromVideo(atFileURL: self.outputURL as URL) 
     }) { saved, error in 
      if saved { 
       let alertController = UIAlertController(title: "Your video was successfully saved", message: nil, preferredStyle: .alert) 
       let defaultAction = UIAlertAction(title: "OK", style: .default, handler: nil) 
       alertController.addAction(defaultAction) 
       self.present(alertController, animated: true, completion: nil) 
      } 
     } 
    } 


    else{ 
     let documentsPath = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)[0] as NSString 
     let outputPath = "\(documentsPath)/output.mov" 
     outputURL = NSURL(fileURLWithPath: outputPath) 
     output.startRecording(toOutputFileURL: outputURL as URL!, recordingDelegate: self) 
     recordingLabel.textColor = UIColor.rgb(red: 250, green: 3, blue: 33) 
    } 

    recordingInProgress = !recordingInProgress 


}

要调用stopRecording后立即访问视频文件。正如here中所述，您应该只尝试使用capture(_:didFinishRecordingToOutputFileAt:fromConnections:error:)委托回调中的URL，因为录制需要在您要求停止对该文件的任何写入之前完成写入。

你会想你的照片库呼叫转移到该委托方法：

func capture(_ captureOutput: AVCaptureFileOutput!, didFinishRecordingToOutputFileAt outputFileURL: URL!, fromConnections connections: [Any]!, error: Error!) { 
    // PHPhotoLibrary.shared().performChanges... 
}
