使用自定义相机拍照 iOS 11.0 Swift 4. 更新错误

我的应用程序中有一个自定义摄像头，它工作正常，但在新的更新后，我遇到了以下错误:

"jpegPhotoDataRepresentation(forJPEGSampleBuffer:PreviewPhotosSampleBuffer:)"在iOS 11.0中被弃用:改为使用-[AVCapturePhoto fileDataRepresentation].

这是我得到错误的地方:

    guard let imageData =
        AVCapturePhotoOutput.jpegPhotoDataRepresentation(forJPEGSampleBuffer: photoSampleBuffer, previewPhotoSampleBuffer: previewPhotoSampleBuffer) else {
            return
    }

这是我的全部功能(如果需要):

//Take pic function
func photoOutput(_ captureOutput: AVCapturePhotoOutput,
                 didFinishProcessingPhoto photoSampleBuffer: CMSampleBuffer?,
                 previewPhoto previewPhotoSampleBuffer: CMSampleBuffer?,
                 resolvedSettings: AVCaptureResolvedPhotoSettings,
                 bracketSettings: AVCaptureBracketedStillImageSettings?,
                 error: Error?) {


    // Make sure we get some photo sample buffer
    guard error == nil,
        let photoSampleBuffer = photoSampleBuffer else {
            print("Error capturing photo: \(String(describing: error))")
            return
    }
    // Convert photo same buffer to a jpeg image data by using // AVCapturePhotoOutput
    guard let imageData =
        AVCapturePhotoOutput.jpegPhotoDataRepresentation(forJPEGSampleBuffer: photoSampleBuffer, previewPhotoSampleBuffer: previewPhotoSampleBuffer) else {
            return
    }

    let dataProvider = CGDataProvider(data: imageData as CFData)

    let cgImageRef = CGImage(jpegDataProviderSource: dataProvider!, decode: nil, shouldInterpolate: true, intent: CGColorRenderingIntent.absoluteColorimetric)


    let image = UIImage(cgImage: cgImageRef!, scale: 1.0, orientation: UIImageOrientation.right)

    self.tempImageView.image = image

}

我的目标是:What should I use instead to make it work?

非常感谢.
