AVFoundation,如何在captureStillImageAsynchronouslyFromConnection时关闭快门声音？

if #available(iOS 13.0, *) {
    photoOutput.isDualCameraDualPhotoDeliveryEnabled = false
}

let photoSettings = AVCapturePhotoSettings(format: [AVVideoCodecKey: AVVideoCodecType.jpeg])
photoSettings.isHighResolutionPhotoEnabled = true

photoOutput.capturePhoto(with: photoSettings, delegate: self)

func photoOutput(_ output: AVCapturePhotoOutput, didFinishProcessingPhoto photo: AVCapturePhoto, error: Error?) {
    guard let imageData = photo.fileDataRepresentation(),
          let image = UIImage(data: imageData) else {
        return
    }
    // 使用捕捉到的静态图像数据进行后续操作
}
