视觉扫描无法识别 iOS16 上的 GS1 条码特殊字符

我们正在使用Vision库扫描GS1条形码.

The library does not recognize the special character "GS" in the iOS 16 versions.个

"GS"--&gt；组分隔符(ASCII 29)

在旧版本中，我们不会遇到这样的问题.例如，iOS 15.6或更低版本.我已经上传了下面的GS1条形码示例图片.

After scanning we should be getting: {GS}10BF50001A{GS}21003032{GS}1122012722VD020个

What we get instead on iOS 16 is: 10BF50001A210030321122012722VD020个

我还发布了一个关于如何使用库的示例代码.我们没有更改代码，该错误仅出现在iOS 16版本中.我们想知道是不是引入了窃听器.

func captureOutput(_ output: AVCaptureOutput, didOutput sampleBuffer: CMSampleBuffer, from connection: AVCaptureConnection) {
    guard let pixelBuffer = CMSampleBufferGetImageBuffer(sampleBuffer) else {
        return
    }

    let imageRequestHandler = VNImageRequestHandler(cvPixelBuffer: pixelBuffer, orientation: .right)

    do {
        try imageRequestHandler.perform([detectBarcodeRequest])
    } catch {
        logger.error(tag: TAG, "barcode error: \(error)")
    }
}

private lazy var detectBarcodeRequest = VNDetectBarcodesRequest { [weak self] request, error in
    guard error == nil else {
        self?.logger.error(tag: self?.TAG, "barcode error: \(error)")
        return
    }
    self?.processVNRequest(request)
}

private func processVNRequest(_ request: VNRequest) {
    guard let barcodes = request.results else {
        return
    }

    for barcode in barcodes {
        guard let potentialBarcode = barcode as? VNBarcodeObservation else {
            return
        }

        guard let payload = potentialBarcode.payloadStringValue else {
            return
        }

        prepareToNotifyDetectionEvent(payload)
    }
}

提前谢谢您.
