How to Upgrade

From Version 8.0 to 8.x

You need to replace the old DynamsoftBarcodeReader.framework file with the one in the latest version. Download the latest version here. You could also download it via terminal pod install 'DynamsoftBarcodeReader'. For v8.9 or higher v8.x versions, you have to include DynamsoftCameraEnhancer.framework as well.

From Version 7.x to 8.x

You need to replace the old DynamsoftBarcodeReader.framework file with the one in the latest version. Download the latest version here.

Your previous SDK license for version 7.x is not compatible with version 8.x. Please contact us to upgrade your license.

In v8.0, we introduced a new license tracking mechanism, License 2.0.

If you wish to use License 2.0, please refer to [this article]({{ site.license_activation }}set-full-license.html) to set the license.

After you upgraded your license to version 8.x:

• If you were using initWithLicense, please replace the old license with the newly generated one.

• If you were using initWithLicenseFromServer to connect to the Dynamsoft server for license verification, then no need to change the license key. But please make sure the device has an Internet connection.

From Version 6.x to 8.x

We made some structural updates in the new version. To upgrade from 6.x to 8.x, we recommend you to review our sample code and re-write the barcode scanning module.
