Improve the Performance of BarcodeScanner

Using a template file is the quickest way to improve the performance of BarcodeScanner. A template file is a JSON file (or JSON string) that includes a series of algorithm parameter settings. Contact us to get a customized template for your scanner.

1. Add a Templates folder to the assets folder of your project at src\main\assets\Templates. Put your JSON file in the Templates folder. Here we use a ReadQRCode.json file as an example.

   

2. Specify the template file via property templateFile

   • Objective-C
   • Swift

   1. DSBarcodeScannerConfig *config = [[DSBarcodeScannerConfig alloc] init];
      config.templateFile = @"ReadQRCodes.json";
      

   2. let config = BarcodeScannerConfig()
      config.templateFile = "ReadQRCodes.json"
