Code Snippet

• Objective-C
• Swift

1. [DCEFeedback vibrate];
   // For example, if `vibrate` is called in the TextResultCallback of DBR, the device will trigger a vibration each time when barcode result is detected.
   - (void)textResultCallback:(NSInteger)frameId imageData:(iImageData *)imageData results:(NSArray<iTextResult *> *)results{
      [DCEFeedback vibrate];
   }
   

2. DCEFeedback.vibrate
   // For example, if `vibrate` is called in the TextResultCallback of DBR, the device will trigger a vibration each time when barcode result is detected.
   func textResultCallback(_ frameId: Int, imageData: iImageData, results: [iTextResult]?) {
      DCEFeedback.beep()
   }
   

beep

Trigger a beep when the method is called.

+ (void)beep;

1. [DCEFeedback beep];
   // For example, if `beep` is called in the TextResultCallback of DBR, the device will trigger a beep each time when barcode result is detected.
   - (void)textResultCallback:(NSInteger)frameId imageData:(iImageData *)imageData results:(NSArray<iTextResult *> *)results{
      [DCEFeedback beep];
   }
   

2. DCEFeedback.beep()
   // For example, if `beep` is called in the TextResultCallback of DBR, the device will trigger a beep each time when barcode result is detected.
   func textResultCallback(_ frameId: Int, imageData: iImageData, results: [iTextResult]?) {
      DCEFeedback.beep()
   }
