-
-Use the `setScanningMode` method to switch between single-barcode and multi-barcode scanning modes.

-- `SM_SINGLE`: (Default) Single-barcode scanning mode.

-```swift

-
-### Configure the Auto-Stop Conditions
-
-For multi-barcode scanning, there are two automatic stop conditions:
-
-- The number of successfully decoded barcodes reaches the `expectedBarcodesCount`.
-- There are no new decoding results for N consecutive frames. The value of N can be set using `setMaxConsecutiveStableFramesToExit`.
-
-For example, apply the following settings:

-```objc
-DSBarcodeScannerConfig *config = [[DSBarcodeScannerConfig alloc] init];
-config.scanningMode = DSScanningModeMultiple;
-config.expectedBarcodesCount = 10;
-config.maxConsecutiveStableFramesToExit = 15;
-```
-2. 
-```swift
-let config = BarcodeScannerConfig()
-config.scanningMode = .multiple
-config.expectedBarcodesCount = 10
-config.maxConsecutiveStableFramesToExit = 15
-```
-
-If at least 10 barcodes are decoded, scanning stops. Otherwise, scanning continues for up to 15 consecutive stable frames. If no new decoding results are found within those 15 frames, scanning stops.

-## Comparisons
-
-If you are looking for a solution to scan large batches of barcodes, refer to [`BatchBarcodeScanner`](https://www.dynamsoft.com/use-cases/batch-barcode-scanning/){:target="_blank"}. `BatchBarcodeScanner` is much more capable of large-volume barcode scanning and provides a highly interactive UI for previewing, editing, saving, reusing, and sharing results.
