SDCDataCaptureContextFrameListener

@protocol SDCDataCaptureContextFrameListener <NSObject>

Added in version 6.0.0

Protocol for observing/listening to frame processing related events of a data capture context.

To observe changes of the data capture context’s frame processing, one or more SDCDataCaptureContextFrameListener may be added. These listeners provide hooks into different parts of the data capture context.

Frame processing only happens if at least one SDCDataCaptureMode is added.
