SDCIdCaptureOverlay
@interface SDCIdCaptureOverlay : NSObject <SDCDataCaptureOverlay>

Added in version 6.6.0

Overlay that guides the user through the SDCIdCapture process.

In order to display this overlay, add it to data capture view.

This overlay shows a viewfinder, automatically selected based on SDCIdCaptureSettings.supportedDocuments and SDCIdCaptureSettings.supportedSides, along with animations and textual hints, that allow the user to capture smoothly and avoid common pitfalls. It is designed to work out-of-the-box for a wide range of use-cases.

You can tweak the look of the viewfinder by setting idLayoutStyle and idLayoutLineStyle. Additionally you can configure the brush used to highlight localized, captured, or rejected documents.

You can translate the texts used by the viewfinder into various languages by adding adding string resources with the following ids to your app:

Resource id

Comment

scandit_id_capture_camera_too_far

Document cannot be captured, because the camera is too far.

scandit_id_capture_document_partially_visible

Document cannot be captured, because it’s only partially visible - either covered or not fully fitting the frame of the camera.

scandit_id_capture_show_document

Ask the user to show a document, front of card capture scenario or multiple document types selected.

scandit_id_capture_show_passport

Ask the user to show the passport.

scandit_id_capture_show_front_of_document

Ask the user to show the front side of a document in the front & back capture scenario.

scandit_id_capture_show_back_of_document

Ask the user to show the back side of a document in the front & back capture scenario.

scandit_id_capture_show_barcode_on_document

Ask the user to show the barcode on a document, either when a barcode type is selected or the back side of a document in the front & back capture scenario contains only a barcode.

scandit_id_capture_show_visa

Ask the user to show the visa.

The default texts can also be replaced with custom messages by calling setFrontSideTextHint: and setBackSideTextHint:. setFrontSideTextHint: replaces texts displayed asking the user for the front side of a document, in the front & back capture scenario, but also when only a single side or a part of a document is being captured. setBackSideTextHint: replaces texts displayed asking the user for the back side of the document in the front & back capture scenario. These methods take precedence over the texts set using string resources.
