CIDetector是否适用于其他条形码类型

Question

I am looking at CIDetectorTypeQRCode. How can I detect other types of barcodes? I can read other barcode types via AVMetadataObjectType, however I want to do the same with CIDetector. I am trying to achieve real time highlighting of the barcode.

Trying for a sort of zoom in effect before my AVCaptureMetadataOutputObjectsDelegate achieves a full lock and read of the code.

Answer 1

CIDetector has only following types to detect, So we can't use it to detect another type of barcodes.

• CIDetectorTypeFace
• CIDetectorTypeRectange
• CIDetectorTypeQRCode
• CIDetectorTypeText

But since iOS 11 has introduced a new set of Vision API's. Now it is possible to read barcodes from an image.

if you are targeting >iOS 11, you can use VNDetectBarcodesRequest to read barcode results.
