When I use setMetadataObjectTypes: to load the type of the scanning barcode, I would like to set severals types (code39, code128, etc...)

Question

I wrote this code for my app that uses the camera to scan barcodes:

[captureMetadataOutput setMetadataObjectTypes:[NSArray arrayWithObject:AVMetadataObjectTypeCode128Code/\*AVMetadataObjectTypeCode39Code\*/]];

I would like to know how it is possible to write the fact that the setMetadataObjectTypes can handle two types of barcode: the barcodes code39 and code128?

Answer 1

Okay, I think I finally found the good way to write it :

        [captureMetadataOutput 
         setMetadataObjectTypes:
         @[AVMetadataObjectTypeCode128Code, AVMetadataObjectTypeCode39Code]
];

or

    [captureMetadataOutput
     setMetadataObjectTypes:
     [NSArray arrayWithObjects:
      AVMetadataObjectTypeCode128Code, 
      AVMetadataObjectTypeCode39Code,
     nil]];

Hope it helps.
