ZBAR sdk 未在 iPhone 4s (ios 5.1) 上检测到 QRCODES...？

Question

I have integrated the ZBAR sdk in my project and it is working fine for barcodes but it is not detecting the QRCodes. I am using the iPhone 4s and I don't have any other device.. is this a known issue..? I am using the ZBarReaderViewController...

Answer 1

Double check that the scanner is configure for reading QR codes. Check my example below:

ZBarImageScanner *scanner = reader.scanner;

[scanner setSymbology:ZBAR_QRCODE
               config:ZBAR_CFG_ENABLE
                   to:1];

Answer 2

This may be because of the data that you are encoding in QRCode. In Barcode it will be a number always, but in QR code code it is not like that. Try to store the data in a string and log the string.

Answer 3

i have use zbar Api for the UPC barcode scanning and its working very fine follow the below tutorial in ios 5.please refer it and try it i have tested in devices its working well.
