I have one application in which I want to scan QR code + bar codes on food packets for 1 store. I have tried ZBar reader for bar code scanning. It is working perfectly. Now I want to scan QR code also. For that I have searched and downloaded sample code. But all are not proper. Can anybody help?
If You want to read QRCode use Zbar sdk
try this
ZBarImageScanner *scanner = reader.scanner;
[scanner setSymbology:ZBAR_QRCODE
config:ZBAR_CFG_ENABLE
to:1];
Megha:Zbar SDK is best for bar code and QR Code Scanner
u have to try this link
https://github.com/a2n/zbar-iphone-example
i have also tried this in My Application and its working perfect.
There are 40 versions of QR code.
I am sure ZDBar SDK scans version 1 QRCode I have used it successfully.Check the documentation to verify the other supproted versions.
Have yo identified the version of QR codes you want to support ?
Cheers
i have used this http://zbar.sourceforge.net/iphone/sdkdoc/install.html in many of my applications to read qr codes,bar codes,UPC codes sucessfully

Is there a current iPhone QR library? Zebra Xing is pretty huge for the small app that I plan to make. ZBar has the wrong kind of license. Any suggestions would be well appreciated. All it has to do is recognize a QR code and interpret it, hopefully at a high frame rate. Thanks in advance.
You can also try shop savvy iphone sdk for read qr code : http://shopsavvy.mobi/sdk/
Zbar is the best. Easy to integrate and good documentation is there. See their site http://zbar.sourceforge.net/. And see their tutorial http://zbar.sourceforge.net/iphone/sdkdoc/tutorial.html.
Thanks
you can do using this :
ZBar = SDK
and
use this step which gives by this answer

This one looks good, we are using it: Esponce QR Reader - it is fast, nice looking, easy to use and it recognize all fields from contact cards correctly, also unicode chars.
i am working on an application where we need to scan QR codes for iPhone.
I am using zxing API for it. App is working great with iOS 6.0.1 but it's not working right with the latest release of iOS 6.0.2.
I am sending the scanned QR code to the server which gives me this response.
For example, if the QR code is 00012123456789000134,
iOS 6.0.1 version is giving me 00012123456789000134 as result but iOS 6.0.2 gives the result as 2100012123456789000134\u001D0111223344556677.
I don't know what is the problem. Is it due to the fixes in iOS 6.0.2 ????
Please help me out.
Thanx in advance.
Have you tried to scan with ZXing's own scan app from the app store, you need to check that out first to make sure that the problem is not the SDK nor the QR Code you are scanning.
If it is related to your code, review how you the result string is handled and moved to the output. it can be any of a few things, Zombies, incompatible types and moving between them, but mostly logic error. If you can post your codes, a lot more people will probably be able to help you. Also always the thing that ultimately helps is a lot of printfs.
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...
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];
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 .

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.
ZBAR sdk is normally used to read QRcode or barcode & convert it to user data. Can we use ZBAR API to create QRcode for iphone?
As far I know Zbar SDK can only be used to read.
Maybe this link will be of some help.

https://github.com/myang-git/QR-Code-Encoder-for-Objective-C worked well to generate QR Codes even with much content and UTF-8 characters (where some other generators I tried failed). The project is active and Apache 2.0 licensed.
i am using zxing for barcode reader into my iphone application .But it is working for QRCoder 2D barcodes .But for my app i need to scan 1D barcodes. So what should i change into my code ,
or else what should i have to do so that my app is able to scan 1D barcodes.
You can use redlaser sdk for the barcode scanning. Check this url:
http://redlaser.com/
This will be useful for the following barcodes
What about the ZBar - Library ?
http://zbar.sourceforge.net/iphone/index.html
http://code.google.com/p/zxing
It says below that the iphone port of the zxing project for android only has the QR section implemented. So zxing isnt the way to go if you are looking for 1d barcodes.

Why don't 1D codes work on iOS devices? An initial port of the Java code to C++ for 1D codes was done some time ago but has not been actively maintained. Results generated by this code are not comparable in quality or stability to the Java code.
Because of this, it is disabled by default in the iOS classes. Contributors interested in improving and maintaining this code are welcome. It's not particularly hard; the Java code is actively maintained and not very difficult to port. The need is for someone with sufficient interest/motivation.
