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
Zbar SDK is not working in iOS6
other source =

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.

Thanks in Advance
I have used ZBar SDK In my app..it is pretty easy to use and is also customizable.

I am new in iphone development and we have to integrate the QR code reader in my apps, i have no idea about that some one please guide me how can i start. Give me some sample code or any tutorials links for that. Any help is highly appreciated.
There is a great library to do such project. Take a look at zxing. There is an obj-c version.
try out zbarSDK! it worked well for me, http://zbar.sourceforge.net/iphone/sdkdoc/
Here is the zxing (zebra crossing) google library. It can get you started. Hope that helps!
Can I really do that with the phone? Perhaps I would have to call any of the native API's, but I am not really sure whether and what is possible. I am pretty sure that the camera is accessible, so at the worst case I could send the picture to the server, decode the QR code on the server, and get the results on the phone, right ?
There's a QR code reading class here: http://www.libspark.org/wiki/QRCodeReader/en and some instructions on how to use it: http://blog.jactionscripters.com/2009/05/23/introduction-of-qr-code-reader-library/
While I've never done it, iOS does support the camera as far as I know so it should work just fine. The code is pretty similar to using a webcam.
And here's a library which claims to be improved: http://www.kasperkamperman.com/blog/flash-qrcode-reader-as3/
If you are working on a iOS (iPhone or iPad) project, i recommend you qr-zbar-ane native extension. You can find download links and sample code at : http://www.nativext.com/ane-by-os/ios/qr-reader-native-extension/
We're creating an iOS app that basically scans badges at events and collects contact info. We're looking for an iOS library that can read not only the number of the barcode, but also any additional information that's included (contact info). Does anyone have any library suggestions or will this have to be a custom library? Thanks in advance!
Updated:
Use AVCaptureMetaDataOutput in AVFoundation which works with minimum deployment target iOS 7.
Previous Answer:
Have been using ZBar SDK in most of our projects. Picks up barcode and scans very fast, easy to customize focus area from SDK. Tested on iPhone 3GS, iPhone4/4S, iPhone 5 and iPad
https://codeload.github.com/cgreening/BarCodeExample/zip/master
iOS7 has built in functionality scanning BarCodes not sepearate sdk is required; if your deployment target is iOS7
Is your barcode format up to you, or do you have a predetermined symbology you have to work with?
There is this: http://shopsavvy.mobi/sdk/. Don't know why that wouldn't work for you, unless you object to the licensing terms.
Checkout ZXing ("Zebra Crossing") at http://code.google.com/p/zxing/
Reads almost every kind of barcodes and we used it with great success previously.
Use ZBAR its the best, we used it in our app www.infomq.com and its is really stable and scans reliably.
Basically you want to use PDF417 which is a stacked linear barcode symbol. Check out the pdf417 decode on Sourceforge.
Is it possible on an iPhone app to take a picture and extract an string from the picture? We'd like to make our app to look for a serial number on a database (very long number) without the user having to type it.
Is there any Cocoa/Objective-C API for this or any C/C++ library that can be used in an iPhone app?
Thanks in advance!
You can have a look at the tesseract-ocr project. It's not actually made to use on an iPhone but I believe others have made great use of it on the iPhone.
Here is a demo that makes use of the tesseract ocr engine.
I was looking for something similar and came across ABBYY's mobileOCR solution
I've not used it yet and have no idea how much it is but you should be able to integrate it into your app by all accounts.
I have this in my bookmarks: http://code.google.com/p/zxing/
It has iPhone, Android and Java code to deal with image capture and bar codes.
I haven't test it yet.
Here's another implementation of Tesseract on the iPhone: http://robertcarlsen.net/dev/pocket-ocr
Tesseract-OCR now has iOS version:Tesseract-OCR-iOS
