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/

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

See this Link
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 new to ios development .
can anybody pls tell me . is it possible to use Zxing lib for scanning bar/qr-code on iPhone for a webapp(HTML5/javascript) ?
i mean my webapp needs to use Zxing , Is it possible ?
Barcode scanning requires use of the camera on your phone, this device is not available from a webapp and therefore you cannot scan barcodes from the webapp, regardless of the library you would like to use.
Also, I dont think you can use C, C++, Objective C libraries from your javascript/html5 these libs would have to be on the phone where your code cannot get to it, and your browser most certainly cant run it.
One alternative would be PhoneGap, I am not too familiar with it, but it is an iOS (and or Android) shell around a webapp that runs as a native app. You could probably get camera support in there and maybe use the Zxing lib. You would have to look into that, but then you dont 'really' have a webapp anymore either.
EDIT: For phoneGap and Zxing see also: how to scan barcode using phonegap
These days you can get it working with the HTML5 Camera API and this little beauty; https://github.com/LazarSoft
enjoy.
I am newbie to iPhone application. But recently I saw a post asking for Barcode Reader for 3G iPhones. And people(including me) have referred to zxing which works on 3GS or later and if you want to make an appication for 3G then better you buy it from QuickMark or RedLaser to get 3g scanning.
So I planned something and need several information from you all
There are lots available on appStore. One of them is pic2shop(Which is a free application).
But what I want to know is:
What exactly is it done to recognize the barcode and generate code?
Is there any website or link to which when image of barcode is send will respond with the code generated or any API which does the same i.e. Taking picture and generating code.
And Secondly From Where does we get the information about the produce related to that barcode code.
Hi we recently had a product which required bar code scanning functionality, in the end after evaluating a lot options we went with zBar but it does not work on iPhone 3G it requires 3GS or above.
zBar is an open source SDK you can download it from sourceforge.
What we're doing right now is scanning bar codes using the zbar SDK & then calling upcdatabase.com API through xml-rpc to get the information about the product back.
And its working pretty well.
If you do not want to pay redlaser or others for SDK I would recommend using this approach. But of-course the downside is iphone 3G is not supported which I think does not represent many devices & also recently Apple has also dropped its support for its upgrades as iPhone 3G users will not be able to upgrade to iOS 4.3.
I actually own a 3G iphone & its very slow on iOS version 4.0 .
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
I'm using win7.
and i have website which i want to test it with iPhone browser environment.
which it's use most flash (jISFR).
this is the website i talking for,
http://www.hamuranalodge.com/
may you can see menu navigation is using flash jSIFR, which it's seems not work in iPhone, and want to fix it. of course i need iphone Testing for it.
Is there somebody know how i can test it with iphone browser?
may there is a software can do it?
or a website give service like that?
Thanks
Not a perfect solution but you might be able to test it on the Android browser instead. The SDK runs on all major OSs and is free to download and install. Just make sure that flash support is turned off. I'm pretty sure iPhone and Android both use WebKit so you should get similar behaviour on both.
You could use the iPhone simulator if you have access to a Mac.
There are sites like this:
http://www.testiphone.com/
but this one doesn't work very well, at least not for this particular request. Go there and point it at www.worldsbk.com - it renders the Flash block on the top right hand side just fine on my desktop computer (Firefox3 Mac OS X), but have a look here:

to see a screen grab of that page from my iPhone... Note the big grey block where the flash bit should be...
