How to use iPhone Camera as Bar Code Scanner?
hi all How do we do programmatic reading of a barcode that is captured using a mobile phone camera? For example, how do that using iPhone? Do we need separate hardware to read bar code or can we do image manipulation? help me to solve the problem in iphone.
give the guide for how to use outside api to read the bar code as programmatic in iphone.
Look At the following links
RedLaser
Softek Barcode Reader SDK
ZBar
There are open source libraries available which does this. Y can't use the same?
"Zbar" framework is one such.
I am unable to comment on your question, but there is a possible duplicate here, How to use iPhone Camera as Bar Code Scanner?
Also, you might do well to use a third party library. If you are looking to learn, then have a look around google :) The ZBar library, for example, is hosted on source forge.

Enhanced iOS barcode scanner library?
(6 answers)
Closed 9 years ago.
I was wondering what type of technology is used in the apps that can scan a barcode and output data that that barcode represents. What type of programming would the app use to access the camera and be able to read a certain barcode?
if type of smartphone matters then specifically IOS.
You can use this framework in your code to have a barcode reader in your IOS app...
In iOS 7, you can use the AVFoundation framework to scan barcodes natively. Here's a tutorial to get you started http://www.infragistics.com/community/blogs/torrey-betts/archive/2013/10/10/scanning-barcodes-with-ios-7-objective-c.aspx
If you need to support older versions of iOS, the ZBar library, which emreoktem has linked in his answer, is probably your best bet.
i think here is the some demo code and also demo of app here

I want to develop an application for QR code reader.So i need to know what are the frameworks that i need to implement for this application.
I had some success integrating zbar into an OS X app.
http://zbar.sourceforge.net/index.html
It also has support for iOS and a sample app you can use it with.
This is the only open-source project I know of that has anything to do with QR codes on iOS, but it looks like it should work for you: Zebra Crossing ( http://code.google.com/p/zxing/ ).
You can find a similar question here :

How can I be able to implement read/scan bar code in my iphone application.
I also would like to know how to implement it into the iphone application.
If possible suggest me the links and example source code and applications to understand how it works.
I want to generate the barcode dynamically...is i possible...if yes then suggest me how it can be generated..?
To read barcodes: Zbar, ZXing, Redlaser

If you look up their websites you can download their sample application as well.
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

How do I launch iBooks e-reader programmatically on iPad?
I'm creating an application for a client. The iPad will be pre-loaded with a ebook that we will be creating ourselves. This ebook will not be available in the bookstore, but will be preloaded via itunes.
Is it possible to open the iBooks application from my application, via some URL schema?
Is it then possible to link directly to our pre-loaded book from our application?
Any info would be appreciated.
Cheers

iBooks registers the itms-books: and itms-bookss: URL schemes. One would hope that passing an ISBN as the url would launch the correct book in the store, but I am not sure if it does.
It seems as if there's a solution for native apps here: http://andycodes.tumblr.com/post/738375724/ios4-sdk-opening-pdfs-in-ibooks
We have a similar issue, and working on implementing solution above.
We currently have hacky version that linked from shared dropbox folder to open in browser, and then asked user to select "Open in iBooks" (as described here): http://support.apple.com/kb/ht4227
Does the trick, and prevents us from having to preload on 200 iPads but lots of room for user error.
Here's a list of url schemes in iPhone OS. Looks like you're out of luck of iBooks.
You could start a mini-webserver with your application and open a URI like itms-books://localhost:1234/my.epub
In short, no. iBooks won't be able to load anything that comes in your application's bundle.
