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 have an app that I built in html and javascript that i would like to test on an iphone. I have a apple developers license. How can I get it from my windows computer to an iphone?
In fact there is a way. Please take a look at this step-by-step guide for that process.And also you can take a look at this question on programmers.stackexchange.com
You need to buy a Mac... no other way around this :(
To build anything development wise for iPhone or iOS in general, must have a Mac.
However, if it is something you need to test that is html and js like you mentioned. Have a look at this plug in for google chrome.
I used this before to develop for multi platform web app. It also simulates accelerometer and gps too.
google plug in Ripple Emulator
I know a lot of similar questions have been asked, but my case is a little different.
I have a windows machine on which I want to do the development. I can borrow my friend's mac for signing/publishing to store or other things.
Is it possible to do this? Can I create a "Dynamic Web App Project" in eclipse, do the coding and finally use a MAC to finish it? My app is 100% offline app.
Where can I find the directory structure for the HTML/CSS files?
How can I achieve the iphone look and feel of buttons and other UI?
I know that many people have done this but I cant find any tutorial. Please point me to one if you know about it.
Thanks in advance.
Sounds like this would be a great job for phone gap.
http://phonegap.com/
They provide wrapping software to make your web application run natively on the phone.
It sounds to me like you should look at phonegap for the coding.
For getting your buttons, backgrounds, icons and such to look and feel more like native iOS apps, take a look at this list of graphics for iOS. Most are free. There are .zip files with pre cut images, and a number of .psd files for you to choose from. If you are not using xCode or Titanium to build the apps, these are a nice way of getting that native look and feel.
I'm must build the same application for android and iphone.
I tryed rhodes, that is great, but some native ui features are missing...
I would like to know, is there a strategy, sdk, framework, or something for building native applications for android and iphone that somehow reduce the rework?
Or any suggestion of other framework, like rhodes...
Thanks
Phone Gap is the place for you. You should have a look at this http://www.phonegap.com/about
Appcelerator Titanium
http://www.appcelerator.com/products/titanium-mobile-application-development/
Documentation, Documentation, Documentation!
Have a well written PDR and stick to it.
there is another approach which is to use a tool that generates both simultaneously like: phonegap or corona SDK.
Design for some level of resolution independence. Try to code as much as you appropriately can in HTML rather than native controls. And wrap common API calls so you have 1 method to change rather than 100 different calls all over the place.
You could consider using monotouch and monodroid.

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.
What I want to do is to make an iPhone application for my website similar to the photofunia. The users will be able to select an effect from a list, and then upload their own photo. Then the result will be shown in the browser where the user can save the image and/or publish to website like facebook, etc.
What software can I use to do that? Phonegap, appcelerator, etc? Can some of these help?
Thanks.
First of all, you may be able to make an iPhone app using Adobe Flash and the Adobe Packager for iPhone.
The other option is to get a Mac and Learn Objective-C.
There is no "easy" solution here.
Create a webservice for your website and try to use that in your iPhone Application
Of course I know there is no "easy" solution, but I'm almost sure there are other options for making iphone apps, instead of using Objective-C.
I only don't know the name of the tools.
Flash doesn't works. Adobe Air currently doesn't offer a way to access the camera roll on the ios.
