Hi folks just a quick question, how do I read non-QR codes with zxing? I am setting the ZXingWidgetController to 1D mode, and am using a MultiFormatUPCEANReader however the barcodes just won't scan. Any suggestions?
However, someone did it: https://github.com/TheLevelUp/ZXingObjC
According to their site, only QR was ported to iPhone.

iphone: iPhone client + port to Objective C / C++ (QR code only)
As Lou says, zxing only support QR codes on iPhone.
A better bet is to use the alternative library ZBar, which supports EAN/UPC and is available here:

I know that the ZXing library for iOS reads only QR codes, but is there a version or port somewhere that reads 1d barcodes as well?
I can't seem to find one that is working currently.
The ZXing port for iOS does decode more than QR codes. For example, the Data Matrix port is up to date.
The 1D code support is not strong. You can turn 1D support on (look at the ScanTest code for an example how) and it will decode many 1D codes, but not as reliably as the Java port. (Use the code in svn or the git mirror if you do this; there's been a patch to fix a crash since the last release).
There's no port of ZXing that does better than this. No one has stepped up to help keep the 1D code in as good of shape in C++ as it is in Java.
It's not clear from the question if you're open to other open source libraries that might have better 1D suport. ZBar is the primary alternative.

Have fun
2 questions about the open-source, zxing barcode scanner.
A) Can I customise the design of the scan overlay/viewport on the iOS? Ie: change the square/overlay/cancel button etc.
If so, how, or is there documentation?
B) Can zxing scan 1D product barcodes on iOS yet? I can't seem to find documentation on this? Otherwise what are my options for scanning both QR codes and barcodes with the iOS?
Thank you.
Martin
Yes, you can make the source code do whatever you want, as it's open source. You can certainly customize what it looks like.
Yes, most of the 1D scanning code has been ported to C++ in this project. You can enable and use it.
Can anyone please tell me the way to do video chat in iphone?
I tried to search it on many website but in vain.
I found this link:
http://code.google.com/p/xmppframework/wiki/iPhone
I am not sure if this works for the video chat too?
Thanks,
Naveed
I don't have experience with XMPP, but I think you would have to add your own video solution on top of it. This is definitely not a straightforward task to accomplish - but this might be useful for you:
1) http://code.google.com/p/idoubs/ - open-source 3GPP IMS client for iOS
2) http://labs.adobe.com/technologies/cirrus/ - RTMFP protocol - works on iOS when compiled with Adobe AIR 2.6

I've started looking on the subject of Acoustic Fingerprint (http://en.wikipedia.org/wiki/Acoustic_fingerprint) for a pet project of mine for the iOS and I was wondering if there are:
Any opensource libraries or source code for the iOS that handle this?
Assuming I'm a veteran jack of all trades coder, is it very problematic to implement this myself if there is no open-source versions?
Will the Accelerate DSP library in iOS able to handle such a task?
Thanks
you may want to check out the EchoPrint CodeGen library by The Echo Nest. They even have a fully functional iOS code example.
You can find some additional links to open source audio fingerprinting related software in this MusicBrainz article, but AFAIK the EchoPrint library is the only one that has a license that is compatible with iOS apps.
Good Luck!
Not of my knowledge
No problem for a veteran, that won't be easy, but achievable.
Never looked into.
Even in java, this might be an interesting reading.
Before doing anything, especially if you intend to sell on AppStore, take care that these techniques/algorithms are patented. Read what happened to the above blog post writer.

NO
I also notice that you put the tag "voice recognition". Just to make sure voice recognition as nothing to do with audio identification/acoustic fingerprinting !!
i wanna ask that , is there any api to recognize image?
i need read data from image...can i read numbers which is printed on image..
It seems as though there is no built in function for OCR and this would have to be a custom aspect not found in foundation.
Good luck!
You can always download an open-sourced, external library (package) to do the OCR. GOCR is one example.
There are many OCR libraries available for reading text from an image. You can check my answer Mobile OCR Engine for iPhone app
and for reading numbers only check my answer How to read numbers only in an image
Hope it helps you.
