iOS Mobile App, Flex 4.6, QR-Code reader...

Has anyone ever been able to actually get an iOS QR-Code reader app to work correctly?  I've looked at literally DOZENS of blog-posts -- they're all based on two posts (http://www.remotesynthesis.com/post.cfm/adding-a-qr-code-reader-in-fle x-on-android and http://www.libspark.org/wiki/QRCodeReader/en) so they're all pretty much the same -- and NONE of them seem to work on a 5th generation iPod Touch with iOS 5.1 and Flex 4.6 (the examples are all Android devices and Flex 4.5.1).  I've tried every last permutation of each of those two posts that I've found, and read every comment on all of them, and I can't get any of them to work at all on this stupid iPod Touch...

 

So -- has ANYONE written a FUNCTIONAL qr-code reader for an iOS device using Flex 4.6?

 

Any help you can give would be appreciated...

 

Thanks,

    Hi,

     

    Yes, I've got QR code reading working on iOS using Flash Builder 4.6. It works fine for me on my iPhone 4, and iPad 3. What problems are you having specifically?

    I'm using ZXing and it isn't slow for me (certainly not 5 seconds to process). I haven't tried libspark. Let me put together an example based on an app I've written (haven't released it for iOS yet ;-).

    I've posted an example .fxp project based on the remotesynth.com example. You can download the Flash Builder 4.6 file here --> http://www.tutorialsbyibrent.com/assets/QRReader.fxp

     

    One thing I didn't try in order to speed up this example is to comment out the System.gc(); calls to see if that helps.

    Hmmmm, well I don't have an iPod Touch to compare with, but I know that

    the code works on my iPhone 4 and iPad 3. Sometimes I have to scan the

    code a few times, moving the camera slightly to fit the code into the

    video area. Blurry codes won't decode well either. Have you downloaded

    other QR apps and tested those on your device? Maybe it is the camera

    that's the problem.

    Lawrence:

    Any look doing thiw with LibSpark?

     

    I'm trying to do the same thing for mobile, have iBr3nt's code working, but, it takes a lot of tries to get the QR to be recognized.

     

    Thanks,

    David

    The project (http://www.tutorialsbyibrent.com/assets/QRReader.fxp) has been imported and compiled in a Flex 4.6 builder and compile perfect. Then it has been tested in the emoulator and works!!!! and instaled un a Android 2.3.6 and works perfecty (the camera and the qr recognition).

     

    Thanks!!!!! Ibrent
