Hi!

I'm using Tibar in an iPhone module. I'm actually testing your project (and I 
love it: very efficient!).
But recently, I had an issue.
I have a simple code as in your example:

button.addEventListener('click', function(){
    TiBar.scan({
        // simple configuration for iPhone simulator
        configure: {
        classType: "ZBarReaderViewController"
        ,sourceType: "Camera" // Library(C), Camera(VC), Album(C)
        //,cameraMode: "Default" // Default, Sampling, Sequence
        ,config:{
            "showsCameraControls":false // (VC) true
            ,"showsZBarControls":true
            ,"tracksSymbols":true
            ,"enableCache":true
            ,"showsHelpOnFail":true
            ,"takesPicture":true // true
        },symbol:{
            "QR-Code":true,
            "CODE-128":true,
            "CODE-39":true,
            "I25":true,
            "DataBar":true,
            "DataBar-Exp":true,
            "EAN-13":true,
            "EAN-8":true,
            "UPC-A":true,
            "UPC-E":true,
            //"ISBN-13":true,
            //"ISBN-10":true,
            "PDF417":true
        }
    },
    success:function(data){
        Ti.API.info('TiBar success callback!');
        if(data && data.barcode){
            Ti.UI.createAlertDialog({
                title: "Scan result",
                message: "Barcode: " + data.barcode + " Symbology:" + data.symbology
            }).show();
        }
    },
    cancel:function(){
        Ti.API.info('TiBar cancel callback!');
    },
    error:function(){
        Ti.API.info('TiBar error callback!');
    }
    });        
});

When i load my app on my iPhone, I have the normal page with the 'Scan barcode' 
button. But when I click on it, it freezes and I have this log:

As you can see, it searches a file into : /Users/spadix/...
And spadix seems to be a developper of Zbar (http://zbar.sourceforge.net/)

Do you know this issue?

For info, I'm using an iPhone 3GS, with iOs 4.1.2. I compile for iOS 4.1 (and 
4.2, it's the same issue).

hi,

your problem is here:

http://sourceforge.net/projects/zbar/forums/forum/1072195/topic/3925029/index/pa
ge/2

the sample app hangs, you can build from scratch  is you compile the module 
with Zbar SDK beta 1.1...

Hi there. neither the 0.4.2 fixes the "Assertion failure in

any ideas?

But the scan works anyway... Am I wrong?

Original comment by rmnsal...@gmail.com on 15 Feb 2011 at 9:40

GoogleCodeExporter commented 9 years ago 
no, I don't even get the camera opened. if the scan would work, it would be ok 
for me.

i'm testing on iPhone 3GS.

With the "normal" ZBarReaderController mode, everything works fine.

It works for me. I'm testing on iPhone 3GS with iOS 4.2. And I compile my 
application for iOS 4.1
My params should be the same than upper:

I'm at work now, but I will have a try this evening and report my luck/fail.

Original comment by sebastia...@gmail.com on 16 Feb 2011 at 3:14

GoogleCodeExporter commented 9 years ago 
ok, I tried to compile for iOS 4.2 with your configuration. That fails.

do I have achance to get the 4.1 SDK or compile it with 4.1?

Original comment by sebastia...@gmail.com on 17 Feb 2011 at 10:57

GoogleCodeExporter commented 9 years ago 
You don't need the sdk 4.1 to compile for 4.1.
You just have to choose before the compilation.

In Titanium, just select the SDK in the field 'Select SDK version' (cf. 
screenshot).
In Xcode: open your xcode project under 
'[projectName]/build/iphone/[projectName].xcodeproj'. Then, click on you 
project name (1), then 'build' tab (2), 'All Configurations' (3) and then : 
'iOS Deployment Target (4)

But if it doesn't work with 4.2, I'm afraid it won't with 4.1...

thanks for that. 

ok, so I tried several ways. Compiled in 4.1 or 4.2. 
I did the changes in my project configuration. the result is the same as it was.

I don't understand why it works in your project and neither in mine.

And try to put 'takesPicture' to 0.
Because as your can see in your log, it's 'setTakedPicture' which has a problem.

done, next message: *** Assertion failure in -[ZBarReaderViewController

cameraMode is set with "Default", or isn't it? I took your config

Original comment by sebastia...@gmail.com on 17 Feb 2011 at 1:43

GoogleCodeExporter commented 9 years ago 
In my config, it's written:

cameraMode: "Default", // Default, Sampling, Sequence

Maybe you can try with : 'Sequence' and 'Sampling'...

all 3 possibilities (Default, Sampling, Sequence) fails in

There is another parameter you can modify, but it won't be as cool:

classType: "ZBarReaderController"

If I have well understood, with this parameter you take a photo, and the 
barcode is not detected by the video camera.

that works. and it's totally uncool. that isnt, what i'm looking for. 

ZBarReaderViewController would be nice to work with

anybody any idea, how to get the ZBarReaderViewController instead of

Just a thought.
In your tiapp.xml, have you precised:

<modules>
    <module version="0.4.2">tibar</module>
</modules>

Original comment by rmnsal...@gmail.com on 22 Feb 2011 at 11:30

GoogleCodeExporter commented 9 years ago 
yes, exactly that version

    <module version="0.4.2">tibar</module>

If your project is not too secret, I can test in my 3GS if you want. Thus, we 
will know if it comes from your code or somewhere else.

Tested on iphone 4G with iOS 4.3. Using the 1.5.2 SDK from the continuos 
appcelerator builds, everything works great. Make sure you follow all steps to 
setup the modues, include frameworks, etc etc. Try the newest 4.3 SDK maybe 
that will help
