How to setup the Titanium+ Barcode module

I downloaded the barcode module, copied the folder into my projects root directory, added the <module version="1.0">ti.barcode</module> to tiapp.xml, and copied the example into the app.js file.

When I run the iPhone simulator and press the "Scan QR Code" button, nothing happens and I get this error in the Console:

[WARN] Exception in event callback. {

expressionBeginOffset = 462;

expressionCaretOffset = 478;

expressionEndOffset = 486;

line = 25;

message = "Result of expression 'Titanium.Barcode' [undefined] is not an object.";

name = TypeError;

sourceId = 199841424;

sourceURL = "file://localhost/Users/KG/Projects/Titanium%20Studio%20Workspace/QRtest/Resources/app.js";

}

Any help is appreciated...

The project module will be need copied to /Library/Application Support/Titanium/modules/iphone/ and not to project folder.

Thanks for the help. I copied the project module to /Library/Application Support/Titanium/modules/iphone/ and I'm still getting the same error. Here's my app.js code:

var barcode = require("ti.barcode");
 
// open a single window
var window = Ti.UI.createWindow({
  backgroundColor:'white'
});
window.open();
 
 
var button = Ti.UI.createButton({
    title:"Scan QR Code",
    width:150,
    height:40,
    top:20
});
 
window.add(button);
 
button.addEventListener('click',function()
{
    Titanium.Barcode.capture({
        success: function(event)
        {
            alert("success = "+event.result);
        },
        cancel: function(event)
        {
            alert("cancel");
        },
        error: function(event)
        {
            alert("Error. "+event.message);
        }
    });
});

I found the problem...

The sample code provided by the module 1.0 has this code at the top:

barcode = require("ti.barcode")

But later calls Titanium.barcode. Thus the above code needs to be:

Titanium.barcode = require("ti.barcode")

if you initialize it as `Titanium.barcode = ti.barcode = require("ti.barcode") you can then use either format to call the module methods.

I don't have experience on reading barcodes, by you can look into this link to find how to create them: EAN 128/ GS1 128 Barcode Add-In for ExcelYou may try it someday

i use ti.barcode module and i've this this error since one week. i don't undestand why. can you help me, please ?
