I want to make an iPhone application to read Barcode(QRCode) using Rhodes.
I tried to download and build "rhodes-sample-api",
but, "uninitialized constant BarcodeRecognizerController :: Barcode" error will appear.

By the way, it is an error and can be invoked in iphone simulator, when you start with actual iphone.

development environment:

[RhoMobile Suite]
Rhodes3.4.2, RhoElements2.1.1(which has not yet obtained a license)

Ruby1.9.3
xcode4.5
ios5.1

I'm in trouble I do not know the cause.
Can you answer someone?
