Question
I'm using worklight for my mobile app project. My problem is, I dont know where I can find these files (zxing-all-in-one.cpp and zxing-all-in-one.h) for barcode scanner integration with worklight in Xcode5. Since ChildBrowser plugin alreade deprecated, check this out. https://github.com/phonegap/phonegap-plugins/tree/master/iOS/BarcodeScanner
I read through this blog regarding to zxing integration with worklight.
