Addes 0(zero) while scanning a perticular barcode

[ritesh124]

The correct Barcode is 070177137069 but using RSBarcode it shows 0070177137069.

Okay So after in details came to know this solution (http://stackoverflow.com/questions/22767584/ios7-barcode-scanner-api-adds-a-zero-to-upca-barcode-format)

Apple just convert every UPC-A barcode to EAN13 just by adding a leading zero.

The solution is to verify if the barcode is EAN13 and if the string result have a leading zero is safe to remove it and obtain a UPC-A barcode.

but i don't know where to add the code. Thanks in Advance

Solved By adding below code

let trimmedCode = readableCode.stringValue.stringByTrimmingCharactersInSet(NSCharacterSet.whitespaceCharacterSet())

            print("trimmedCode: \(trimmedCode)\n\n")

            // EAN or UPC?
            // Check for added "0" at beginning of code.

            let trimmedCodeString = "\(trimmedCode)"
            var trimmedCodeNoZero: String

            print("trimmedCode: \(trimmedCode)\n\n")

            if trimmedCodeString.hasPrefix("0") && trimmedCodeString.characters.count > 1 {
                trimmedCodeNoZero = String(trimmedCodeString.characters.dropFirst())

                print(" if trimmedCodeNoZero has 0:   \(trimmedCodeNoZero)\n\n")

                // Send the doctored UPC to DataService.searchAPI()

            } else {

                // Send the doctored EAN to DataService.searchAPI()
                print(" else trimmedCodeString: \(trimmedCodeString)\n\n")

            }
