is there a way to read 1d barcodes using zxing for iPhone? The zxing's homepage says it can only be used for QR Codes but has anyone ported 1D barcode scanning to iPhone or C++?
See Why don't 1D codes work on iOS devices? in the FAQ (which, FWIW, I wrote).
There are ports of 1D decoders but while there is lots of interest, no one has stepped up to maintain them. They're out of date with respect to the Java decoders which shows in their lower accuracy on the ZXing test set.
