Question

I am looking for a free API for generating linear barcodes in iPhone. I had found one zxing library for generating barcodes but it generates only QR code.
Please suggest me a library for generating linear bar codes.
Thanks.

Answer 1

I found this project easy to learn.

https://github.com/netshade/Cocoa-Touch-Barcodes

For a quick demonstration
There are several other barcode types this project renders, just make sure to import the header for your specific need.

Add the files from the Cocoa-Touch-Barcodes project into your Xcode project.

In the class you will use to help display the barcode

#import "UIImage-NKDBarcode.h"
#import "NKDEAN13Barcode.h"

-(void)showBarcode {
     NKDBarcode * nkdbarcode = [[NKDEAN13Barcode alloc] initWithContent:@"1234567890123"];
     UIImage * image = [UIImage imageFromBarcode:nkdbarcode];
     // assume barcodeIV is an outlet to an imageview
     [barcodeIV setImage:image];
}
