iPhone EAN-13 Barcode Generator Introduction
iPhone EAN-13 Generator SDK is a EAN-13 generator component designed for iOS project developers who need add EAN-13 creation features into their developmental applications for iPhone.
- EAN-13 generation support on desktops as well as servers
- Generate EAN-13 on iPhone client apps, without communicating with a server
- Complete iPhone EAN-13 Generator Guide provided with iPhone EAN 13 generation demo project
EAN-13 barcode (originally European Article Number) is a barcoding standard which is a superset of the original 12-digit Universal Product Code (UPC) system developed in the United States.

The EAN-13 barcode is defined by the standards organisation GS1. The numbers encoded in EAN-13 bar codes are product identification numbers which are called Japanese Article Number (JAN) in Japan. All the numbers encoded in UPC and EAN barcodes are known as Global Trade Item Numbers (GTIN), and they can be encoded in other GS1 barcodes.
EAN-13 Valid Data Scope
iPhone Barcode EAN13 supports:
- 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
How to generate barcode in Objective-C?
- Create a barcode object
- Set barcode properties
- call drawWithView() method, to paint barcode on the canvas.
Sample Code:
- (void)drawRect:(CGRect)rect {
// Drawing code
OBLinear *pLinear = [OBLinear new];
[pLinear setNBarcodeType: OB_CODE128A];
[pLinear setPDataMsg: [[NSString alloc] initWithString: (@"AB")]];
//[pLinear setPSupData: [[NSString alloc] initWithString: (@"14562")]];
[pLinear setFX: USER_DEF_BAR_WIDTH];
[pLinear setFY: USER_DEF_BAR_HEIGHT];
[pLinear setFLeftMargin: (USER_DEF_LEFT_MARGIN)];
[pLinear setFRightMargin: (USER_DEF_RIGHT_MARGIN)];
[pLinear setFTopMargin: (USER_DEF_TOP_MARGIN)];
[pLinear setFBottomMargin: (USER_DEF_BOTTOM_MARGIN)];
[pLinear setNRotate: (OB_Rotate0)];
UIFont *pTextFont = [UIFont fontWithName: @"Arial" size: 8.0f];
[pLinear setPTextFont: pTextFont];
[pLinear drawWithView: (self)];
[pLinear release];
}
