An 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.

 

Valid Data Scope

iPad Barcode EAN-13 supports:

  • 0, 1, 2, 3, 4, 5, 6, 7, 8, 9

 

How to generate barcode in Objective-C on your iPad applications?

  1. Create a barcode object
  2. Set barcode properties
  3. 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];
    
}
