Index
This Symbology is also known as Universal Product Code version A, UPC-A Supplement 5/Five-digit Add-On, UPC-A Supplement 2/Two-digit Add-On, UPC-A+5, UPC-A+2, UPC Code, UPC Symbol, GTIN-12, GS1-12, UCC-12
Mac UPC-A supports:
  • 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
  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];
    
}

Basic nBarcodeType OB_UPCA (36) OBBarcodeType. Barcode type.
OB_UPCA = 36,
OB_UPCA_2 = 37,
OB_UPCA_5 = 38.
