iPhone Barcode Generator Tutorial

How to generate linear and 2d barcodes in your iPhone (iOS) applications using iPhone Barcode Generator?



iPhone Barcode is a iPhone Barcode Generator SDK component which generates and draws multiple 1D (linear) and 2D (matrix) barcodes in your iPhone and iPad applications.

Since iOS SDK version is updating on frequent basis, we deliver the IPhone barcode generator SDK as source code. You can build the source code into library using the proper development environment, i.e. iOS7, iOS8.

    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];
