iPad Code 128 Generator Introduction

iPad Code 128 is a Code 128 barcode generator component developed for iPad apps developers who need add Code 128 creation features into their developmental projects for iPad.

  • Generate Code 128 barcodes on iPad client apps, without communicating with a server
  • Code 128 barcode generation support on desktops as well as servers
  • iPad Code 128 Generator Guide provided with iPad Code 128 generation sample

Code 128 is a very high-density barcode symbology. (A special version of it called GS1-128 is used extensively world wide in shipping and packaging industries.) It is used for alphanumeric or numeric-only barcodes.

Valid Data Scope

iPad Barcode Code 128 supports:

  • all 128 characters of ASCII
  • values 128-255 in accordance with ISO 8859-1. There are referred to as extended ASCII.

 

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];
    
}
