iPhone Data Matrix Barcode Generator Introduction

iPhone Data Matrix Generator SDK is a Data Matrix generator component designed for iOS project developers who need add Data Matrix creation features into their developmental applications for iPhone.

  • Data Matrix generation support on desktops as well as servers
  • Generate Data Matrix on iPhone client apps, without communicating with a server
  • Complete iPhone Data Matrix Generator Guide provided with iPhone Data Matrix generation demo project

Data Matrix code is a two-dimensional matrix barcode consisting of black and white "cells" or modules arranged in either a square or rectangular pattern. The information to be encoded can be text or raw data. Usual data size is from a few bytes up to 2 kilobytes. The length of the encoded data depends on the symbol dimension used. Error correction codes are added to increase symbol strength: even if they are partially damaged, they can still be read. A Data Matrix symbol can store up to 2,335 alphanumeric characters.


Data Matrix Valid Data Scope

iPhone Barcode Data Matrix 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?

  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];

iPhone Data Matrix Generator - Barcode Properties

Category Class Properties Default Comments
Basic pData "" NSString. Data matrix value to encode
Data Matrix
bProcessTilde false BOOL.
Set the bProcessTilde property to true, if you want use the tilde character "~" to specify special characters in the input data. Default is false.
  • ~3: is used only at the very beginning of the symbol for the reader programming purpose.
  • ~5: is used only at the very beginning of the symbol, the header [)> + ASCII 30 + ASCII 05 + ASCII 29 will be transmitted by the barcode reader before the data in the message and the trailer ASCII 30 + ASCII 4 will be transmitted afterwards.
  • ~6: is used only at the very beginning of the symbol, the header [)> + ASCII 30 + ASCII 06 + ASCII 29 will be transmitted by the barcode reader before the data in the message and the trailer ASCII 30 + ASCII 4 will be transmitted afterwards.
  • ~7NNNNNN: is used to specify the Extended Channel Interpretations and NNNNNN is a value between 000000 and 999999.
  • ~NNN: is used to represent the ASCII character with the value of NNN. NNN is from 000 to 255
nDataMode 0 int.
Set the nDataMode property.
Valid values are
OB_DATAMATRIX_Edifact = 5,
OB_DATAMATRIX_Base256 = 6,
OB_DATAMATRIX_Customer = 7
  • Auto (0): Barcode library will decide the best data mode for you.
  • ASCII (1): it is used to encode data that mainly contains ASCII characters (0-127). This is the default encoding format by Barcode Library.
  • C40 (2): it is used to encode data that mainly contains numeric and upper case characters.
  • Text (3): it is used to encode data that mainly contains numeric and lower case characters.
  • X12 (4):it is used to encode the standard ANSI X12 electronic data interchange characters.
  • EDIFACT (5): it is used to encode 63 ASCII values (values from 32 to 94) plus an Unlatch character (binary 011111).
  • Base256 (6): it is used to encode 8 bit values.
