iPhone Code 39 Barcode Generator Introduction

iPhone Code 39 Generator SDK is a Code 39 generator component designed for iOS project developers who need add Code 39 creation features into their developmental applications for iPhone.

  • Code 39 generation support on desktops as well as servers
  • Generate Code 39 on iPhone client apps, without communicating with a server
  • Complete iPhone Code 39 Generator Guide provided with iPhone Code 39 generation demo project

Code 39 (also known as "USS Code 39", "Code 3/9", "Code 3 of 9", "USD-3", "Alpha39", "Type 39") is a barcode symbology that can encode uppercase letters (A through Z), digits (0 through 9) and a handful of special characters like the $ sign.

Code 39 is restricted to 44 characters. In Full ASCII Code 39 Symbols 0-9, A-Z, "." ,and "-" are the same as their representations in Code 39. Lower case letters, additional punctuation characters and control characters are represented by sequences of two characters of Code 39.

 

Code-39 Valid Data Scope

iPhone Barcode Code 39 supports:

  • 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
  • Uppercase letters (A - Z)
  • - (Dash), $ (Dollar), % (Percentage), (Space), . (Point), / (Slash), + (Plus)

iPhone Barcode Code 39 Extension supports:

  • all 128 ASCII characters

 

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];
    
}
