iPhone QR Code Barcode Generator Introduction

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

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

QR Code is a matrix code (or two-dimensional bar code) created by Japanese corporation Denso-Wave in 1994. The "QR" is derived from "Quick Response", as the creator intended the code to allow its contents to be decoded at high speed.

 

QR Code Valid Data Scope

iPhone QR Code supports:

  • numeric data (digits 0 - 9);
  • alphanumeric data (digits 0 - 9; upper case letters A -Z; nine other characters: space, $ % * + - . / : );
  • byte data (default: ISO/IEC 8859-1);
  • Kanji 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];
    
}
