iPad QR Code Generator Introduction
iPad QR Code is a QR Code barcode generator component developed for iPad apps developers who need add QR Code creation features into their developmental projects for iPad.
- Generate QR Code barcodes on iPad client apps, without communicating with a server
- QR Code barcode generation support on desktops as well as servers
- iPad QR Code Generator Guide provided with iPad QR Code generation sample
A 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.
Valid Data Scope
iPad QRCode 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 on your iPad applications?
- Create a barcode object
- Set barcode properties
- 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];
}
