Does anyone have an example application or idea about generating QR CODE generation using some user input like ID, Name, Address, etc.
thanks.
You can choose here to generate a QR code.
this is a third-party library 1) https://github.com/myang-git/QR-Code-Encoder-for-Objective-C 2) https://github.com/kuapay/iOS-QR-Code-Generator
but if you really want to know the concept, this is a good start http://www.onbarcode.com/products/iphone_barcode/barcodes/qrcode.html
