QR generation for iOS

[lostintheplanet]

Hi there,

I would like to generate QRcode for merchant app.

I see iOS mVisa SDK can ganarate QRCode, however, it is a GUI built-in, I would like to ganarate QRCode image only and use it for our app.

I also see "QR Utility SDK", but it is for Android.

Currently, I can genarete the QRCode, but it seems that the CRC is not correct. I am using this: 

https://stackoverflow.com/questions/15140699/nsdata-to-crc-16

 My QRString: 00020101021202164311190000119821520415205303356540515.815802IN5903KFC6006MUMBAI6304e378

Could you please help provide a method to calculate CRC for iOS.

Thank you,

Hiep Nguyen

Hi,

I would like to ask if how did you get the string of the generated QR code? I'm also implementing that feature on our app, and my problem is, i can't get that string, it only display on logs. Thank you.
