问题
I want to present a DataMatrix from a given String in an iOS App (NOT a barcode), but can not found any working SDK, guide or even hint to a solution. The only thing I found was a way to READ it, but it looks like the AVFoundation can't be used to SHOW it.
Would be very thankful for every hint to this topic.
