Hello,
im trying to call from my View Controller a NFC Reader in a different ViewController. The NFC Reader starts but doesn't calls:
func readerSession(_ session: NFCNDEFReaderSession, didDetectNDEFs...)
I can call the NFC Reader in the other ViewController but don't use reader output because i think, that he doesn't calls the didDetectNDEF function.
Thanks for Help
i'm trying to call from my View Controller a NFC Reader in a different ViewController.
What do you do exactly ? Are you sure the second controller is already loaded when you call ?
If both ViewControllers are loaded did you try to push notification or use delegation ?
I´m calling the readNFC function which is in ViewControllerB from MainController. The readNFC function normally calls function didDetectNDEFs or didInvalidateWithError. I have in both functions a print("...") but I don't get it printed into the Terminal/ Console. Because of that, I think that the readNFC function doesn't calls the other.
Show the code of both controllers.
It is important to check how you call.
What is the sequence of events ? Is it this one ?
Please explain more.
