Multiple scanning on IOS - code sample request

[chrisfinch]

Firstly, thankyou for your open source software and contribution to the community, I appreciate you do this in your free time and am thankful for the software you have provided through your hard work. Making the below issue as clear as possible;

Request

A working code sample showing how to implement multiple scanning using react-native-nfc-manager

Scenario

React-Native app where the user can toggle on bulk scanning mode and scan multiple tags without any user interaction between scans.

"react-native-nfc-manager": "^3.17.1"
"react-native": "0.76.3",
"react": "18.3.1",

Requirements

• NFC tag ID tag.id must be received (use as identifier in API requests)
• Working on both IOS and Android platforms
• No user interaction between tag scans
  • No limit to number of tags scanned
  • User can 'cancel' the scanning to exit the bulk scanning flow and view their results
• NDEF + MiFare

Methods tried before

I have spend considerable time trying to resolve before asking here.

• How to continuously read tags? #269 I have tried to use this method and cannot get it to work
• Reading multiple non-NDEF tags in a single session - iOS #774, Can iOS read multiple tags without dismissing its UI? #720 I have tried using NfcManager.restartTechnologyRequestIOS() as mentioned but cannot get it to work
• Youtube - Build an NFC Phone Tag Game for iOS and Android with Richie Hsieh, ex-software lead at MediaTek I have got this method working for multiple scans however no tag.id is present on received tag.

If anyone can help me with a complete, working code sample I would be very grateful. Thankyou.

I've investigated further. It seems that the promise based version (eg: await NfCManaged.getTag()of the tag scanning flow cannot work for multiple tag scanning. The issue is using a while loop without getting an infinite loop resolving with the previously scanned tag.

When using the events based flow (eg: NfcManager.setEventListener(NfcEvents.DiscoverTag, tag => {) the scanning works correctly, but I do not have access to the NDEF tag ID on IOS.

Can anyone advise how to retrieve the tag id using NDFE on IOS with NfcEvents.DiscoverTag?

@whitedogg13 apologies for tagging you, I know you must be busy - do you know how to get tag.id from a NfcEvents.DiscoverTag on IOS?
