restartPolling(with:)

Declaration

func restartPolling(with configuration: NFCTagReaderSessionConfiguration)

Parameters

  • configuration:

    Reader configuration used for the polling restart. The configuration does not persist in the current active session, i.e. [NFCTagReaderSession restartPolling] would use the original configuration from session instance initialization.

Discussion

Restart the polling sequence in this session to discover new tags using the provided configuration. New tags discovered from polling will return in the subsequent [NFCTagReaderSessionDelegate tagReaderSession:didDetectTags:] call. Tags that are returned previously by [NFCTagReaderSessionDelegate tagReaderSession:didDetectTags:] will become invalid, and all references to these tags shall be removed to properly release the resources. Calling this method on an invalidated session will have no effect; a new reader session is required to restart the reader.
