restartPolling()
Restarts the polling sequence so the reader session can discover new tags.
Declaration
func restartPolling()Discussion
After restarting the polling sequence, the reader session sends newly detected tags to the session’s delegate method readerSession(_:didDetect:).
Calling restartPolling() has no effect when:
The session is invalid. If you need to restart the reader session, create a new NFCNDEFReaderSession.
The session’s delegate doesn’t implement the readerSession(_:didDetect:) method. When this method is missing, the session calls readerSession(_:didDetectNDEFs:) to inform the delegate of new NDEF messages, then restarts the polling sequence.
