Class NFCTagReaderSession

  • All Implemented Interfaces:
    NFCReaderSession, NSObject
    public class NFCTagReaderSession
extends NFCReaderSession
    NFCTagReaderSession Reader session for processing NFC tags supporting one of the @link NFCTagType @link/ types. @link [NFCTagReaderSessionDelegate readerSession:didDetectTags:] @link/ will return tag objects matching the requested type for the session. This session requires the "com.apple.developer.nfc.readersession.formats" entitlement in your process. In addition your application's Info.plist must contain a non-empty usage description string. @link NFCReaderErrorSecurityViolation @link/ will be returned from @link [NFCTagReaderSessionDelegate tagReaderSession:didInvalidateWithError:] @link/ if the required entitlement is missing when session is started. NOTE: - Only one NFCReaderSession can be active at any time in the system. Subsequent opened sessions will get queued up and processed by the system in FIFO order. - If the session is configured with @link NFCPollingISO14443 @link/ and an ISO7816 compliant MiFare tag that contains one of the applications listed in the "com.apple.developer.nfc.readersession.iso7816.select-identifiers" array in Info.plist is found, then @link [NFCTagReaderSessionDelegate readerSession:didDetectTags:] @link/ will return a tag instance conform to the @link NFCISO7816Tag @link/ protocol.

      • connectToTagCompletionHandler

        public void connectToTagCompletionHandler​(NFCTag tag,
                                          NFCTagReaderSession.Block_connectToTagCompletionHandler completionHandler)
        connectToTag:completionHandler: This method establishes a tag connection and activates the tag. Connecting to the same tag that is currently opened has no effect. Connecting to a different tag will automatically terminate the previous tag connection and put it into the halt state. Tag stays in the connected state until another tag is connected or the polling is restarted.
        Parameters:
        tag - A NFCTag protocol compliant tag object that will be connected to.
        completionHandler - Completion handler called when the operation is completed. error is nil if operation succeeds. A @link NFCErrorDomain @link/ error is returned when there is a communication issue with the tag.

      • connectedTag

        public NFCTag connectedTag()
        [@property] connectedTag Current connected tag object; nil if no tag is connected in the session.

        initWithPollingOption:delegate:queue:
        Parameters:
        pollingOption - Configures the RF polling of the reader session; multiple options can be OR'ed together. This option affects the possible NFC tag type discover.
        delegate - The session will hold a weak ARC reference to this @link NFCTagReaderSessionDelegate @link/ object.
        queue - A dispatch queue where NFCTagReaderSessionDelegate delegate callbacks will be dispatched to. A nil value will cause the creation of a serial dispatch queue internally for the session. The session object will retain the provided dispatch queue.
        Returns:
        A new NFCTagReaderSession instance.
