Provided Methods

unsafe fn readerSessionDidBecomeActive(&self, session: &NFCReaderSession)

where Self: Sized + Message,

Parameter session: The session object in the active state.

Gets called when the NFC reader session has become active. RF is enabled and reader is scanning for tags. The

 readerSession:didDetectTags: @link/ will be called when a tag is detected.
  

unsafe fn readerSession_didInvalidateWithError( &self, session: &NFCReaderSession, error: &NSError, )

where Self: Sized + Message,

Parameter session: The session object that is invalidated.

Parameter error: The error indicates the invalidation reason.

Gets called when a session becomes invalid. At this point the client is expected to discard the returned session object.

unsafe fn readerSession_didDetectTags( &self, session: &NFCReaderSession, tags: &NSArray<ProtocolObject<dyn NFCTag>>, )

where Self: Sized + Message,

Parameter session: The session object used for tag detection.

Parameter tags: Array of

 NFCTag @link/ objects.

 @discussion      Gets called when the reader detects NFC tag(s) in the polling sequence.
