未检测到 iOS 13、Swift 5、Core NFC MiFare Classic 1K

Question

我在使用 ios 13+ 和 swift 5 从 rfid 芯片读取数据时遇到一个非常基本的问题，我有两个设置（NFCNDEFReaderSession 和 NFCTagReaderSession），

\n\n

NFCNDEF阅读器会话：

\n\n

import UIKit\nimport CoreNFC\n\nclass ViewController: UIViewController {\n\n    var session: NFCNDEFReaderSession?\n\n    override func viewDidLoad() {\n        super.viewDidLoad()\n\n        session = NFCNDEFReaderSession(delegate: self, queue: DispatchQueue.main, invalidateAfterFirstRead: false)\n        session?.begin()\n    }\n\n}\n\nextension ViewController: NFCNDEFReaderSessionDelegate {\n\n    func readerSessionDidBecomeActive(_ session: NFCNDEFReaderSession) {\n        print("active") // called once\n    }\n\n    func readerSession(_ session: NFCNDEFReaderSession, didDetectNDEFs messages: [NFCNDEFMessage]) {\n        print("didDetectNDEFs") // never called\n    }\n\n    func readerSession(_ session: NFCNDEFReaderSession, didInvalidateWithError error: Error) {\n        print(error.localizedDescription) // only called on timeout\n    }\n\n}\n

\n\n

NFCTagReader会话：

\n\n

import UIKit\nimport CoreNFC\n\nclass ViewController: UIViewController {\n\n    var session: NFCTagReaderSession?\n\n    override func viewDidLoad() {\n        super.viewDidLoad()\n\n        session = NFCTagReaderSession(pollingOption: NFCTagReaderSession.PollingOption.iso14443, delegate: self, queue: DispatchQueue.main)\n        session?.begin()\n    }\n\n}\n\nextension ViewController: NFCTagReaderSessionDelegate {\n\n    public func tagReaderSessionDidBecomeActive(_ session: NFCTagReaderSession) {\n        print("active") // called once\n    }\n\n    public func tagReaderSession(_ session: NFCTagReaderSession, didDetect tags: [NFCTag]) {\n        print("didDetect") // never called\n    }\n\n    public func tagReaderSession(_ session: NFCTagReaderSession, didInvalidateWithError error: Error) {\n        print(error.localizedDescription) // only called on timeout\n    }\n\n}\n

在这两种情况下，“didDetectNDEFs”和“didDetect”方法都不会被调用。

我浏览了苹果文档：\n https://developer.apple.com/documentation/corenfc \n他们实际上声称这是可能的（用于检测 ISO7816、ISO15693、FeliCa 和 MIFARE 标签的读者会话。），但是如何呢？ ..

\n\n

此人还声称他可以从这些 rfid 芯片中读取数据：\n使用 CoreNFC 检测 ISO/IEC 14443（Mifare Ultralight 或 Classic）NFC 卡
