CoreNFC调试无法正常工作

如何在xcode-9上以编程方式工作CoreNFC

func readerSession(_ session: NFCNDEFReaderSession, didInvalidateWithError error: Error) {
    //What I need to do here
}

func readerSession(_ session: NFCNDEFReaderSession, didDetectNDEFs messages: [NFCNDEFMessage]) {
    //What I need to do here
}

override func viewDidLoad() {
    super.viewDidLoad()

    let sessiOnReader= NFCNDEFReaderSession.init(delegate: self, queue: nil, invalidateAfterFirstRead: true)
    let nfcSession = NFCReaderSession.self

    let nfcTag = NFCTagCommandConfiguration.init()
    let tagType = NFCTagType(rawValue: 0)

    sessionReader.begin()

}

我想知道读取一些NFC标签需要做些什么.

它有四个步骤可以使它工作:

将NFC标签权限添加到Apple开发人员门户中的应用标识符

将Code Signing Entitlement文件添加到项目并构建设置,并添加以下原始键和值:

将使用说明添加到Info.plist:

实现委托并将其传递给NFCNDEFReaderSessioninit,如下所示:

import UIKit
import CoreNFC

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate, NFCNDEFReaderSessionDelegate {

    var window: UIWindow?
    var session: NFCNDEFReaderSession?

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
        session = NFCNDEFReaderSession(delegate: self, queue: nil, invalidateAfterFirstRead: false)
        self.session?.begin()
        return true
    }

    func readerSession(_ session: NFCNDEFReaderSession, didInvalidateWithError error: Error) {
        print(error)
    }

    func readerSession(_ session: NFCNDEFReaderSession, didDetectNDEFs messages: [NFCNDEFMessage]) {
        print(messages)
    }

}

}
