CoreNFC 调试不工作

Question

如何以编程方式在 xcode-9

上运行 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()

}

我想知道我需要做什么才能读取一些 NFC 标签。

需要四个步骤才能使其正常工作：

在 Apple 开发者门户中将 NFC 标签权限添加到您的 App Identifier

将代码签名授权文件添加到您的项目和构建设置，并添加以下原始键和值：

将使用说明添加到您的 Info.plist:

实现委托并将其传递给 NFCNDEFReaderSession init，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)
    }

}
