CoreNFC调试无法正常工作

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()

}

我想知道读取一些NFC标签需要做些什么。

Answer 1

有四个步骤可以让它发挥作用：

1. 将NFC标签权限添加到Apple开发人员门户网站中的应用标识符



1. 将代码签名授权文件添加到项目并构建设置，并添加以下原始密钥和值：



1. 将使用说明添加到Info.plist：



1. 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)
   }
   

   }
