我在 Xamarin IOS 上设置 NFC 读取器时遇到问题。配置示例如下： https: //learn.microsoft.com/en-us/xamarin/ios/platform/introduction-to-ios11/corenfc
启动应用程序后，NFCNdefReaderSession.ReadingAvailable 始终为 false，并且在设备日志中：
[NFCNDEFReaderSession beginSession]:255 error:Error Domain=NSCocoaErrorDomain Code=4099 "The connection to service named com.apple.nfcd.service.corenfc was invalidated from this process." UserInfo={NSDebugDescription=The connection to service named com.apple.nfcd.service.corenfc was invalidated from this process.}
