Xamarin IOS NFCNdefReaderSession.ReadingAvailable 为 false

Question

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.}

Answer 1

在 IOS 项目设置 -> IOS Bundle Singing -> Custom Entitlements 中 - 在我的项目中它是空白的。只需将其设置为您的 Entitlements.plist
