Bluetooth iOS 10.0和x2B上的蓝牙授权（外部附件）问题；

每次我试图通过iOS 10.0+（本机或Xamarin）上的ExternalAccessment SDK列出已连接的蓝牙附件时，我都会收到以下日志消息：

Couldn't find the "com.apple.private.externalaccessory.showallaccessories" entitlement

（Swift）

（Xamarin.iOS）

我的Info.plist看起来像：

ui背景模式
这也使用了ExternalAccessSDK，我也遇到了
com.apple.private.ExternalAccessory.showallaccessories
问题

我错过什么了吗？有人知道解决办法吗？谢谢

let devices = EAAccessoryManager.shared().connectedAccessories

var devices = EAAccessoryManager.SharedAccessoryManager.ConnectedAccessories;
