在iOS自定义键盘中使用时不支持iOS CoreBluetooth状态 [英] iOS CoreBluetooth state unsupported when using in iOS custom keyboard

问题描述

我想在iOS键盘扩展（自定义键盘）中使用 CoreBluetooth API。但是，不支持 CBCentralManager 的状态。我使用的设备是iPhone6。它在容器应用程序内正常运行。这是否意味着 CoreBluetooth API不能在键盘扩展名内使用？

I want to use CoreBluetooth API within iOS keyboard extension (custom keyboard). However, the state for the CBCentralManager is unsupported. The device I use is iPhone 6. It works fine inside the container app. Does this mean that the CoreBluetooth API cannot be used inside the keyboard extension?

推荐答案

您需要在NSExtension> NSExtensionAttributes下的扩展程序的plist中将 RequestOpenAccess 设置为YES。

You will need to set RequestOpenAccess to YES in your extension's plist under NSExtension > NSExtensionAttributes.

设置此项设为是将允许扩展访问网络资源。蓝牙被视为网络资源，因此当 RequestOpenAccess 为否时，您将获得 CBManagerStateUnsupported 。

Setting this to YES allows the extension to access network resources. Bluetooth is considered a network resource so you will get CBManagerStateUnsupported when RequestOpenAccess is NO.
