ios - IOS 使用的 ExternalAccessory 协议是什么

Question

请问，如何在我的代码中指定外部附件使用的协议？在我的 info.plist 文件中，我输入了密钥，但我不知道我必须在项目中输入什么。谢谢

Answer 1

Examine the protocolStrings property of the EAAccessory object when you receive a EAAccessoryDidConnect notification. Those are the protocols you should put in your info.plist file, under the key UISupportedExternalAccessoryProtocols

For example,

<key>UISupportedExternalAccessoryProtocols</key>
<array>
    <string>PROTOCOL_NAME_HERE</string>
    <string>PROTOCOL_NAME_HERE</string>
</array>

If you're unsure about how to implement the EAAccessoryDelegate protocol to obtain what I describe above, have a look at EADemo sample from Apple

Answer 2

大多数时候，您从硬件制造商处获得协议名称。

例如，如果您使用 Pebble watch 开发 iOS 应用程序，则该值将为“com.getpebble.public”
