## AgoraRtcEngineDelegate [#agorartcenginedelegate]

启用应用程序的回调事件通知。

<a id="class_irtcengineeventhandler__detailed_desc"></a>

:::info[自从]
自 v1.1 版本新增。
:::

SDK 通过 [AgoraRtcEngineDelegate](/zh-CN/api-reference/rtc/macos/rtc-interface-class#class_irtcengineeventhandler) 协议中的代理回调向应用报告运行时事件。从 v1.1 版本起，SDK 中部分 block 回调被代理回调替代。旧的 block 回调虽已废弃，但当前版本仍支持使用。声网建议你将 block 回调替换为代理回调。如果同时定义了 block 和代理回调，SDK 将优先调用 block 回调。
