ARCallPlus 简介
ARCallPlus 是开源的音视频通话项目，同时支持iOS、Android、Web等平台。本文主要介绍音视频通话 ARUICalling 模块 iOS 本地库的封装。
源码下载
三行代码、二十分钟应用内构建，实现音视频通话。本项目已上架App Store，欢迎下载体验。
开发环境
-
开发工具：Xcode13 真机运行
-
开发语言：Objective-C、Swift
项目结构
核心 API:
- ARUILogin（登录 API）
- ARUICalling（通话 API）
- ARUICallingListerner（通话回调）
内部核心 API:
- ARTCCalling（音视频）
- ARTCCallingDelegate（音视频回调）
- ARTCCalling+Signal（实时消息）
