ARCallPlus 简介
ARCallPlus 是 anyRTC 开源的音视频通话项目，同时支持ios、android、Web等平台。上一篇我们介绍了ARUICalling 开源组件的封装，本篇主要介绍如何通过 ARUICalling 组件来实现音视频通话效果。
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
示例 demo 目录:
- LoginViewController （登录）
- RegisterViewController （注册）
- MainViewController （首页）
- CallingViewController（发起音视频通话）
- MineViewController （我的）
ARUICalling组件核心 API:
- ARUILogin（登录 API）
- ARUICalling（通话 API）
- ARUICallingListerner（通话回调）
组件集成
步骤一：导入 ARUICalling 组件
通过 cocoapods 导入组件，具体步骤如下：
- 在您的工程 Podfile 文件同一级目录下创建 ARUICalling 文件夹。
- 从 Github 下载代码，然后将 ARUICalling/iOS/ 目录下的 Source、Resources 文件夹 和 ARUICalling.podspec 文件拷贝到您在 步骤1 创建的 ARUICalling 文件夹下。
- 在您的 Podfile 文件中添加以下依赖，之后执行 pod install 命令，完成导入。
# :path => "指向ARUICalling.podspec的相对路径" pod ARUICalling, :path => "ARUICalling/ARUICalling.podspec", :subspecs => ["RTC"]
步骤二：配置权限
-
使用音视频功能，需要授权麦克风和摄像头的使用权限。
<key>NSCameraUsageDescription</key> <string>ARCallPlus请求访问麦克风用于视频通话？</string> <key>NSMicrophoneUsageDescription</key> <string>ARCallPlus请求访问麦克风用于语音交流？</string>
- 推送权限（可选）
步骤三：初始化组件
anyRTC 为 App 开发者签发的 App ID。每个项目都应该有一个独一无二的 App ID。如果你的开发包里没有 App ID，请从anyRTC官网(https://www.anyrtc.io)申请一个新的 App ID
/// 初始化
ARUILogin.initWithSdkAppID(AppID)
/// 登录
ARUILogin.login(localUserModel!)
success()
print("Calling - login sucess")
fail: code in
failed(code.rawValue)
print("Calling - login fail")
步骤四：实现音视频通话
/// 发起通话
ARUICalling.shareInstance().call(users: ["123"], type: .video)
/// 通话回调
ARUICalling.shareInstance().setCallingListener(listener: self)步骤五：离线推送（可选）
如果您的业务场景需要在 App 的进程被杀死后或者 App 退到后台后，还可以正常接收到音视频通话请求，就需要为 ARUICalling 组件增加推送功能，可参考demo中推送逻辑（极光推送为例）。
// MARK: - ARUICallingListerner
/// 推送事件回调
/// @param userIDs 不在线的用户id
/// @param type 通话类型:视频\\音频
- (void)onPushToOfflineUser:(NSArray<NSString *> *)userIDs type:(ARUICallingType)type;示例代码
