篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了IOS技术分享| ARCallPlus 开源项目相关的知识，希望对你有一定的参考价值。
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）
核心 API 和回调
@interface ARUICalling : NSObject
+ (instancetype)shareInstance;
/// 通话接口
/// @param users 用户信息
/// @param type 呼叫类型：视频/语音
- (void)call:(NSArray<ARCallUser *> *)users type:(ARUICallingType)type;
/// 通话回调
/// @param listener 回调
- (void)setCallingListener:(id<ARUICallingListerner>)listener;
/// 设置铃声，建议在30s以内，只支持本地音频文件
/// @param filePath 音频文件路径

/// 开启静音模式（默认关）
- (void)enableMuteMode:(BOOL)enable;
/// 开启自定义路由（默认关）
/// @param enable 打开后，在onStart回调中，会收到对应的ViewController对象，可以自行决定视图展示方式
- (void)enableCustomViewRoute:(BOOL)enable;
@end

// 收到呼叫时，先通过此方法询问是否可以唤起被叫UI.
// 返回为true，直接唤起UI。返回为false，内部返回忙线
// 不实现默认直接可以唤起UI

/// 呼叫开始回调。主叫、被叫均会触发；
/// 被叫触发时，会将控制器通过监听回调出来，由接入方决定显示方案。
/// @param userIDs 本次通话用户id（自己除外）
/// @param type 通话类型:视频\\音频
/// @param role 通话角色:主叫\\被叫
/// @param viewController 提供Calling功能页面给调用方，可以让用户在此基础上自定义
- (void)callStart:(NSArray<NSString *> *)userIDs type:(ARUICallingType)type role:(ARUICallingRole)role viewController:(UIViewController * _Nullable)viewController NS_SWIFT_NAME(callStart(userIDs:type:role:viewController:));
/// 通话结束回调
/// @param userIDs 本次通话用户id（自己除外）
/// @param type 通话类型:视频\\音频
/// @param role 通话角色:主叫\\被叫
/// @param totalTime 通话时长
- (void)callEnd:(NSArray<NSString *> *)userIDs type:(ARUICallingType)type role:(ARUICallingRole)role totalTime:(float)totalTime NS_SWIFT_NAME(callEnd(userIDs:type:role:totalTime:));
/// 通话事件回调
/// @param event 回调事件类型
/// @param type 通话类型:视频\\音频
/// @param role 通话角色:主叫\\被叫
/// @param message 事件
- (void)onCallEvent:(ARUICallingEvent)event type:(ARUICallingType)type role:(ARUICallingRole)role message:(NSString *)message NS_SWIFT_NAME(onCallEvent(event:type:role:message:));
/// 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
