  1. 创建引擎并初始化。

    域名保持默认值即可，appId请提交工单申请。

    _rtcEngine = [HWRtcEngine sharedEngine];
[_rtcEngine init:domain appId:appId];

  2. 设置本地窗口。

    _localVideoSession = [[HWVideoSession alloc] initWithUserID:self.userName];
HwRtcVideoView *videoView = [[HwRtcVideoView alloc] initWithFrame:self.view.bounds];
_localVideoSession.videoView = videoView;
_localVideoSession.userName= self.userName;
_localVideoSession.isPlaying = YES;
[_rtcEngine setupLocalVideo:_localVideoSession.canvas viewMode:self.displayMode];

  3. 加入房间。

    HWRtcUserInfo *userInfo = [[HWRtcUserInfo alloc]init];
userInfo.role = cameraVC.roleType;
userInfo.userId = cameraVC.userName;
userInfo.userName = cameraVC.userName;
BOOL result = [self.rtcEngine joinRoom:userInfo roomId:cameraVC.roomId mediaType:HWRtcMediaTypeVideo];

  4. 监听远端用户加入房间，并设置远端窗口。

    -(void)onUserJoined:(NSString*)roomId userId:(NSString*)userId userName:(NSString*)userName{
    if([userId isEqualToString:localUid] || self.roleType ==HWRtcRolePublisher){
        return;
    }
    @synchronized (self) {
         dispatch_async(dispatch_get_main_queue(),
                          ^{         
             HWVideoSession *videoSession = [[HWVideoSession alloc] initWithUserID:userId];
             videoSession.userName = userId;
             HwRtcVideoView *videoView = [[HwRtcVideoView alloc] initWithFrame:CGRectMake(0, 0, 90, 160)];
             videoSession.videoView = videoView;
             videoSession.isPlaying = YES;
             [self.cameraView addSubview:videoView];
             int result = [self.rtcEngine startRemoteStreamView:videoSession.canvas treamType:self.streamType];
            if (result == 0) {
                 [self.rtcEngine setRemoteViewDisplayMode:self.displayMode userid:userId];
             }
             [self.viewsArray addObject:videoSession];

        });
     }
}

  5. 监听远端用户离开房间，并删除远端窗口。

{
    if(self.roleType == HWRtcRolePublisher){
        return;
    }
    dispatch_async(dispatch_get_main_queue(),
    ^{
        for (HWVideoSession* offlineVideoSession in self.viewsArray) {
            if ([userId isEqualToString:videoSession.canvas.uid]) {
             [self.viewsArray removeObject:offlineVideoSession];
            }
        }
    });
}

  6. 离开房间。

    [_rtcEngine leaveRoom];
