iOS - idoubs 通话判断对方状态（在线、拒接、无人接听、挂断）

来源：互联网发布：阿里云服务器部署方案编辑：程序博客网时间：2024/05/15 23:49

打开NgnSipService.mm文件中有_mSipCallback变量，用来回调事件状态传值。
我们知道idoubs中原来并没有类似于“对方是否在线” “对方是否挂断电话” 但是实际项目中是有这些需求的。
所以，我们自行加入一些变量，用来判断对方的状态！

1.首先我们在定义_NgnSipCallback中来定义几个私有变量：
这里写图片描述

private:    NgnSipService* mSipService;    NgnBaseService<INgnConfigurationService>* mConfigurationService;    //以下为自己加上的变量    long timeStart;  //记录整个开始拨打的时间    long timeEnd;    //记录整个结束时间    bool isInComing = false;  //判断是否是来电    long inCallTimeStart = 0; //记录接听通话开始的时间    long inCallTimeEnd = 0;   //记录接听结束通话的时间

还要给事件添加几个状态：
这里写图片描述

//枚举typedef enum NgnInviteEventTypes_othere {    OTHER_DEFAULT,  // 对方默认状态    OTHER_ANSWER_NOT, //对方未接听状态    OTHER_ANSWER_OR_REJECT,//对方接听或拒绝状态    OTHER_REJECT //对方拒绝状态}NgnInviteEventTypes_other;//增加属性@property (nonatomic,assign) NgnInviteEventTypes_other otherInCallstate;@property (nonatomic,assign) bool otherNotAnswer;@property (nonatomic,assign) bool otherIsOnLine;

2.找到事件连接状态： tsip_event_code_dialog_connected
再找到 Audio/Video/MSRP(Chat, FileTransfer) 表明是通话的事件
接下来加上代码：

else if (((ngnSipSession = [NgnAVSession getSessionWithId: _sessionId]) != nil) || ((ngnSipSession = [NgnMsrpSession getSessionWithId: _sessionId]) != nil)){                    eargs = [[NgnInviteEventArgs alloc]                             initWithSessionId: _sessionId                             andEvenType:INVITE_EVENT_CONNECTED                             andMediaType:((NgnInviteSession*)ngnSipSession).mediaType                             andSipPhrase:phrase];                    [ngnSipSession setConnectionState:CONN_STATE_CONNECTED];                    [((NgnInviteSession*)ngnSipSession) setState:INVITE_STATE_INCALL];                    //  ---------  拨打电话给对方做判断                    if (!isInComing) {                        NSLog(@"拨出");                        bool otherIsOnLine = true;                        bool otherNotAnswer = false;                        NgnInviteEventTypes_other otherInCallstate = OTHER_DEFAULT;                        timeEnd = [[NSDate date] timeIntervalSince1970];                        if (timeStart == 0) {                            NSLog(@"对方不在线");                            otherIsOnLine = false;                        }                        else{                            otherIsOnLine = true;                            NSLog(@"对方在线");                            NSLog(@"timeEnd - timeStart === %d",timeEnd - timeStart);                            if (timeEnd - timeStart > 28) {                                 NSLog(@"对方没有接听");                                otherNotAnswer = true;                                otherInCallstate = OTHER_ANSWER_NOT;                            }                            else{                                NSLog(@"对方接听或拒绝");                                otherInCallstate = OTHER_ANSWER_OR_REJECT;                                //记录通话开始的时间                                inCallTimeStart = [[NSDate date] timeIntervalSince1970];                            }                            timeStart = 0;                            timeEnd = 0;                        }                        eargs.otherInCallstate = otherInCallstate;                        eargs.otherNotAnswer = otherNotAnswer;                        eargs.otherIsOnLine = otherIsOnLine;                    }                    else{                        NSLog(@"拨入");                    }                    [NgnNotificationCenter postNotificationOnMainThreadWithName:kNgnInviteEventArgs_Name object:eargs];                }

3.找到事件状态： tsip_event_code_dialog_terminated 表明结束
同样在Audio/Video/MSRP(Chat, FileTransfer) 下面做处理：

else if (((ngnSipSession = [NgnAVSession getSessionWithId:_sessionId]) != nil) || ((ngnSipSession = [NgnMsrpSession getSessionWithId: _sessionId]) != nil)){                    eargs = [[NgnInviteEventArgs alloc]                             initWithSessionId:_sessionId                             andEvenType:INVITE_EVENT_TERMINATED                             andMediaType:((NgnInviteSession*)ngnSipSession).mediaType                             andSipPhrase:phrase                             andSipCode:_sipCode];                    [ngnSipSession setConnectionState:CONN_STATE_TERMINATED];                    [((NgnInviteSession*)ngnSipSession) setState:INVITE_STATE_TERMINATED];                    NSLog(@"挂断");                    isInComing = false;                    if (inCallTimeStart!=0) {                        inCallTimeEnd = [[NSDate date] timeIntervalSince1970];                        NSLog(@"结束时间 %ld",inCallTimeEnd);                        NSLog(@"inCallTimeEnd - inCallTimeStart === %ld",inCallTimeEnd - inCallTimeStart);                        if (inCallTimeEnd - inCallTimeStart < 2.8) {                            NSLog(@"对方拒绝");                             eargs.otherInCallstate = OTHER_REJECT;                            inCallTimeEnd = 0;                            inCallTimeStart = 0;                        }                        else{                            NSLog(@"挂断");                        }                    }                    [NgnNotificationCenter postNotificationOnMainThreadWithName:kNgnInviteEventArgs_Name object:eargs];                    if([ngnSipSession isKindOfClass:[NgnAVSession class]]){                        [NgnAVSession releaseSession:(NgnAVSession**)&ngnSipSession];                    }                    else if([ngnSipSession isKindOfClass:[NgnMsrpSession class]]){                        [NgnMsrpSession releaseSession:(NgnMsrpSession**)&ngnSipSession];                    }                }

4.在tsip_m_early_media下记录开始时间：

case tsip_m_early_media:            {                if (((ngnSipSession = [NgnAVSession getSessionWithId:_sessionId]) != nil) || ((ngnSipSession = [NgnMsrpSession getSessionWithId: _sessionId]) != nil)){                    eargs = [[NgnInviteEventArgs alloc] initWithSessionId:ngnSipSession.id                                                              andEvenType:INVITE_EVENT_EARLY_MEDIA                                                             andMediaType:((NgnInviteSession*)ngnSipSession).mediaType                                                             andSipPhrase:phrase];                    timeStart = [[NSDate date] timeIntervalSince1970];                     NSLog(@"开始时间记录 ===== ");                    [NgnNotificationCenter postNotificationOnMainThreadWithName:kNgnInviteEventArgs_Name object:eargs];                }                break;            }

5.最后使用阶段
在通话或者视频界面，通过注册通知中心事件改变状态：

-(void) onInviteEvent:(NSNotification*)notification {    NgnInviteEventArgs* eargs = [notification object];    if(!audioSession || audioSession.id != eargs.sessionId){        return;    }    if (!eargs.otherIsOnLine) {        self.labelStatus.text = @"对方不在线...";//         releases session        [NgnAVSession releaseSession: &audioSession];//         starts timer suicide        [NSTimer scheduledTimerWithTimeInterval: kCallTimerSuicide                                         target: self                                       selector: @selector(timerSuicideTick:)                                       userInfo: nil                                        repeats: NO];        return;    }    if (eargs.otherNotAnswer) {         self.labelStatus.text = @"无人接听...";        NSLog(@"!!!!对方没有接听");        [NgnAVSession releaseSession: &audioSession];        //         starts timer suicide        [NSTimer scheduledTimerWithTimeInterval: kCallTimerSuicide                                         target: self                                       selector: @selector(timerSuicideTick:)                                       userInfo: nil                                        repeats: NO];        return;    }    switch (eargs.otherInCallstate) {        case OTHER_DEFAULT:{            break;        }        case OTHER_ANSWER_NOT:{            self.labelStatus.text = @"无人接听...";            NSLog(@"~~~~~对方没有接听");            break;        }        case OTHER_ANSWER_OR_REJECT:{            self.labelStatus.text = @"对方接听或拒绝...";            NSLog(@"~~~~~对方接听或拒绝");            break;        }        case OTHER_REJECT:{            self.labelStatus.text = @"对方已挂断...";            NSLog(@"~~~~~对方拒接");            // releases session            [NgnAVSession releaseSession: &audioSession];            // starts timer suicide            [NSTimer scheduledTimerWithTimeInterval: kCallTimerSuicide                                             target: self                                           selector: @selector(timerSuicideTick:)                                           userInfo: nil                                            repeats: NO];            return;        }    }    switch (eargs.eventType) {        case INVITE_EVENT_INPROGRESS:        case INVITE_EVENT_INCOMING:        case INVITE_EVENT_RINGING:        case INVITE_EVENT_LOCAL_HOLD_OK:        case INVITE_EVENT_REMOTE_HOLD:        default:        {            // updates view and state            [self updateViewAndState];            break;        }            // transilient events        case INVITE_EVENT_MEDIA_UPDATING:        {            self.labelStatus.text = @"语音来电..";            break;        }        case INVITE_EVENT_MEDIA_UPDATED:        {            self.labelStatus.text = @"语音结束中..";            break;        }        case INVITE_EVENT_TERMINATED:        case INVITE_EVENT_TERMWAIT:        {            // updates view and state            [self updateViewAndState];            // releases session            [NgnAVSession releaseSession: &audioSession];            // starts timer suicide            [NSTimer scheduledTimerWithTimeInterval: kCallTimerSuicide                                             target: self                                           selector: @selector(timerSuicideTick:)                                           userInfo: nil                                            repeats: NO];//            [self performSelectorOnMainThread:@selector(closeView) withObject:nil waitUntilDone:NO];            break;        }    }}

谢谢啊如有不对还请指正！

最近在重整一个app 秉着开源精神放在github上（目前还在开发阶段不过每天会更新的）
