iOS语音聊天的问题, 有哪位大神耐心求教

只要获取到这条语音消息，下载语音后，调用该方法即可，// 播放音频
- (void)asyncPlayingWithPath:(NSString *)aFilePath
                  completion:(void(^)(NSError *error))completon{

你要想在任何页面收听语音消息，首先你要有这条语音消息，然后在点击的时候直接简单粗暴的调用以下代码就行。
至于EMCDDeviceManager这个类是环信封装的一个第三方开源类，在官方开源代码里能找到

-(void)audioAction:(EMMessage *)aMessage

{

    id <IEMFileMessageBody> body = [aMessage.messageBodies firstObject];

    EMAttachmentDownloadStatus downloadStatus = [body attachmentDownloadStatus];

    if (downloadStatus == EMAttachmentDownloading) {

        //正在下载，请稍等

        return;

    }

    else if (downloadStatus == EMAttachmentDownloadFailure)

    {

        //下载失败，重新下载

        [[EaseMob sharedInstance].chatManager asyncFetchMessage:aMessage

 progress:nil];

        

        return;

    }

    

    if (body.messageBodyType == eMessageBodyType_Voice) {

        //开启红外线检测

        [[EMCDDeviceManager sharedInstance] enableProximitySensor];

        //播放语音

        EMChatVoice *chatVoice = (EMChatVoice *)((EMVoiceMessageBody *)body).chatObject;

        [[EMCDDeviceManager sharedInstance] asyncPlayingWithPath:

aMessage.chatVoice.localPath completion:^(NSError *error) {

                dispatch_async(dispatch_get_main_queue(), ^{

                    //关闭红外线检测

                    [[EMCDDeviceManager sharedInstance] disableProximitySensor];

            });

        }];

    }

}
