Gvoice iOS接入

 最近项目需要接入实时语音，然后就是接入的腾讯的Gvoice语音。

 其实GVoice接入很简单把官方的demo下载，然后把APPID（gameID） 和 APPkey 替换，代码直接搬过来用就行了。

1. 在这里值得一说的是，在接入语音遇到的问题，一个是测试的时候语音有回音，只需要把两台设备离远点就没有了。

2.在GVoice开启Mic的时候可能导致程序崩溃,是因为设备没有开启权限。解决办法直接做一个mic的权限判断，如果没有开启权限就不要去调用开启mic的方法。

3.在实力化GVoice的时候需要传入一个openID，最开始我是用的登录的token，然后发现在加入房间的时候会报错，我估计是因为token的字符太长了，然后我换成用户ID就好了。

这个是我自己封装的处理实时语音的类

#import <UIKit/UIKit.h>#import "GVoice.h"@interface GVoiceManager : UIViewController+ (GVoiceManager *) shareManger;/** 第三方初始化 必须初始化*/- (void) GVoiceinite;/** 加入房间*/- (void) joinRoom:(NSString *)roomID;/** 开始发语音，结束发语音*/- (void) openMic:(BOOL)isopen;/** 开启声音，关闭声音*/- (void) openSpeaker:(BOOL) isopen;/** 退出房间 */- (void) quitRoom;
