加入会议

调用MeetingServiceAPI接口加入会议joinMeeting

YealinkSDKMeetingService *ms = [[YealinkSDK shared] getMeetingService]
;
if (ms) {
YealinkSDKJoinMeetingParam * joinParam = [[YealinkSDKJoinMeetingParam
joinParam.userName = @"kSDKUserName";
joinParam.meetingNumber = meetingNo;
joinParam.password = pwd;
joinParam.isOpenAudio = YES;
joinParam.isOpenVideo = YES;
[ms joinMeetingWithParam:joinParam];
}

当状态是会议中时，就可以调用iOSapi将会议窗口嵌入到目标窗口中了

等待会议状态变化通知，判断委托YealinkSDKMeetingServiceDelegate实际上会议加入

结果，其他会议功能接口都需要在会议中的状态下才可以使用：

/*!

@brief Specified Meeting Errors.
@param error Internal error code.
@param message The message for meeting errors.
*/
