检查当前会议是否已在Zoom Cloud SDK中进行

Question

嗨，我正在使用Zoom iOS SDK进行视频会议，

https://marketplace.zoom.us/docs/sdk/sdk-reference/ios-reference

我想在开始视频通话之前检查当前主持人（Some MeetingID：3094 ******），如果主持人正忙于其他呼叫，如何断开呼叫。

我正在模仿这样的呼叫

 if let meetingSesrvice = MobileRTC.shared()?.getMeetingService()
        {

          meetingSesrvice.delegate = self
          let dicParams = [kMeetingParam_Username:"Dhiraj kumar",
                                                    kMeetingParam_MeetingNumber:"3094******",
                                                    kMeetingParam_MeetingPassword:""]

           meetingSesrvice.joinMeeting(with: dicParams)
        }

请帮助
