When i click on Meet now and Join a Meeting button App is not responding on UI & also not printing on Console.

MobileRTCMeetingService \*ms = [[MobileRTC sharedRTC] getMeetingService];&nbsp;

This is returning NULL when i debug this sample application. If anyone had faced this same issue do reply…

Hi Harinder,

did you check the return value by following approach:

"MobileRTCMeetError ret = [ms startMeetingWithDictionary:paramDict];

NSLog(@“onMeetNow ret:%d”, ret);"

Best

Hi Harinder

Do you check the auth is a success or not.

Success auth is the premise of everything.

Please check:

- (void)onMobileRTCAuthReturn:(MobileRTCAuthError)returnValue  
{  
NSLog(@“onMobileRTCAuthReturn %d”, returnValue);  
}

Thanks.
