Monitoring Participant Events
Using the Client SDK, you can easily monitor participant related events in a conference call.
For monitoring events related to the conference CSParticipant (e.g., new participants joining the conference or participants dropping from the conference), you can define an object that implements the <CSConferenceDelegate> protocol.
Implement CSConferenceDelegate protocol
To monitor participants joining or leaving a conference, implement the <CSConferenceDelegate> protocol for the CSConference object. The method conference:participantsDidChange:changedParticipants: provides notifications whenever there is a change in the list of the active participants (CSActiveParticipant).
@interface AppConferenceHandler()
...
@end
@implementation AppConferenceHandler
- (void) conference: (CSConference*) conference
participantsDidChange: (CSDataCollectionChangeType) changeType
changedParticipants: (NSArray*) changedParticipants {
// Called to report that there is a change in the list of the
// active participants. CSDataCollectionChangeType indicates the type
// of changes in the list (i.e. added, updated, deleted or cleared).
switch (changedType) {
case CSDataCollectionChangeTypeAdded:
case CSDataCollectionChangeTypeUpdated:
case CSDataCollectionChangeTypeDeleted:
// The changedParticipants is an array of CSActiveParticipant
// objects that have changed.
// Add code to update application UI for added/updated/deleted
// participants.
break;
case CSDataCollectionChangeTypeCleared:
// Add code to remove all the previous participant information
// from the UI application.
break;
}
}
...
@end
To monitor changing of active participants for the conference, instantiate a conference handler (AppConferenceHandler) and add it as a delegate to the CSConference object.
AppConferenceHandler* conferenceHandler = [[AppConferenceHandler alloc] init];
call.conference.delegate = conferenceHandler;
