                                     isMsgDestruct:YES
                                         onSuccess:^(NSString * _Nullable data) {
                                             NSLog(@"setConversationIsMsgDestruct success");
                                         }
                                         onFailure:^(NSInteger code, NSString *message) {
                                             NSLog(@"setConversationIsMsgDestruct failed: %ld %@", (long)code, message);
                                         }];

Return value

The onSuccess callback returns confirmation when the operation succeeds.

State changes after the call

1. Local state update: The conversation's isMsgDestruct attribute is updated locally and synchronized with the backend.
2. Event notification: Updated conversation properties are broadcast via the onConversationChanged: delegate callback. Match items by conversationID to update local state and toggle controls.
3. Re-query calibration: This switch controls server-side message retention, which functions independently from client-side burn-after-reading. The actual duration before deletion is configured using Set the server-side message deletion period. For conversation listener setup, refer to Retrieve conversation list.
