聊天页面一pop出来就会clearAllConversationMessages。这是怎么回事！！

需要查一下你代码中，在这个过程哪里执行了删除会话和消息的接口
1.
- (void)deleteConversation:(NSString *)aConversationId
isDeleteMessages:(BOOL)aIsDeleteMessages
completion:(void (^)(NSString *aConversationId, EMError *aError))aCompletionBlock;
2.
- (void)deleteConversations:(NSArray *)aConversations
isDeleteMessages:(BOOL)aIsDeleteMessages
completion:(void (^)(EMError *aError))aCompletionBlock;
3.
- (BOOL)deleteConversation:(NSString *)aConversationId
deleteMessages:(BOOL)aDeleteMessage;
4.
- (BOOL)deleteConversations:(NSArray *)aConversations
deleteMessages:(BOOL)aDeleteMessage;

这些接口都是主动调用的
