升级环信3.2 从数据库获取指定数量的消息

将老方法替换了旧的* \~chinese

* 从数据库获取指定数量的消息，取到的消息按时间排序，并且不包含参考的消息，如果参考消息的ID为空，则从最新消息向前取

*

* @param aMessageId 参考消息的ID

* @param aLimit 获取的条数

* @param aDirection 消息搜索方向

*

* @result 消息列表

*

* \~english

* Get more messages from DB, result messages are sorted by receive time, and NOT include the reference message, if reference messag's ID is nil, will fetch message from latest message

*

* @param aMessageId Reference message's ID

* @param aLimit Count of messages to load

* @param aDirection Message search direction

*

* @result Message list

*/

- (NSArray *)loadMoreMessagesFromId:(NSString *)aMessageId

limit:(int)aLimit

direction:(EMMessageSearchDirection)aDirection __deprecated_msg("Use -loadMessagesStartFromId:count:searchDirection:completion:");

获取消息记录就崩啦。
