ios把服务器上的数据插到环信demo的数据库，出错了

消息数据要包成EMMessage对象，然后才能插入到db的。

怎么包装成EMMessage，是把我的字典数组转成模型吗，转成这个模型么，MessageModel *model？

http://www.easemob.com/docs/ios/IOSSDKMessage/#textalloc

我也是要这样写么，假如我保全上面的字典，有文字，图片，语音，视频等- (void)loadMessage

对的，你的消息数据要包成EMMessage对象，然后才能插入到db。

但我是上面字典一组数据，- (NSInteger)insertMessagesToDB:(NSArray *)messages;这个数组装的是EMMessage对象是不是，要不要把我的字典数组转成模型后在给EMMessage对象传值
