xmpp这一段蛋疼的 坑，

1，注释的地方 如果放出来，会 出现发送两遍消息的错觉，

2，并且消息的 id有一模一样的，如果 刚好用这个做 id的话 会出现 主键约束，而 离线消息只能插入一条的情况，

- (void)xmppStream:(XMPPStream *)sender didReceiveMessage:(XMPPMessage *)message

{

    TTLog(@"receive message -----------------%@",message);

    IMMessageInfo *iMessageInfo = [[IMRootManagershareManager]xmppMessageToChatMessage:message stateFlag:RECEIVE_SUCCESS];

    [[DBcontrolsharedDBControl] saveIMMessage:iMessageInfo];

    

    NSDictionary *userInfo = [NSDictionary dictionaryWithObjectsAndKeys:message, IM_MESSAGE_BODY, nil];

    [[NSNotificationCenterdefaultCenter] postNotificationName:IM_MESSAGE_RECEIVEobject:selfuserInfo:userInfo];

    

    if([UIApplicationsharedApplication].applicationState == UIApplicationStateBackground){

        [selfpushLocalNotification:message];

    }

//    if([message hasReceiptRequest]){

//        XMPPMessage *responseMessage = [message generateReceiptResponse];

//        NSXMLElement *body = [NSXMLElement elementWithName:@"body"];

//        [body setStringValue:@"r"];

//        [responseMessage addChild:body];

//        [xmppStream sendElement:responseMessage];

//    }

    if ([message isChatMessageWithBody]) {

        NSString *messageID = [ChatVoiceRecorderVC getCurrentTimeString];

        [message addAttributeWithName:@"id" stringValue:messageID];

        TTLog(@" message with id-----------------%@",message);

 

      

    }
