XMPP群聊消息重复，自己收到自己发出的消息，群警告消息如何屏蔽

在XMPP的"groupchat"中，创建群的时候会收到群发的"This room is locked from entry until configuration is confirmed."和"This room is now unlocked."警告，并且每次进群的时候都会收到"This room is not anonymous."警告，而且自己向群发的消息，每次群还会发回给我，看起来就像自己发给自己，造成消息重复。这些问题怎么解决？（问题截图如下）



实际上这些消息其他人也碰到过，群聊的时候会有各种配置项，如果不写配置，默认创建的是Instant room。群聊的时候，自己发给群一条消息，群会帮你广播给群里所有人，所以你收到自己发出的消息也是正常现象。如果你不想收到上述所有的警告，你需要修改"/XMPPFramework的/XMPPFramework/Extenstions/XEP-0136/XMPPMessageArchiving.m"这个路径的框架原文件。(红色的是修改添加的代码)。

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

XMPPJID *jid = message.from;
NSString *str = jid.resource;

//发给自己的消息会忽略
if ([str isEqualToString:kGlobal.userInfo.sApplyName]) {
return;
}

//群发的警告会忽略 This room is not anonymous.
if (message.childCount>=2) {
DDXMLElement *element = message.children[1];
if (element.childCount>0) {
DDXMLElement *subChild = element.children[0];
if (subChild.attributes.count>0) {
DDXMLNode *statusNode = subChild.attributes[0];
if ([statusNode.name isEqualToString:@"code"]&&[statusNode.stringValue isEqualToString:@"100"]) {
return;
}
}
}
}

//忽略群发警告 This room is locked from entry until configuration is confirmed.
if ([message.body isEqualToString:@"This room is locked from entry until configuration is confirmed."]) {
return;
}

//忽略群发警告 This room is now unlocked.
if ([message.body isEqualToString:@"This room is now unlocked."]) {
return;
}

if ([self shouldArchiveMessage:message outgoing:NO xmppStream:sender])
{
[xmppMessageArchivingStorage archiveMessage:message outgoing:NO xmppStream:sender];
}
}

改善后的截图如下：
