XMPPFramework - 消息未发送

技术标签:
【中文标题】XMPPFramework - 消息未发送【英文标题】：XMPPFramework - Message not sent 【发布时间】：2013-04-15 11:03:58 【问题描述】：我是ios 的新手。我正在使用XMPPFramework 构建一个应用程序。但是最近几天我遇到了一个问题。找不到任何解决方案。问题是当我想向任何特定 id 发送消息时，消息不会被发送。发送消息的动作方法是：
- (IBAction)sendMsg:(id)sender
xmppStream = [[XMPPStream alloc] init];
[xmppStream addDelegate:self delegateQueue:dispatch_get_main_queue()];
NSString *messageStr = self.msgField.text;
if ([messageStr length] > 0)
NSXMLElement *body = [NSXMLElement elementWithName:@"body"];
[body setStringValue:messageStr];
NSXMLElement *message = [NSXMLElement elementWithName:@"message"];
[message addAttributeWithName:@"type" stringValue:@"chat"];
[message addAttributeWithName:@"to" stringValue:@"abc.codemen@gmail.com"];
[message addChild:body];
[self.xmppStream sendElement:message];
这里是我的XMPPStream.m中发送NSXMLElement的sendElement方法：
- (void)sendElement:(NSXMLElement *)element
if (element == nil)
return;
dispatch_block_t block = ^ @autoreleasepool
if (state == STATE_XMPP_CONNECTED)
[self sendElement:element withTag:TAG_XMPP_WRITE_STREAM];
;
if (dispatch_get_current_queue() == xmppQueue)
block();
else
dispatch_async(xmppQueue, block);
但是我发现消息发送的方法调用没有进入if语句！
if (state == STATE_XMPP_CONNECTED)
[self sendElement:element withTag:TAG_XMPP_WRITE_STREAM];
我认为这就是为什么我不能向任何 id 发送消息的原因。请通过建议我是错还是对来帮助我，我该如何解决这个问题？

【问题讨论】：
【参考方案1】：如果您是 xmpp 框架的新手，那么您应该首先为聊天客户端设置服务器（如 Ejabbered、openfire），然后您必须对其进行配置以进行聊天。您将从以下链接中找到非常好的教程，该链接分为四个部分。请一步一步看这个教程：-

【讨论】：
谢谢兄弟。实际上我想为 gtalk 实现聊天功能。我可以用 Jabber 这样做吗？ @John 我没有用 gtalk 检查过，但我认为 gtalk 应该可以和 Jabber 一起使用 Sunil，如果我能知道我的代码有什么问题会更好，因为我已经从事该项目很多天了。而且由于我不确定如果我使用 jabber 是否可以使用 gmail id 和密码登录，所以我现在开始使用 Jabber 将非常耗时。如果我无法使用 gmail 凭据登录，那对我来说将更加可悲！不管怎么说，还是要谢谢你。投票给你。 @John 您目前使用的是哪台服务器？ 是的 Sunil，我已经下载了 xmpp 框架，并按照我在 github 中找到的方向来实现我的项目。以上是关于XMPPFramework - 消息未发送的主要内容，如果未能解决你的问题，请参考以下文章
