/*  发送消息的格式 
    
      　　Hello World! 
      */- (void)sendText:(NSString *)text toJid:(NSString *)jidString completion:(HYBCompletionBlock)completion {   self.sendMessageBlock = completion;     NSXMLElement *body = [NSXMLElement elementWithName:@"body"];  [body setStringValue:text];    NSXMLElement *message = [NSXMLElement elementWithName:@"message"];  [message addAttributeWithName:@"type" stringValue:@"chat"];     if (![jidString hasSuffix:kServer]) {     jidString = [NSString stringWithFormat:@"%@@%@", jidString, kServer];   }     [message addAttributeWithName:@"to" stringValue:jidString];  [message addChild:body];  [self.xmppStream sendElement:message];}
    

消息节点的结构是这样的：

    
      　　Hello World! 
     
    

- (void)xmppStream:(XMPPStream *)sender didSendMessage:(XMPPMessage *)message {  if (self.sendMessageBlock) {    self.sendMessageBlock(YES, nil);  }}- (void)xmppStream:(XMPPStream *)sender didFailToSendMessage:(XMPPMessage *)message error:(NSError *)error {  if (self.sendMessageBlock) {    self.sendMessageBlock(NO, [error description]);  }}

结束：

话不多说了，功能简单，高级功能就不深入了，等到有机会做相关项目时，再深入研究研究。
