本文主要说的是ios客户端。服务端的默认已经构建好。
//主要的关键是://通过//-(void)xmppRoom:(XMPPRoom *)sender didReceiveMessage:(XMPPMessage *)message fromOccupant:(XMPPJID *)occupantJID//接收到消息////在该方法中调用代理方法//-(void)newMessageReceived:(NSDictionary *)message
1、下载xmppframework(googol一下就出来了)
2、导入到你的工程(参照github)
3、在AppDelegate中实现xmpp代理
-(void)setupStream{//初始化XMPPStreamxmppStream = [[XMPPStream alloc] init];[xmppStream addDelegate:self delegateQueue:dispatch_get_main_queue()];xmppPing = [[XMPPPing alloc]init];xmppPing.respondsToQueries = YES;[xmppPing activate:xmppStream];xmppReconnect = [[XMPPReconnect alloc]init];xmppReconnect.autoReconnect = YES;[xmppReconnect activate:xmppStream];}
(3)、登录xmpp消息服务器
//登录XMPP服务器-(BOOL)login:(NSString*)userid code:(NSString*)passcode{[self setupStream];if (![xmppStream isDisconnected]) {[self.chatDelegate didConnect];return YES;}NSString *server = ChatHost;//设置用户NSString *userId = [NSString stringWithFormat:@"%@@%@",userid,server];XMPPJID *jid = [XMPPJID jidWithString:userId];[xmppStream setMyJID:jid];//设置服务器[xmppStream setHostName:server];//密码password = passcode;NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];[defaults setObject:userid forKey:USER];[defaults setObject:passcode forKey:PSW];//连接服务器NSError *error = nil;if(![xmppStream connectWithTimeout:XMPPStreamTimeoutNone error:&error]){NSLog(@"cant connect %@", server);return NO;}return YES;}
（2)、初始化聊天室
-(void)initxmpproom{[self getrooms];xmppRoomStorage = [XMPPRoomCoreDataStorage sharedInstance];XMPPJID *roomJID = [XMPPJID jidWithString:CHATROOM];xmppRoom = [[XMPPRoom alloc] initWithRoomStorage:xmppRoomStorage jid:roomJID];[xmppRoom activate:xmppStream];[xmppRoom addDelegate:self delegateQueue:dispatch_get_main_queue()];//加入房间[self joinroom];}(3)、加入房间-(void)joinroom{NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];[xmppRoom joinRoomUsingNickname:[defaults stringForKey:USER] history:nil];}
(4)、有人在群里发言(实现代理方法)-(void)xmppRoom:(XMPPRoom *)sender didReceiveMessage:(XMPPMessage *)message fromOccupant:(XMPPJID *)occupantJID{NSLog(@"群发言了。。。。");NSString *type = [[message attributeForName:@"type"] stringValue];if ([type isEqualToString:@"groupchat"]) {NSString *msg = [[message elementForName:@"body"] stringValue];NSString *timexx = [[timex attributeForName:@"stamp"] stringValue];NSString *from = [[message attributeForName:@"from"] stringValue];NSMutableDictionary *dict = [NSMutableDictionary dictionary];[dict setObject:msg forKey:@"body"];[dict setObject:from forKey:@"from"];//消息委托[messageDelegate newMessageReceived:dict];}}(5)、新人加入群聊- (void)xmppRoom:(XMPPRoom *)sender occupantDidJoin:(XMPPJID *)occupantJID{NSLog(@"新人加入群聊");}(6)、有人退出群聊- (void)xmppRoom:(XMPPRoom *)sender occupantDidLeave:(XMPPJID *)occupantJID{NSLog(@"有人退出群聊");}
(7)、发送新的群聊消息
//发送群消息- (IBAction)sendPress:(UIButton *)sender {//本地输入框中的信息NSString *message = self.sendtextfield.text;self.sendtextfield.text = @"";[self.sendtextfield resignFirstResponder];if (message.length > 0){NSXMLElement *body = [NSXMLElement elementWithName:@"body"];[body setStringValue:message];//生成XML消息文档NSXMLElement *mes = [NSXMLElement elementWithName:@"message"];//消息类型[mes addAttributeWithName:@"type" stringValue:@"groupchat"];//发送给谁[mes addAttributeWithName:@"to" stringValue:CHATROOM];//由谁发送NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];[mes addAttributeWithName:@"from" stringValue:[NSString stringWithFormat:@"%@/%@",CHATROOM,[defaults stringForKey:USER]]];//组合[mes addChild:body];//发送消息[[app xmppStream] sendElement:mes];}}
(8)、
-(void)newMessageReceived:(NSDictionary *)messageContent{[arr1 addObject:messageContent];[self.tableview1 reloadData];if (self.tableview1.contentSize.height > self.tableview1.frame.size.height) {[self.tableview1 setContentOffset:CGPointMake(0, self.tableview1.contentSize.height – self.tableview1.frame.size.height)];}}
，悠然享受和大自然融合之乐。
