iOS的xmppframework簡介
因爲博客遷移至www.coderyi.com,文章請看http://www.coderyi.com/archives/436數據庫
1登陸和好友上下線
1.1XMPP中經常使用對象們
XMPPStream：xmpp基礎服務類服務器
XMPPRoster：好友列表類框架
XMPPRosterCoreDataStorage：好友列表（用戶帳號）在core data中的操做類dom
XMPPvCardCoreDataStorage：好友名片（暱稱，簽名，性別，年齡等信息）在core data中的操做類socket
XMPPvCardTemp：好友名片實體類，從數據庫裏取出來的都是它測試
xmppvCardAvatarModule：好友頭像fetch
XMPPReconnect：若是失去鏈接,自動重連spa
XMPPRoom：提供多用戶聊天支持代理
XMPPPubSub：發佈訂閱code
1.2登陸操做，也就是鏈接xmpp服務器
- (void)connect {
if (self.xmppStream == nil) {
self.xmppStream = [[XMPPStream alloc] init];
[self.xmppStream addDelegate:self delegateQueue:dispatch_get_main_queue()];
}
if (![self.xmppStream isConnected]) {
NSString *username = [[NSUserDefaults standardUserDefaults] objectForKey:@"username"];
XMPPJID *jid = [XMPPJID jidWithUser:username domain:@"lizhen" resource:@"Ework"];
[self.xmppStream setMyJID:jid];
[self.xmppStream setHostName:@"10.4.125.113"];
NSError *error = nil;
if (![self.xmppStream connect:&error]) {
NSLog(@"Connect Error: %@", [[error userInfo] description]);
}
}
}
connect成功以後
會依次調用XMPPStreamDelegate的方法，
首先調用
- (void)xmppStream:(XMPPStream *)sender socketDidConnect:(GCDAsyncSocket *)socket
而後
- (void)xmppStreamDidConnect:(XMPPStream *)sender
在該方法下面須要使用xmppStream 的authenticateWithPassword方法進行密碼驗證，成功的話會響應delegate的方法，就是下面這個
- (void)xmppStreamDidAuthenticate:(XMPPStream *)sender
1.3上線
實現 - (void)xmppStreamDidAuthenticate:(XMPPStream *)sender 委託方法
- (void)xmppStreamDidAuthenticate:(XMPPStream *)sender {
XMPPPresence *presence = [XMPPPresence presenceWithType:@"available"];
[self.xmppStream sendElement:presence];
}
1.4退出並斷開鏈接
- (void)disconnect {
XMPPPresence *presence = [XMPPPresence presenceWithType:@"unavailable"];
[self.xmppStream sendElement:presence];
[self.xmppStream disconnect];
}
1.5好友狀態
獲取好友狀態，經過實現
- (void)xmppStream:(XMPPStream *)sender didReceivePresence:(XMPPPresence *)presence
方法
當接收到 <presence /> 標籤的內容時，XMPPFramework 框架回調該方法
一個 <presence /> 標籤的格式通常以下：
<presence from=""> <show>這裏是顯示的內容<show /> <status>這裏是顯示的狀態<status /> <presence />
presence 的狀態：
available 上線
away 離開
do not disturb 忙碌
unavailable 下線
- (void)xmppStream:(XMPPStream *)sender didReceivePresence:(XMPPPresence *)presence {
NSString *presenceType = [presence type];
NSString *presenceFromUser = [[presence from] user];
if (![presenceFromUser isEqualToString:[[sender myJID] user]]) {
if ([presenceType isEqualToString:@"available"]) {
//
} else if ([presenceType isEqualToString:@"unavailable"]) {
//
}
}
}
2接收消息和發送消息
2.1接收消息
經過實現
- (void)xmppStream:(XMPPStream *)sender didReceiveMessage:(XMPPMessage *)message;
方法
當接收到 <message /> 標籤的內容時，XMPPFramework 框架回調該方法
根據 XMPP 協議，消息體的內容存儲在標籤 <body /> 內
- (void)xmppStream:(XMPPStream *)sender didReceiveMessage:(XMPPMessage *)message {
NSString *messageBody = [[message elementForName:@"body"] stringValue];
}
2.2發送消息
發送消息，咱們須要根據 XMPP 協議，將數據放到 <message /> 標籤內，例如：
<message type="chat" to="xiaoming@example.com"> <body>Hello World!<body /> <message />
- (void)sendMessage:(NSString *) message toUser:(NSString *) user {
NSXMLElement *body = [NSXMLElement elementWithName:@"body"];
[body setStringValue:message];
NSXMLElement *message = [NSXMLElement elementWithName:@"message"];
[message addAttributeWithName:@"type" stringValue:@"chat"];
NSString *to = [NSString stringWithFormat:@"%@@example.com", user];
[message addAttributeWithName:@"to" stringValue:to];
[message addChild:body];
[self.xmppStream sendElement:message];
}
3獲取好友信息和刪除好友
3.1好友列表和好友名片
[_xmppRoster fetchRoster];//獲取好友列表 //獲取到一個好友節點 - (void)xmppRoster:(XMPPRoster *)sender didRecieveRosterItem:(NSXMLElement *)item //獲取無缺友列表 - (void)xmppRosterDidEndPopulating:(XMPPRoster *)sender //到服務器上請求聯繫人名片信息 - (void)fetchvCardTempForJID:(XMPPJID *)jid; //請求聯繫人的名片，若是數據庫有就不請求，沒有就發送名片請求 - (void)fetchvCardTempForJID:(XMPPJID *)jid ignoreStorage:(BOOL)ignoreStorage; //獲取聯繫人的名片，若是數據庫有就返回，沒有返回空，併到服務器上抓取 - (XMPPvCardTemp *)vCardTempForJID:(XMPPJID *)jid shouldFetch:(BOOL)shouldFetch; //更新本身的名片信息 - (void)updateMyvCardTemp:(XMPPvCardTemp *)vCardTemp; //獲取到一盒聯繫人的名片信息的回調 - (void)xmppvCardTempModule:(XMPPvCardTempModule *)vCardTempModule didReceivevCardTemp:(XMPPvCardTemp *)vCardTemp forJID:(XMPPJID *)jid
3.2添加好友
//name爲用戶帳號
- (void)XMPPAddFriendSubscribe:(NSString *)name
{
//XMPPHOST 就是服務器名， 主機名
XMPPJID *jid = [XMPPJID jidWithString:[NSString stringWithFormat:@"%@@%@",name,XMPPHOST]];
//[presence addAttributeWithName:@"subscription" stringValue:@"好友"];
[xmppRoster subscribePresenceToUser:jid];
}
3.3收到添加好友的請求
- (void)xmppRoster:(XMPPRoster *)sender didReceivePresenceSubscriptionRequest:(XMPPPresence *)presence
{
//取得好友狀態
NSString *presenceType = [NSString stringWithFormat:@"%@", [presence type]]; //online/offline
//請求的用戶
NSString *presenceFromUser =[NSString stringWithFormat:@"%@", [[presence from] user]];
NSLog(@"presenceType:%@",presenceType);
NSLog(@"presence2:%@ sender2:%@",presence,sender);
XMPPJID *jid = [XMPPJID jidWithString:presenceFromUser];
//接收添加好友請求
[xmppRoster acceptPresenceSubscriptionRequestFrom:jid andAddToRoster:YES];
}
3.4刪除好友
//刪除好友，name爲好友帳號
- (void)removeBuddy:(NSString *)name
{
XMPPJID *jid = [XMPPJID jidWithString:[NSString stringWithFormat:@"%@@%@",name,XMPPHOST]];
[self xmppRoster] removeUser:jid];
}
4聊天室
//初始化聊天室
XMPPJID *roomJID = [XMPPJID jidWithString:ROOM_JID]; xmppRoom = [[XMPPRoom alloc] initWithRoomStorage:self jid:roomJID]; [xmppRoom activate:xmppStream]; [xmppRoom addDelegate:self delegateQueue:dispatch_get_main_queue()];
//建立聊天室成功
- (void)xmppRoomDidCreate:(XMPPRoom *)sender
{
DDLogInfo(@"%@: %@", THIS_FILE, THIS_METHOD);
}
//加入聊天室，使用暱稱 [xmppRoom joinRoomUsingNickname:@"quack" history:nil];
//獲取聊天室信息
- (void)xmppRoomDidJoin:(XMPPRoom *)sender
{
[xmppRoom fetchConfigurationForm];
[xmppRoom fetchBanList];
[xmppRoom fetchMembersList];
[xmppRoom fetchModeratorsList];
}
若是房間存在，會調用委託
// 收到禁止名單列表 - (void)xmppRoom:(XMPPRoom *)sender didFetchBanList:(NSArray *)items; // 收到好友名單列表 - (void)xmppRoom:(XMPPRoom *)sender didFetchMembersList:(NSArray *)items; // 收到主持人名單列表 - (void)xmppRoom:(XMPPRoom *)sender didFetchModeratorsList:(NSArray *)items;
房間不存在，調用委託
- (void)xmppRoom:(XMPPRoom *)sender didNotFetchBanList:(XMPPIQ *)iqError; - (void)xmppRoom:(XMPPRoom *)sender didNotFetchMembersList:(XMPPIQ *)iqError; - (void)xmppRoom:(XMPPRoom *)sender didNotFetchModeratorsList:(XMPPIQ *)iqError;
離開房間
[xmppRoom deactivate:xmppStream];
XMPPRoomDelegate的其餘代理方法
//離開聊天室
- (void)xmppRoomDidLeave:(XMPPRoom *)sender
{
DDLogVerbose(@"%@: %@", THIS_FILE, THIS_METHOD);
}
//新人加入羣聊
- (void)xmppRoom:(XMPPRoom *)sender occupantDidJoin:(XMPPJID *)occupantJID
{
DDLogVerbose(@"%@: %@", THIS_FILE, THIS_METHOD);
}
//有人退出羣聊
- (void)xmppRoom:(XMPPRoom *)sender occupantDidLeave:(XMPPJID *)occupantJID
{
DDLogVerbose(@"%@: %@", THIS_FILE, THIS_METHOD);
}
//有人在羣裏發言
- (void)xmppRoom:(XMPPRoom *)sender didReceiveMessage:(XMPPMessage *)message fromOccupant:(XMPPJID *)occupantJID
{
DDLogVerbose(@"%@: %@", THIS_FILE, THIS_METHOD);
}
5消息回執
這個是XEP－0184協議的內容
協議內容：
發送消息時附加回執請求
<message from='northumberland@shakespeare.lit/westminster' id='richard2-4.1.247' to='kingrichard@royalty.england.lit/throne'> <body>My lord, dispatch; read o'er these articles.</body> <request xmlns='urn:xmpp:receipts'/> </message>
代碼實現
NSString *siID = [XMPPStream generateUUID]; //發送消息 XMPPMessage *message = [XMPPMessage messageWithType:@"chat" to:jid elementID:siID]; NSXMLElement *receipt = [NSXMLElement elementWithName:@"request" xmlns:@"urn:xmpp:receipts"]; [message addChild:receipt]; [message addBody:@"測試"]; [self.xmppStream sendElement:message];
收到回執請求的消息，發送回執
<message from='kingrichard@royalty.england.lit/throne' id='bi29sg183b4v' to='northumberland@shakespeare.lit/westminster'> <received xmlns='urn:xmpp:receipts' id='richard2-4.1.247'/> </message>
代碼實現
- (void)xmppStream:(XMPPStream *)sender didReceiveMessage:(XMPPMessage *)message
{
//回執判斷
NSXMLElement *request = [message elementForName:@"request"];
if (request)
{
if ([request.xmlns isEqualToString:@"urn:xmpp:receipts"])//消息回執
{
//組裝消息回執
XMPPMessage *msg = [XMPPMessage messageWithType:[message attributeStringValueForName:@"type"] to:message.from elementID:[message attributeStringValueForName:@"id"]];
NSXMLElement *recieved = [NSXMLElement elementWithName:@"received" xmlns:@"urn:xmpp:receipts"];
[msg addChild:recieved];
//發送回執
[self.xmppStream sendElement:msg];
}
}else
{
NSXMLElement *received = [message elementForName:@"received"];
if (received)
{
if ([received.xmlns isEqualToString:@"urn:xmpp:receipts"])//消息回執
{
//發送成功
NSLog(@"message send success!");
}
}
}
//消息處理
//...
}
6添加AutoPing
爲了監聽服務器是否有效，增長心跳監聽。用XEP-0199協議，在XMPPFrameWork框架下，封裝了 XMPPAutoPing 和 XMPPPing兩個類均可以使用，由於XMPPAutoPing已經組合進了XMPPPing類，因此XMPPAutoPing使用起來更方便。
//初始化並啓動ping
-(void)autoPingProxyServer:(NSString*)strProxyServer
{
_xmppAutoPing = [[XMPPAutoPingalloc] init];
[_xmppAutoPingactivate:_xmppStream];
[_xmppAutoPingaddDelegate:selfdelegateQueue: dispatch_get_main_queue()];
_xmppAutoPing.respondsToQueries = YES;
_xmppAutoPing.pingInterval=2;//ping 間隔時間
if (nil != strProxyServer)
{
_xmppAutoPing.targetJID = [XMPPJID jidWithString: strProxyServer ];//設置ping目標服務器，若是爲nil,則監聽socketstream當前鏈接上的那個服務器
}
}
//卸載監聽
[_xmppAutoPing deactivate];
[_xmppAutoPing removeDelegate:self];
_xmppAutoPing = nil;
//ping XMPPAutoPingDelegate的委託方法:
- (void)xmppAutoPingDidSendPing:(XMPPAutoPing *)sender
{
NSLog(@"- (void)xmppAutoPingDidSendPing:(XMPPAutoPing *)sender");
}
- (void)xmppAutoPingDidReceivePong:(XMPPAutoPing *)sender
{
NSLog(@"- (void)xmppAutoPingDidReceivePong:(XMPPAutoPing *)sender");
}
- (void)xmppAutoPingDidTimeout:(XMPPAutoPing *)sender
{
NSLog(@"- (void)xmppAutoPingDidTimeout:(XMPPAutoPing *)sender");
}
