XMPPFramework是一個OS X/iOS平臺的開源項目,使用Objective-C實現了XMPP協議(RFC-3920),同時還提供了用於讀寫XML的工具,大大簡化了基於XMPP的通訊應用的開發。git
1. 登陸和好友上下線github
1.1XMPP中經常使用對象們數據庫
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工具
xmppvCardAvatarModule:好友頭像測試
XMPPReconnect:若是失去鏈接,自動重連fetch
XMPPRoom:提供多用戶聊天支持
XMPPPubSub:發佈訂閱
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
1
2
3
|
- (void)xmppStream:(XMPPStream *)sender socketDidConnect:(GCDAsyncSocket *)socket
...
|
而後
1
|
- (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
1
|
- (void)xmppStreamDidAuthenticate:(XMPPStream *)sender
|
1.3上線
實現 - (void)xmppStreamDidAuthenticate:(XMPPStream *)sender 委託方法
1

4
|
- (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
1
2
3
|
- (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 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
1
|
- (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
1
2
3
|
- (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,將數據放到標籤內,例如:
1
2
3
4
5
6
7
8
9
10
|
- (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];
}
|

//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

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。
