XMPP得知－－建立一个管理类

参考其他demo之后，设立一个管理类的发现看起来更舒服，理……

但在建立与server连接其中。发现

Connect Error: {

    NSLocalizedDescription = "You must set myJID before calling connect.";

}

这种一个问题。知道是jid没有设置好，可是jid怎么设置呢？今天仍然没有弄清。假设有清楚的能够交流一下。

1.将管理类写成单例

static
XmppManager *shareManager =
Nil;

+ (XmppManager *)shareInstance

{

static dispatch_once_t onceToken;

dispatch_once(&onceToken, ^{

shareManager = [[XmppManager
alloc]
init];

[shareManager
setupXMPPStream];

});

return
shareManager;

}

2.建立XML流，确定代理方法

- (void)setupXMPPStream

{

xmppStream = [[XMPPStream
alloc]
init];

#if !TARGET_OS_IPHONE

//非模拟器时可进入后台工作

xmppStream.enableBackgroundingOnSocket =
YES;

#endif

//代理

[xmppStream
addDelegate:self
delegateQueue:dispatch_get_main_queue()];

[xmppStream
setHostName:kXMPPHost];

[xmppStream
setHostPort];

//又一次连接

reconnect = [[XMPPReconnect
alloc]
init];

//花名冊

XMPPRosterCoreDataStorage *rosterStorage = [[XMPPRosterCoreDataStorage
alloc]
initWithInMemoryStore];

roster = [[XMPPRoster
alloc] initWithRosterStorage:rosterStorage];

[roster
addDelegate:self
delegateQueue:dispatch_get_main_queue()];

[reconnect
activate:xmppStream];

[roster
activate:xmppStream];

allowSSLHostNameMismatch =
YES;

allowSelfSignedCertificates =
YES;

}

3.在dealloc消除XML流

- (void)dealloc

{

[self
setoutXMPPStream];

}

- (void)setoutXMPPStream

{

[xmppStream
removeDelegate:self];

[reconnect
deactivate];

[roster
deactivate];

[xmppStream
disconnect];

xmppStream =
Nil;

reconnect =
Nil;

roster = Nil;

}

4.写用户的各种状态：上线，离线，离开。勿扰…..

#pragma mark -
用户状态

/*

presence
的状态：

available
上线

away 离开

do not disturb
忙碌

unavailable
下线

*/

- (void)goonline

{

XMPPPresence *presence = [XMPPPresence
presenceWithType:@"available"];

[xmppStream
sendElement:presence];

}

- (void)gooffline

{

XMPPPresence *presence = [XMPPPresence
presenceWithType:@"unavailable"];

[xmppStream
sendElement:presence];

}

- (void)away

{

XMPPPresence *presence = [XMPPPresence
presenceWithType:@"away"];

[xmppStream
sendElement:presence];

}

- (void)busy

{

XMPPPresence *presence = [XMPPPresence
presenceWithType:@"do not disturb"];

[xmppStream
sendElement:presence];

}

5.写用户的各种操作：加入好友，删除好友，发送消息

#pragma mark -
用户操作

//添加成员

- (void)addSomeBody:(NSString *)userId

{

[roster
subscribePresenceToUser:[XMPPJID
jidWithString:[NSString
stringWithFormat:@"%@@qq.com",userId]]];

}

//删除好友

- (void)deleteSomeBody:(NSString *)userId

{

[roster
unsubscribePresenceFromUser:[XMPPJID
jidWithString:[NSString
stringWithFormat:@"%@@qq.com",userId]]];

}

//发送消息

- (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:@"%@@qq.com", user];

[message_ addAttributeWithName:@"to"
stringValue:to];

[message_
addChild:body];

[xmppStream
sendElement:message_];

}

6.还有系统操作

#pragma mark -
系统操作

- (BOOL)connect

{

if (![xmppStream
isDisconnected]) {

return YES;

}

NSString *user = [[NSUserDefaults
standardUserDefaults] stringForKey:kXMPPmyJID];

NSString *password = [[NSUserDefaults
standardUserDefaults] stringForKey:kXMPPmyPassword];

XMPPJID *jid = [XMPPJID
jidWithUser:user domain:@""
resource:@""];

[xmppStream
setMyJID:jid];

passWord = password;

return
YES;

}

- (void)disconnect

{

[self
gooffline];

[xmppStream
disconnect];

}
