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.";

}

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:5222];

    //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];

}
