大家好，又见面了，我是全栈君

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: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];
}
