連接服務器前需準備事項：

1.搭建好XMPP服務器

2.設置服務器地址和端口

[_xmppStream setHostName:@"127.0.0.1"];

[_xmppStream setHostPort:5222];

3.調用connect

關鍵項：

　　JID－格式必須為 "用戶名"+"@"+"服務器地址",示例 :user@127.0.0.1

　　　　　連接服務器必須進行JID設置，如果還沒有賬號可以設置任意值

具體代碼如下：

- (BOOL)connect:(NSString*)user withpassWord:(NSString*)pwd{  

if (user != nil) {    user = [NSString stringWithFormat:@"%@@%@",user,_xmppStream.hostName];    }    if (![_xmppStream isDisconnected]) {        if(_isLogined){            NSError *error = nil;            password=pwd;            [[self xmppStream] setMyJID:[XMPPJID jidWithString:user  resource:@"ios"]];            if (![[self xmppStream] authenticateWithPassword:password error:&error])            {                NSLog(@"Error authenticating: %@", error);            }        }        return YES;    }    NSString *myJID = user;    NSString *myPassword = pwd;        if ( myPassword != nil) {        password = myPassword;    }    if (myJID != nil) {            [_xmppStream setMyJID:[XMPPJID jidWithString:myJID resource:@"ios"]];    }else{        [_xmppStream setMyJID:[XMPPJID jidWithString:_xmppStream.hostName resource:@"ios"]];    }    NSError *error = nil;    [_xmppStream connectWithTimeout:10 error:&error];    if(error)    {        NSLog(@"連接失敗%@",error);    }        return YES;}

連接返回的回調結果

///連接成功- (void)xmppStreamDidConnect:(XMPPStream *)sender{    NSLog(@"連接成功");    isXmppConnected = YES;    if(_isLogined){        NSError *error = nil;        if (![[self xmppStream] authenticateWithPassword:password error:&error])        {            NSLog(@"Error authenticating: %@", error);        }    }}///連接失敗- (void)xmppStreamDidDisconnect:(XMPPStream *)sender withError:(NSError *)error{    NSLog(@"連接斷開");        if (!isXmppConnected)    {        //DDLogError(@"Unable to connect to server. Check xmppStream.hostName");    }}
