串連伺服器前需準備事項：

1.搭建好XMPP伺服器

2.設定伺服器位址和連接埠  

[_xmppStream setHostName:@"127.0.0.1"];

[_xmppStream setHostPort:5222];

3.調用connect

 

關鍵項：

　　JID－格式必須為 "使用者名稱"+"@"+"伺服器位址",樣本 :[email protected]

　　　　　串連伺服器必須進行JID設定，如果還沒有帳號可以設定任意值

　　

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(@"串連失敗%@",error);    }        return YES;}

 

串連返回的回調結果

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

 

中斷連線

 [_xmppStream disconnect];
