IOS基于XMPP协议开发－－XMPPFramewok框架（二）：服务器连接

 

连接服务器前需准备事项：

1.搭建好XMPP服务器

2.设置服务器地址和端口  

[_xmppStream setHostName:@"127.0.0.1"];

[_xmppStream setHostPort:5222];

3.调用connect

 

关键项：

　　JID－格式必须为 "用户名"+"@"+"服务器地址",示例 :[email protected]

　　　　　连接服务器必须进行JID设置，如果还没有账号可以设置任意值

　　

具体代码如下：

- (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(@"连接失败%@",error);

    }

    

    return YES;

}

 

连接返回的回调结果

///连接成功

- (void)xmppStreamDidConnect:(XMPPStream *)sender

{

    NSLog(@"连接成功");

    isXmppConnected = YES;

    if(_isLogined){

        NSError *error = nil;

        if (![[self xmppStream] authenticateWithPassword:password error:&error])

        {

            NSLog(@"Error authenticating: %@", error);

        }

    }

}

///连接失败

- (void)xmppStreamDidDisconnect:(XMPPStream *)sender withError:(NSError *)error

{

    NSLog(@"连接断开");

    

    if (!isXmppConnected)

    {

        //DDLogError(@"Unable to connect to server. Check xmppStream.hostName");

    }

}

 

断开连接

 [_xmppStream disconnect];
