IOS基於XMPP協議開發－－XMPPFramewok框架（二）：服務器鏈接

 

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

　　　　　鏈接服務器必須進行JID設置，若是尚未帳號能夠設置任意值

　　

具體代碼以下：

- (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(@"鏈接失敗%@",error);
    }
    
    return YES;
}

 

鏈接返回的回調結果

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

 

斷開鏈接

 [_xmppStream disconnect];
