Hi, I have a problem with my socket program. I create the client program (my code is below) I have a problem when i close the socket with the disconnect method. Can i help me? Thanks and sorry for my English XP
CFSocketRef s;
-(void)CreaConnessione
{
CFSocketError errore;
struct sockaddr_in sin;
CFDataRef address;
CFRunLoopSourceRef source;
CFSocketContext context = { 0, self, NULL, NULL, NULL };
s = CFSocketCreate(
NULL,
PF_INET,
SOCK_STREAM,
IPPROTO_TCP,
kCFSocketDataCallBack,
AcceptDataCallback,
&context);
memset(&sin, 0, sizeof(sin));
int port = [fieldPorta.text intValue];
NSString *tempIp = fieldIndirizzo.text;
const char *ip = [tempIp UTF8String];
sin.sin_family = AF_INET;
sin.sin_port = htons(port);
sin.sin_addr.s_addr = (long)inet_addr(ip);
address = CFDataCreate(NULL, (UInt8 *)&sin, sizeof(sin));
errore = CFSocketConnectToAddress(s, address, 0);
if(errore == 0){
buttonInvioMess.enabled = TRUE;
fieldMessaggioInvio.enabled = TRUE;
labelTemp.text = [NSString stringWithFormat:@"Connesso al Server"];
CFRelease(address);
source = CFSocketCreateRunLoopSource(NULL, s, 0);
CFRunLoopAddSource(CFRunLoopGetCurrent(),
source,
kCFRunLoopDefaultMode);
CFRelease(source);
CFRunLoopRun();
}
else{
labelTemp.text = [NSString stringWithFormat:@"Errore di connessione. Verificare Ip e Porta"];
switchConnection.on = FALSE;
}
}
//the socket doesn't disconnect
-(void)Disconnetti{
CFSocketInvalidate(s);
CFRelease(s);
}
-(IBAction)Connetti
{
if(switchConnection.on)
[self CreaConnessione];
else
[self Disconnetti];
}
