问题描述
我写了一个用作服务器的程序. 知道接受"正在阻止程序. 我想使用此语句启动线程,以防止程序被阻止,但这仍然会发生. 有人可以帮忙吗? 邮政编码 谢谢
I wrote a program that worked as a server. Knowing that "accept" was blocking the program. I wanted to launch a thread with this statement to prevent precisely that the program blocked, but this still happens. Can anybody help? Post code Thanks
-(IBAction)Connetti{
if(switchConnessione.on){
int port = [fieldPort.text intValue];
labelStatus.text = [[NSString alloc] initWithFormat:@"Il Server è attivo"];
server_len = sizeof(server);
server.sin_family = AF_INET;
server.sin_port = htons((u_short)port);
server.sin_addr.s_addr = INADDR_ANY;
sd = socket (AF_INET, SOCK_STREAM, 0);
bind(sd, (struct sockaddr*)&server, sizeof(server));
listen(sd, 1);
[NSThread detachNewThreadSelector:@selector(startThreadAccept) toTarget:self withObject:nil];
}
else {
labelStatus.text = [[NSString alloc] initWithFormat:@"Server non attivo"];
switchChat.on = FALSE;
switchChat.enabled = FALSE;
}
}
-(void)startThreadAccept{
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc]init];
[self performSelectorOnMainThread:@selector(acceptConnection) withObject:nil waitUntilDone:NO];
[pool release];
}
-(void)acceptConnection{
new_sd = accept(sd, (struct sockaddr*)&server, &server_len);
labelStatus.text = [[NSString alloc] initWithFormat:@"Ho accettato una connessione:%d", new_sd];
switchChat.enabled = TRUE;
}
推荐答案
您仍然在主线程上调用accept()
.如果要在其他线程上接受连接,则需要删除-performSelectorOnMainThread:
调用.
You still call accept()
on the main thread. If you want the connection to be accepted on a different thread, then you need to remove the -performSelectorOnMainThread:
call.
