我并不是一个老板,但我对你的问题感到奇怪,因此,我对你们的问题进行了思考。
我发现这一页:。 www.un.org/Depts/DGACM/index_spanish.htm
该法典:
- (void)sendcmd:(NSString*)cmd {
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
NSString *hostname= [defaults stringForKey:@"hostname"];
NSHost *host=[NSHost hostWithName:hostname];
if (host) {
struct sockaddr_in addr;
int sockfd;
// Create a socket
sockfd = socket( AF_INET, SOCK_STREAM, 0 );
addr.sin_family = AF_INET;
addr.sin_addr.s_addr = inet_addr([[host address] UTF8String]);
addr.sin_port = htons( 2001 );
int conn = connect(sockfd, &addr, sizeof(addr));
if (!conn) {
NSData* data = [cmd dataUsingEncoding:NSISOLatin1StringEncoding];
ssize_t datasend = send(sockfd, [data bytes], [data length], 0);
datasend++;
//ssize_t send(int, const void *, size_t, int) __DARWIN_ALIAS_C(send);
close(sockfd);
} else {
// create a popup here!
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:[@"Connection failed to host " stringByAppendingString:hostname] message:@"Please check the hostname in the preferences." delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
[alert show];
[alert release];
}
} else {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:[@"Could not look up host " stringByAppendingString:hostname] message:@"Please check the hostname in the preferences." delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
[alert show];
[alert release];
}
}
一位海报还提出这一图书馆:entropydb - SocketWrapper
