- (BOOL) connectToHost: (NSString*) hostname

    socket_ = socket(AF_INET, SOCK_STREAM, 0);
    if (socket_ < 0) {
        NSLog(@"socket");
    }

    struct sockaddr_in addr;
    memset(&addr, 0, sizeof(addr));
    addr.sin_family = AF_INET;
    addr.sin_port = htons(993);

    struct hostent* host = gethostbyname([hostname UTF8String]);
    unsigned int** ptr = (unsigned int **) host->h_addr_list;
    while (*ptr != NULL) {
        addr.sin_addr.s_addr = *(*ptr);

        if (connect(socket_, (struct sockaddr *) &addr, sizeof(addr)) == 0) {
            break;
        }

        ptr++;
    }
    if (*ptr == NULL) {
        NSLog(@"connect");
    }

    return [[self readLine] isEqualToString: @"* OK"];
}

Answer 1

… call it from another method?

- (IBAction) connectButtonClicked:(id)sender {
    [self connectToHost:@"Your host name goes here, variable _or_ constant! :D"];
}
