어떻게 아래로는 IMAP 메일 서버를 연결해야 IBAction를 IOS

Question

에 BOOL를 사용하는 방법?

- (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"]; 
}

... 다른 방법으로 부르시겠습니까?

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