How to Register With DNS
Hello,
I'm Developing an VOIP app in iOS, I'm trying to register with domain or
IP, Its working fine. While trying to connect with DNS to my SIP server, it
giving errors. At my code part it write as below.
//Here dns is DNS domain name like example.com
dns = [[NSUserDefaults standardUserDefaults] stringForKey: @"dnsServer"];
array = [dns componentsSeparatedByString:@","];
NSEnumerator *enumerator = [array objectEnumerator];
NSString *anObject;
unsigned i;
char line[128];
Boolean result;
CFHostRef hostRef;
NSString *hostname = dns;
NSMutableArray *tempDNS = [[NSMutableArray alloc] init];
CFArrayRef addresses = NULL;
hostRef = CFHostCreateWithName(kCFAllocatorDefault, (__bridge CFStringRef
)hostname);
if (hostRef) {
result = CFHostStartInfoResolution(hostRef, kCFHostAddresses, NULL);
if (result == TRUE) {
addresses = CFHostGetAddressing(hostRef, &result);
for(int i = 0; i < CFArrayGetCount(addresses); i++){
struct sockaddr_in* remoteAddr;
CFDataRef saData = (CFDataRef)CFArrayGetValueAtIndex(addresses,
i);
remoteAddr = (struct sockaddr_in*)CFDataGetBytePtr(saData);
if(remoteAddr != NULL){
// Extract the ip address
//const char *strIP41 = inet_ntoa(remoteAddr->sin_addr);
NSString *strDNS =[NSString stringWithCString:inet_ntoa
(remoteAddr->sin_addr) encoding:NSASCIIStringEncoding];
//Our DNS returns 2 name server
NSLog(@"RESOLVED %d:<%@>", i, strDNS);
[tempDNS addObject:strDNS];//here I'm adding IP address to
an array.
}
}
}
}
while (anObject = [enumerator nextObject])
{
NSMutableString *mutableStr = [anObject mutableCopy];
CFStringTrimWhitespace((CFMutableStringRef)mutableStr);
srv = [mutableStr UTF8String];
if (srv && strlen(srv))
{
if (app_config->cfg.nameserver_count==PJ_ARRAY_SIZE(app_config->cfg.
nameserver))
{
PJ_LOG(1,(THIS_FILE, "Error: too many DNS servers"));
[mutableStr release];
break;
}
for (i=0; i<app_config->cfg.nameserver_count; ++i) {
pj_ansi_sprintf(line, "--nameserver %.*s\n",(int)app_config->cfg.
nameserver[i].slen,app_config->cfg.nameserver[i].ptr);
// pj_strcat2(&cfg, line);
}
pj_strdup2_with_null(app_config->pool, &(app_config->cfg.nameserver
[app_config->cfg.nameserver_count++]), srv);
}
[mutableStr release];
}
I'm getting response like below. Any one please guide me, How to work with
DNS. Sample code would appreciate.
