- (NSString *) getDNSServers
{
NSMutableString *addresses = [[NSMutableString alloc]initWithString:@"DNS Addresses \n"];
res_state res = malloc(sizeof(struct __res_state));
if ( result == 0 )
{
for ( int i = 0; i < res->nscount; i++ )
{
NSString *s = [NSString stringWithUTF8String : inet_ntoa(res->nsaddr_list[i].sin_addr)];
[addresses appendFormat:@"%@\n",s];
}
}
else
[addresses appendString:@" res_init result != 0"];
return addresses;
}
需要引入libresolv.tbd
