Converting [NSNetservice addresses] to ip address string
cocoa-touch, iphone, nsnetservice, objective-c
Solution
If you're getting implicit declaration of inet_ntoa, you probably need
#include <arpa/inet.h>
(You can man inet_ntoa to get this info and read more about that function)
Problem
This question was already asked here: NSNetservice IP address and here: iPhone: Bonjour NSNetService IP address and port I've used both of those to get where I'm at now. My problem is the following method I have doesn't quite work: ``` - (NSString *)getStringFromAddressData:(NSData *)dataIn { struct sockaddr_in *socketAddress = nil; NSString *ipString = nil; socketAddress = (struct sockaddr_in *)[dataIn bytes]; ipString = [NSString stringWithFormat: @"%s", inet_ntoa(socketAddress->sin_addr)]; ///problem here return ipString; } ``` This gives a build error saying both "Dereferencing pointer to incomplete type" and "Implicit declaration of function 'inet_ntoa'" on the same line. I've checked and I don't think I'm missing some type of framework to get `inet_ntoa` to work. Any idea what I'm doing wrong? thanks.
