How to get the external ip in Objective-C
cocoa-touch, ios, iphone, objective-c
Solution
The easiest way to get your internet ip address from code is to use NSURLConnection.
For the URL you can use: http://www.whatismyip.com/m/mobile.asp or http://checkip.dyndns.com/
Just parse the return data and you have your external ip address.
Problem
I looked for some code that will help me to get the ip that the iPhone connect with. I find this one: ``` - (NSString *)getIPAddress { NSString *address = @"error"; struct ifaddrs *interfaces = NULL; struct ifaddrs *temp_addr = NULL; int success = 0; // retrieve the current interfaces - returns 0 on success success = getifaddrs(&interfaces); if (success == 0) { // Loop through linked list of interfaces temp_addr = interfaces; while(temp_addr != NULL) { if(temp_addr->ifa_addr->sa_family == AF_INET) { // Check if interface is en0 which is the wifi connection on the iPhone if([[NSString stringWithUTF8String:temp_addr->ifa_name] isEqualToString:@"en0"]) { // Get NSString from C String address = [NSString stringWithUTF8String:inet_ntoa(((struct sockaddr_in *)temp_addr->ifa_addr)->sin_addr)]; } } temp_addr = temp_addr->ifa_next; } } // Free memory freeifaddrs(interfaces); return address; } ``` but the problem is that he get me this ip 10.0.0.1 How to get the external ip?
