I found this sample code to get all local IP addresses, but I don't find an easy solution to get the public IP.

It's as simple as this:

NSString *publicIP = [NSString stringWithContentsOfURL:[NSURL URLWithString:@"https://icanhazip.com/"] encoding:NSUTF8StringEncoding error:nil];
publicIP = [publicIP stringByTrimmingCharactersInSet:[NSCharacterSet newlineCharacterSet]]; // IP comes with a newline for some reason
