POAlternatives to NSHost in iPhone app
text
Body
copied!<p>I'm currently using this code</p> <pre><code> NSHost *host = [NSHost hostWithAddress:hostname]; if (host == nil) { host = [NSHost hostWithName:hostname]; if (host == nil) { [self setMessage:@"Invalid IP address or hostname:"]; return; } } </code></pre> <p>to retrive my IP Address for a networking app I'm working on, however I'm aware that NSHost is a private API that will be rejected. Can anyone help me with working this code to produce the same results without using NSHost? I'm not really sure where to start.</p> <p>EDIT:</p> <p>Following suggestions that seem damn near perfect below I've added this code into my app in the place of the code above</p> <pre><code> Boolean result; CFHostRef hostRef; CFArrayRef addresses; NSString *hostname = @"www.apple.com"; hostRef = CFHostCreateWithName(kCFAllocatorDefault, (CFStringRef)hostname); if (hostRef) { result = CFHostStartInfoResolution(hostRef, kCFHostAddresses, NULL); // pass an error instead of NULL here to find out why it failed if (result == TRUE) { addresses = CFHostGetAddressing(hostRef, &result); } } if (result == TRUE) { NSLog(@"Resolved"); } else { NSLog(@"Not resolved"); } </code></pre> <p>I've removed the 4th line (as I have this information from elsewhere already) but I get errors being based around CFHostRef being undeclared. How would I resolve that? It seems to be my only big hurdle, as other errors are only based upon the lack of being able to see hostRef after that. EDIT: Scratch that I also get kCFHostAddresses undeclared.</p>
