iOS Detect 3G or WiFi

Question

I am not sure if this is possible, but I have this scenario.

I have a website displayed in my UIWebView which has the link set in a UISegmentedController. They website can detect if you are on wifi or on the 3g network.

Now the segmented controller points to 2 different pages: 1 - An iPhone friendly login screen 2 - The home page, once you are logged in.

Now here is the question:

Can I program my application to detect whether it is to WIFI or 3G (I know you can do this), but then based on the answer go to segment 1 or 2

Kind of like this:

if (iPhone device is on 3g) {     Go to Segment 1; } else {     Go to Segment 0; } 

Answer 1

Using the code that Apple has provided here

Reachability *reachability = [Reachability reachabilityForInternetConnection]; [reachability startNotifier];  NetworkStatus status = [reachability currentReachabilityStatus];  if(status == NotReachable)  {     //No internet } else if (status == ReachableViaWiFi) {     //WiFi } else if (status == ReachableViaWWAN)  {     //3G }
