Define a method that can be interpreted by the return value, or directly in the method.

Here's one of the methods

-(void) Networkstatechange

{

//1. Detection WiFi Status

reachability *wifi = [reachability Reachabilityforlocalwifi];

//2. detect if the phone can be on the network (wifi\3g\2.5g)

reachability *conn = [reachability reachabilityforinternetconnection];

//3. Determine network status

if ([WiFi currentreachabilitystatus]! = Notreachable | | [Conn Currentreachabilitystatus]! = notreachable) {// have wifi

}else { // No network

}

}
