Simplest of ways:

reach = [Reachability reachabilityWithHostName:@"www.google.com"];
 reach.reachableBlock = ^(Reachability *reach){
    NSLog(@"Reachable");
};

reach.unreachableBlock = ^(Reachability *reach){
    NSLog(@"Unreachable");
};
[reach startNotifier];

Everytime there is a change in network,respective blocks will be called.
