Here is a code snippet you can use:

[[Reachability sharedReachability] setHostName:@"example.com"];
if ([[Reachability sharedReachability] remoteHostStatus] == NotReachable) {
    UIAlertView *dialog = [[[UIAlertView alloc] init] retain];
    [dialog setTitle:@"Server unreachable"];
    [dialog setMessage:@"The server is temporarily unavailable."];
    [dialog addButtonWithTitle:@"OK"];
    [dialog show];
    [dialog release];
}

Apple's recommendation is to do something like (or use) Reachability

Have a look at the apple sample code Reachability. It should provide you with everything you need.
