wifi is connected and internet is not available iOS

Question

My question is same as this question, but don't get a proper answer.

If I am connected to wifi, but internet is not available/gone it should be notify. Alslo tested using Apple Reachability demo but still its not working.

Steps to reproduce:

1) connect iPhone using tethering on another device.

2) run the apple rechability demo.

3) turn off the cellular data on another device on wich iPhone is connected.

Did you try to connect to an host or an IP Address with Reachability? — Larme, Dec 13 '16 at 15:10
I think it's a problem that's a device has tethering on and cellular data off... Anyway a wifi connection can be for internal private network that doesn't connected to the internet... I don't understand what you are asking... — Yitzchak, Dec 13 '16 at 15:35

You can simply call the below code and then call NSURLConnection delegate methods. This way even if wifi is connected and internet not available it can be detected.

NSMutableURLRequest *headerRequest = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"http://www.google.com"] cachePolicy:NSURLRequestReloadIgnoringLocalAndRemoteCacheData timeoutInterval:10.0];
    headerRequest.HTTPMethod = @"HEAD";
    self.headerConnection = [[NSURLConnection alloc] initWithRequest:headerRequest delegate:self];

That's fine, but how can I notified when internet is gone ? – Dinesh Kachhot Dec 14 '16 at 08:43
You don't. In iOS, the proper thing to do is attempt your network operation and pay attention to errors. – Avi Dec 14 '16 at 15:33
