How to check whether internet is active (checking both network availability & webpage accessibility) in iOS?

I am currently working in an iOS project where I need to check whether my phone is connected to the internet (mobile data/wifi) or not . I'm using reachability class which only check network connection availability but suppose a scenario where there is no balance in my phone . In that case I wouldn't able to access internet but still reachability shows me that internet is reachable via mobile network as data connection is on although I can't access the page .

How can I resolve the issue ? Anyone plz. give me some clue as my project deadline is approaching fast.

you can check using connection:didReceiveResponse:

        NSString *urlString=@"yourUrl";
        NSURL *url=[NSURL URLWithString:urlString];
        NSURLRequest *request=[NSURLRequest requestWithURL:url];
        NSURLConnection *connection=[NSURLConnection connectionWithRequest:request delegate:self];
        [connection start];

        -(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
        [connection cancel];
        NSHTTPURLResponse* httpResponse = (NSHTTPURLResponse*)response;
        int code = (int)[httpResponse statusCode];
        if (code == 200) {
            NSLog(@"File exists");
        else if(code == 404)
            NSLog(@"File not exist");
        -(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
        NSLog(@"File not exist");
