Alternative method to check network connectivity using Reachability

Import Reachability file and create an object of Reachability

[self checkReachability];

-(void)checkReachability {

    

    [[NSNotificationCenter defaultCenter] addObserver:self

                selector:@selector(reachabilityChanged:)

                name:kReachabilityChangedNotification object:nil];

    

    reachability = [Reachability reachabilityWithHostName:@"www.google.com"];

    [reachability startNotifier];

}

- (void)reachabilityChanged:(NSNotification* )notification {

    

    Reachability* curReach = [notification object];

    if ([curReach currentReachabilityStatus] == NotReachable) {

        NSLog(@"Server not reachable....");

        [self hideOverlay];       

    }

    else {

        NSLog(@"Server reachable ....");

        

    }

}
