Question

So I make alert view detects if there in a active internet connection.

This is the Code:

- (void)viewDidLoad
{
    [super viewDidLoad];

    [[NSNotificationCenter defaultCenter] addObserver:self
    selector:@selector(reachabilityChanged:)
    name:kReachabilityChangedNotification
    object:nil];
    Reachability * reach = [Reachability reachabilityWithHostname:@"www.google.com"];
    reach.reachableBlock = ^(Reachability * reachability)
    { 
     dispatch_async(dispatch_get_main_queue(), ^{
     blockLabel.text = @"";  
     });
    };
    reach.unreachableBlock = ^(Reachability * reachability)
    {
     dispatch_async(dispatch_get_main_queue(), ^{
     blockLabel.text = @"You are not connected to the Internet";
     UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Please connect to Internet"
     message:nil
     delegate:self
     cancelButtonTitle:nil
     otherButtonTitles:nil];
     UIActivityIndicatorView *progress= [[UIActivityIndicatorView alloc] initWithFrame:CGRectMake(125, 50, 30, 30)];
     progress.activityIndicatorViewStyle = UIActivityIndicatorViewStyleWhiteLarge;
            [alert addSubview:progress];
            [progress startAnimating];
            [alert show]; 
        });
    };
    [reach startNotifier];
    // Do any additional setup after loading the view, typically from a nib.
}

So my application detects if there is a internet connection. But the issue is that if I turn on internet on the iPhone and open the application it still saying there is not internet connection. What should I do…

Well i fix the issue by using notifications.. Code for Reference

-(void)reachabilityChanged:(NSNotification*)note
{
    Reachability * reach = [note object];

    if([reach isReachable])
    {
        notificationLabel.text = @"Notification Says Reachable";
        NSLog(@"Internet is Up");
    }
    else
    {
        notificationLabel.text = @"Notification Says Unreachable";
        NSLog(@"Internet is Down");
    }
}
