iOS: switch to second ViewController

I am working on a script that uses Reachability to check for an Internet connection. If there is No Internet I want it to load a second ViewController. This is what I have so far:

-(BOOL) hasInternet {
    Reachability *reach = [Reachability reachabilityWithHostName:@"http://www.google.com"];
    NetworkStatus internetStatus = [reach currentReachabilityStatus];
    if( internetStatus == NotReachable){
        SecondViewController *second = [[SecondViewController alloc] initWithNibName:nil bundle:nil];
        [self presentViewController:second animated:YES completion:nil];
    }else{

    }
    return YES;
}

The error I am getting is:

Attempt to present SecondViewController: 0x7ff780628d10 on ViewController: 0x7ff780719830 whose view is not in the window hierarchy!

Can anyone see where I am going wrong.

Many thanks in advance for your help and time.

You are attempting to present another viewController while first ViewController has yet not loaded.

Solution:

  1. Call your function inside viewDidAppear() method.
  2. Write View Controllers Nib Name that you want to load
