title: Navigate to another ViewController programmatically using Custom Segue
body: <p>I have two view controllers in the storyboard. I did successfully navigate from the 1st one to 2nd one programmatically:</p>
  
  <pre><code>UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
  YourViewController *yourViewController = (YourViewController *)[storyboard instantiateViewControllerWithIdentifier:@"yourViewControllerID"];
  [self.navigationController pushViewController:yourViewController animated:YES];
  </code></pre>
  
  <p>I want to use my <code>custom</code> Segue to navigate to other page instead of <code>pushViewController</code> without using interface builder.</p>
  
  <p>This is my custom Segue that I could easily use with interface builder:</p>
  
  <pre><code>@interface LeftToRightSegue : UIStoryboardSegue
  </code></pre>
  
  <p>How about do it programmatically?</p>
