title: Objective-C/Xcode - Switch between view controllers programatically?
body: <p>How do you switch between view controllers programatically in an effective manner? 
  I am currently utilising:</p>
  
  <pre><code>ViewController *viewController = [[ViewController alloc] init];
      [self presentViewController:viewController animated:YES completion:nil];
  </code></pre>
  
  <p>However this does not display the items that I've inserted using the interface builder. Only the items I've inserted programatically.</p>
  
  <p>I wish to do this, as I want to display a home button on each page.</p>
