title: performSegueWithIdentifier and viewDidLoad
body: <p>MainViewController: </p>
  
  <pre><code>[self performSegueWithIdentifier:@"showNextVC sender:self];
  </code></pre>
  
  <p>Segue destination controller:</p>
  
  <pre><code>- (void)viewDidLoad {
  [super viewDidLoad];
  NSLog(@"Show text!");
  [self performSegueWithIdentifier:@"showSignUp" sender:self]; }
  </code></pre>
  
  <p>Why doesn't the code from the destination controller's viewDidLoad method execute?</p>
