title: ViewController won't update after load
body: <p>I got two viewControllers using a navigation bar. The first viewController displays some data I change on the second viewController.</p>
  
  <p>So if I load the second viewController, a back button appears in the NavBar and I can change my values (and they <strong>are</strong> stored, I used the debugger). My problem is, after hitting the backButton to come to my firstView Controller, it does not call it's <code>viewDidLoad</code> method. It's clear, that there are no updated values at all, when this function is not called.</p>
  
  <p>At the first start, the <code>viewDidLoad</code> method is called and does what I want it to do. After going back and forth between the viewControllers the method is not called again.</p>
  
  <p>Any solutions?</p>
  
  <p>Thanks!</p>
  
  <p>EDIT:</p>
  
  <p><strong>SOLVED</strong></p>
  
  <p>I did not want to delete my question, maybe someone needs this too:</p>
  
  <p>This method is called every time the view appears, it is probably not defined by default:</p>
  
  <pre><code>-(void)viewDidAppear:(BOOL)animated
  {
  NSLog(@"View appeared.");
  }
  </code></pre>
