title: Animation and UILabel change text
body: <p>I have an UIImageView and an UILabel in a view of my storyboard. I created 2 corresponding IBOutlet and an NSTimer in the controller.</p>
  
  <p>Each 0.01 seconds, the timer call the following method which moves the image:</p>
  
  <pre><code>-(void) update{
  
      CGRect rect = myImageOutlet.frame;
      rect.origin.x += 1;
      myImageOutlet.frame = rect;
  }
  </code></pre>
  
  <p>It works well. Now I would also like to change the text of the label in this method in order to display the current elapsed time (to do so I initialize an NSDate in the viewDidLoad and I use on it the method timeIntervalSinceNow)</p>
  
  <p>Now the text of the label changes correctly but the image stays at it's original place.</p>
  
  <p>I found a workaround by adding <strong>programmatically</strong> to my controller a subview and putting the label in this subview.</p>
  
  <p>What is strange is that I tried to do the same by adding an UIView and an UILabel through the object library in the storyboard (and not programmatically), and it does not work.</p>
  
  <p>Do you have any idea why ?
  (and if you also know why the image is not moving if I change the label text I am interested)</p>
