title: UISlider not animating in iOS7
body: <p>When I switched from iOS 6 to iOS 7 design, I noticed that using the method <code>setValue:animated:</code> no longer animates the sliding process. Has anyone else came across this problem and found a solution?</p>
  
  <p>I'll just add some code to show I've done nothing complicated:</p>
  
  <pre><code>//Variable declaration
  IBOutlet UISlider *s; //Connected in the .xib
  
  //Button pressed
  - (IBAction)buttonPressed:(id)sender
  {
      [s setValue:1 animated:YES];
  }
  </code></pre>
  
  <p>And it jumps straight to 1 after I press the button.</p>
