title: UISlider, thumb do not move
body: <p>I have <code>slider</code> in my table's cell, here is my slider initialization code:</p>
  
  <pre><code>UISlider* slider = [[UISlider alloc] init];
  slider.continuous = NO;
  
  slider.maximumValue = 2;
  slider.minimumValue = 0.5f;
  slider.value = 0.5f;
  
  ...
  //put slider into cell
  </code></pre>
  
  <p>And I can not move this slider's thumb. Why? Please, tell me what I do wrong?</p>
  
  <p><strong>UPDATE</strong>: if set slider's initial value to 0.500001f - it works!</p>
