title: UIView animation options have no effect
body: <p>I am trying to apply an easing animation to a UILabel translation, but if I do this:</p>
  
  <pre><code>[UIView animateWithDuration:0.5f delay:0 options:UIViewAnimationOptionCurveEaseOut animations:^{
     CGRect frame = _section.frame;
     frame.origin.y = -100;
     _section.frame = frame;
  } completion:^(BOOL finished){}];
  </code></pre>
  
  <p>I see a linear animation, the same result as when I pass <code>0</code> as the <code>options</code>.</p>
  
  <p>How can I get the animation options working?</p>
