title: Anyway to animate UIImageView's contentMode from aspectFill to aspectFit?
body: <pre><code>[UIView animateWithDuration:30.0f delay:0.0f options:UIViewAnimationOptionCurveEaseInOut animations:^{
      v.contentMode = UIViewContentModeScaleAspectFit;
      v.frame = v.superview.bounds;
  } completion:^(BOOL finished) {
      [v removeFromSuperview];
  }];
  </code></pre>
  
  <p>I want a UIImageView to resize and change the contentMode, but the code above doesn't work. It changed the contentMode immediately at the beginning of the animation.</p>
  
  <p>Is there any way to animate it?</p>
