title: Antialiasing edges of UIView after transformation using CALayer's transform
body: <p>I have a <code>UIView</code> object that rotates using <code>CALayer</code>'s transform:</p>
  
  <pre><code>// Create uiview object.
  UIImageView *block = [[UIImageView alloc] initWithFrame....]
  
  // Apply rotation.
  CATransform3D basicTrans = CATransform3DIdentity;
  basicTrans.m34 = 1.0/-distance;
  blockImage.layer.transform = CATransform3DRotate(basicTrans, rangle, 1.0f, 0.0f, 0.0f);
  </code></pre>
  
  <p>After rotating the edges of the object are not antialiasing. I need to antialias them.
  Help me, please. How can it be done?</p>
