title: UIView animation trying to change the frame size doesn't work in iOS 8 but in iOS 7
body: <p>I wanted to resize an UIView, my code works perfect in iOS 7.1 but when I run it in iOS 8 it didn't work properly (I will explain below).</p>
  
  <p>I have my UIView int the storyboard with values (0,67,511,320), I want to resize to full screen on iPad, so I added the following code:</p>
  
  <pre><code>        [UIView animateWithDuration:0.5 animations:^{
  
              CGRect frame = containerView.frame;
              frame.origin.x = 0;
              frame.origin.y = 67;
              frame.size.height = 643;
              frame.size.width = 1024;
              containerView.frame = frame;
              ...
  
          }completion:^(BOOL finished) {
              ...
          }];
  </code></pre>
  
  <p>I wanted something like:</p>

  <p>But it starts the animation like (0,67,0,0) to (0,67,511,320)</p>
