title: UIProgressView setProgress won't stop animating
body: <p>I seem to have the opposite problem to most people. I'm calling setProgress on my UIProgressView (which is added to my cell view). I'm calling it with NO animation but the change seems to be animated and I can't seem to switch it off.</p>
  
  <p>What I see is the bar 'slides' from the current level to the requested level instead of jumping straight there. I assume that this is what is meant by an animation?</p>
  
  <p>I'm using xcode 5.0 and simulating for the iPhone iOS7.</p>
  
  <pre><code>self.progressPlay = [[UIProgressView alloc] initWithProgressViewStyle:UIProgressViewStyleBar];
  [self.progressPlay setFrame:CGRectMake(56.0, 34.0, 225.0, 11.0)];
  [self.progressPlay setProgress:0.0 animated:NO];
  [self.progressPlay setProgressTintColor:[UIColor colorWithRed:0.431 green:0.753 blue:0.949 alpha:1.0]];
  </code></pre>
  
  <p>...and later</p>
  
  <pre><code>[self.progressPlay setProgress:progress / duration animated:NO];
  </code></pre>
