title: UIProgressView doesn't change height after changing appearance, but change after rotating device
body: <p>I've set track image and progress image using <code>[UIProgressView appearance]</code>. Images set, but height of <code>UIProgressView</code> didn't change. It changes only after rotating device to lanscape. Where could be problem? Setting <code>UIProgressView's</code> frame doesn't help.</p>
  
  <pre><code>//image size 13x13 px.
  [[UIProgressView appearance] setProgressImage:[[UIImage imageNamed:@"UploadingProgress_1.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(6, 6, 6, 6)]];
  [[UIProgressView appearance] setTrackImage:[[UIImage imageNamed:@"Uploading_1.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(6, 6, 6, 6)]];
  </code></pre>
  
  <p><strong>SOLVED</strong> with <code>[[UIProgressView appearance] setFrame:]</code> method.</p>
