title: UIProgressView custom track and progress images in iOS 7.1
body: <p>iOS 7.1 seems to have broken the custom image properties in <code>UIProgressView</code>.  Code that used to successfully customize progress views now yields the default appearance.</p>
  
  <p>I set up a sample project that does this in <code>viewDidLoad</code>:</p>
  
  <pre><code>self.progressView.frame = CGRectMake(self.progressView.frame.origin.x, self.progressView.frame.origin.y, self.progressView.frame.size.width, 9);
  UIImage *img = [UIImage imageNamed:@"progress_bar_fill.png"];
  img = [img resizableImageWithCapInsets:UIEdgeInsetsMake(0, 4, 0, 4)];
  self.progressView.progressImage = img;
  
  img = [UIImage imageNamed:@"progress_bar_empty.png"];
  img = [img resizableImageWithCapInsets:UIEdgeInsetsMake(0, 4, 0, 4)];
  self.progressView.trackImage = img;
  </code></pre>
  
  <p>I still get the default appearance.  I've stepped through and verified that <code>img</code> is non-nil as expected.  What's going on?</p>
  
  <p><b>UPDATE:</b> There is an <a href="http://openradar.io/16113307">OpenRadar</a> for this, and I've also filed a radar of my own complete with a sample project.</p>
  
  <p><b>UPDATE 2:</b> As noted by Axy below, you have to add this to get the JEProgressView to work correctly:</p>
  
  <pre><code>_progressBar.tintColor = [UIColor clearColor];
  </code></pre>
