title: UIBarButtonItem normal and pressed states switched?
body: <p>I created a toolbar with a translucent black style like so:</p>
  
  <pre><code>UIToolbar *toolbar = [UIToolbar new];
  toolbar.barStyle = UIBarStyleBlack;
  toolbar.translucent = YES;
  </code></pre>
  
  <p>I created a button item for it:</p>
  
  <pre><code>UIBarButtonItem *buttonItem = [[UIBarButtonItem alloc] initWithImage:nil
                              style:UIBarButtonItemStyleBordered
                            target:self
                              action:@selector(mySelector:)];
  </code></pre>
  
  <p>I noticed that the button when in normal state appears light grey and turns to full black only when I press on it. This seems to be the opposite of how it should function (e.g. Photo app). I'd like it do be black in normal state and lighter when pressed. What am I missing?</p>
