title: How can the appearance of Button Shapes enabled through the Accessibility settings be influenced in iOS 7.1?

  <p>The release of iOS 7.1 brings the availability of <strong>Button Shapes</strong> under the <strong>Accessibility settings.</strong> I've noticed that their appearance can be inconsistent within my app. Mostly, I'm getting a black background after having implemented a <code>UIBarButtonItem</code> using Interface Builder. Touching the button but not fully tapping it results in the image turning gray. How can the appearance of the button shapes be influenced so that they will not look so out of place as having a solid black background and more like the gray background as shown in the attached image? In this case I do not want to use a custom control.</p>
