title: How to set linear gradient to background of LaunchScreen.xib in iOS
body: <p>Is there any way to set linear gradient to background of LaunchScreen.xib in iOS? Something like <code>background="linear-gradient(#000000, #123456)"</code>?</p>
  
  <pre><code>&lt;view contentMode="scaleToFill" background="..."&gt;
      &lt;rect key="frame" width="753" height="867"/&gt;
  &lt;/view&gt;
  </code></pre>
