title: Open UIDatePicker programmatically in iOS 14
body: <p>I have this normal <code>UIDatePicker</code> (sorry that it's not in English, please ignore that):</p>
  <p><img src="https://i.stack.imgur.com/M0os7.png" alt="my date picker" /></p>
  <p>But the problem is that it only appears when I'm pressing the Date Picker:</p>
  <p><img src="https://i.stack.imgur.com/tTHfY.png" alt="image" /></p>
  <p>And I wanted to know how to show the Date Picker like in the first image (that it's covering all the screen with the blur effect) <strong>only with code</strong>, so the user won't need to press the Date Picker to show the date selector. Thanks.</p>
