title: How to show the menu of UIButton().menu only when long pressed in iOS?
body: <p>By setting UIButton().menu, a menu can be shown when tapped.</p>
  <p>And a menu is shown when long pressed, too.</p>
  <p>I want to execute some another action (for example, change text) when tapped, and show a menu when long pressed.</p>
  <p>How to show a menu only when long pressed, like Safari's <code>show tabs button</code> on the right bottom of the screen?</p>
  <p>In Safari, tabs are shown when <code>show tabs button</code> is tapped, and a menu is shown when <code>show tabs button</code> is long pressed.</p>
