<p>Depending on the transition in use, different properties of a <code>UIViewController</code> are set to make sure the transition animation is used.</p>
<div class="aside aside-note">
    <p class="aside-title">Note</p>
    <p>To not override the previously set <code>Animation</code>, use <code>nil</code> when initializing a transition.</p>

<p>Make sure to hold a strong reference to the <code>Animation</code> object, as it is only held by a weak reference.</p>
