UIButton delayed state change
<p>I have a <code>UIButton</code> subview inside of a <code>UITableViewCell</code>.</p>

<p>When this button is touched, the user must hold the button for about a half second for the button's image to change to the <code>UIControlStateHighlighted</code> image.</p>

<p>This means that if the user just taps the button as is usually the case, the highlighted state is never shown.</p>

<p>Why does this occur and how can I fix it?</p>
