Is there a method to clear UILabel and UIImageView?
<p>Is there another way to clear a <code>UILabel text</code> and a <code>UIImageView image</code> without doing something like this?</p>

<pre><code>label.text = @"";
image setImage:[UIImage imageNamed:@""];
</code></pre>

<p>Are there methods to execute these actions?  </p>
