iPhone - a question about drawRect
<p>Suppose that instead a UIView I subclass a UIImageView and assign a background image to it, like in </p>

<pre><code>UIImageView *myImageView = [[UIImageView alloc] initWithImage: //... bla bla
</code></pre>

<p>and then I implement a drawRect method and use it to draw stuff on the image.</p>

<p>My question is:</p>

<ol>
<li>will the stuff being drawn on the
image itself or in a kind of "layer"
totally independent?</li>
<li>if the later is true, how do I
access this "layer"?</li>
</ol>

<p>thanks</p>
