zoomScale for OS 2.0
<p>Is there any alternative or work around so that I can use zoomScale in Iphone OS 2.0. It seems the property is only available in Iphone OS 3.0 or later?</p>

<p>I have two subviews in my UIScrollView and if the first subview reach a specified scale then it will change to the other subview and save the current scale to zoomScale so that the new subview will apply to the previous scale. Like for example in, scrollViewDidEndZooming,</p>

<pre><code>scrollView.zoomScale = scale;
</code></pre>

<p>When I run my app in Iphone OS 2.0, it gives me error saying invalid zoomScale invalid selector.</p>

<p>How can I work around this?</p>

<p>Thanks.</p>
