iPhone SDK: what's the difference between #import and @class?
<p>We can import class declaration with #import:</p>

<pre><code>#import "SomeClass.h"
</code></pre>

<p>or declare with @class:</p>

<pre><code>@class SomeClass;
</code></pre>

<p>What's the difference and when we should use each of them?</p>
