iPhone - having a superclass calling methods on subclasses...(?)
<p>I have several subclasses that derive from one superclass. Lets call this superclass "classA".</p>

<p>All subclasses of classA have a method called <strong>doStuff:(id)sender</strong> and every of these methods in each class does things relative to that class.</p>

<p>The problem is that I have to call doStuff from classA. </p>

<p>How do I do that?</p>

<p>Should I declare <strong>doStuff:(id)sender</strong> on classA as an empty method, like</p>

<pre><code>- (void) doStuff:(id)sender {
}
</code></pre>

<p>just to have it compile correctly and then overwrite that on the subclass declaring it again? Is this the correct way to do that?</p>

<p>thanks.</p>
