Is there an easy way to store a reference to an arbitrary instance variable in an array?
<p>I want to store instance variable references of aribrary objects in an array, so that I can iterate over the array and set these instance variables.</p>

<p>Would I have to provide their memory addresses to the array? like </p>

<pre><code>[arr addObject:&amp;anIvar];
</code></pre>

<p>?</p>
