iOS DDMathParser get solving steps of math expression
<p>I am building a some kind of calculator for iOS using DDMathParser. I would like to know how to separate an expression (NSString) like <code>3+3*4 (After parsing add(3,multiply(3,4)))</code> into its individual steps:<code>multiply(3,4) add(3,12)</code>. I would prefer that I get these in an NSArray or other relatively useful list object. </p>

<ul>
<li><code>Example: add(3,multiply(3,4))</code></li>
<li><code>[1] multiply(3,4)</code> </li>
<li><code>[2] add(3,12)</code> </li>
<li><code>[3] 15</code></li>
</ul>
