copy array into another array
<p>I have an <code>NSMutableArray</code> something like this</p>

<pre><code>array =[[a1,b1,c1],[a2,b2,c2],[a3,b3,c3].......]
</code></pre>

<p>and I access this array for particular object like</p>

<pre><code>array.a =[a1,a2,a3]
array.b =[b1,b2,b3]
</code></pre>

<p>what I am trying to do is to copy all elements which are in <code>array.b</code> into an another array say <code>arrayABC</code>.</p>

<p>something like this <code>arrayABC = [a1,a2,a3....]</code></p>

<p>HOw can i do that..

<p>regards</p>
