title: Length of an `int` array in Objective C
body: <p>I am passing an Integer array to a function.
  Next I want to traverse through the array.
  In C and C++ this worked by simply using <code>arrayname.length</code> which gave the number of elements in array.  What is the way to find that in Objective-C?</p>
  <p><code>[NSArrayObject length]</code> works for <code>NSArray</code> type but I want it for <code>int[]</code>.  Not even <code>[XYZ count]</code> works (an already suggested answer) so I'm looking for another way here.</p>
