title: Do we need to deallocate CFArray?
body: <p>I have a <code>CFMutableArray</code> that I created using <code>CFArrayCreateMutable</code>.
  I just need to know whether I need to deallocate this array by myself, or is it already taken care by the ARC? If I need to deallocate this, how can I, since I didn't find any function like <code>CFArrayRelease</code>?</p>
