title: Xcode : Count elements in string array
body: <p>Is there any quick way I can get the number of strings within a NSString array?</p>
  
  <pre><code>NSString *s[2]={@"1", @"2"}
  </code></pre>
  
  <p>I want to retrieve the length of <strong>2</strong> from this. I there something like (s.size) 
  I know there is the -length method but that is for a string not a string array.
  I am new to Xcode please be gentle.</p>
