title: Objective C take substring of string
body: <p>I have the following string :</p>
  
  <pre><code>[["hello","goodbye"]]
  </code></pre>
  
  <p>and I try to take "hello" and "goodbye" into two separates strings. I use:</p>
  
  <pre><code>NSArray *str = [mystring componentsSeparatedbyString:@"""];
  </code></pre>
  
  <p>so I cannot use <code>@"""</code> because <code>"</code> is a reserved character.</p>
