  <p>I have a string with double double quotes "" that I need to replace with single double quotes ".</p>
  
  <p>I've tried the following but I still end up with double double quotes</p>
  
  <pre><code>NSString *str = @"This is a \"\"99\"\" string";
  [str stringByReplacingOccurrencesOfString: @"\"\"" withString: @"\""];
  </code></pre>
  
  <p>Initially the string is: This is a ""99"" string</p>
  
  <p>After the stringByReplacingOccurrencesOfString: This is a ""99"" string.</p>
  
  <p>What am I doing wrong?</p>
