title: Displaying percentage using NSString
body: <p>How do we display percentage character in objective-c?</p>
  
  <p>I am using this:</p>
  
  <pre><code>[NSString localizedStringWithFormat:@"%.2f %", percentageQs]
  </code></pre>
  
  <p>But for some reason, it doesn't recognize the %. thought i could escape it using this \ but i was so wrong.</p>
