title: Case insensitive compare strings in Objective-C
body: <p>I want to compare 2 strings. I am doing it like this:</p>
  
  <pre><code>[someString isEqualToString:otherString];
  </code></pre>
  
  <p>But I have the problem that when there are capital letters but the words are the same I don't get a YES as result.</p>
