title: case insensitivity in NSArray containsObject:
body: <p>I'm working on an app that checks an array to see if it contains a certain string. However, it doesn't seem to be working right, because I think it may be looking at the case of the string. 
  In this line of code, how would I make sure that containsObject: is being case insensitive?</p>
  
  <pre><code>if ([myArray containsObject:term]) {...}
  </code></pre>
  
  <p>Please ask if you need clarification, and thanks for your help.</p>
  
  <p>(Also, I've found this question: <a href="https://stackoverflow.com/questions/2582306/case-insensitive-comparison-nsstring">Case insensitive comparison NSString</a>. I don't know if this is what I need, and if it is, how would I use it)</p>
