title: if NSString does not equal function?
body: <p>I have searched all over the place for this, including apple's docs on NSString (maybe I didn't see?) but I am trying to find a method in xCode for checking wether a NSString does not equal to something. Much like</p>
  
  <pre><code>if (myNSSting = @"text" {...
  </code></pre>
  
  <p>except specifically I want to check if it does not equal to 'text'.</p>
