title: UIViewController is not key value coding-compliant for the key XXXXX. No wrong connections in IB
body: <p>I get runtime error when displaying EditViewController from my main view controller:</p>
  
  <pre><code>'[&lt;EditViewController 0x7fbef90&gt; setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key saveChanges.'
  </code></pre>
  
  <p>I've done all the different Google/Stack Overflow searches I can think of and all of my results refer to either a Tab Bar or a bad connection in Interface Builder. My project has no tab bar and I removed every connection (except that from the File's Owner, EditViewController, to the view) from every object in my nib. EditViewController does, in fact have a method named <code>-(IBAction)saveChanges</code>.</p>
  
  <p>It's driving me crazy, and I can't figure out what on earth I'm supposed to do. Thanks in advance.</p>
