title: Could not connect the action cancelAction: to target of class NSViewController
body: <p>I'm new to mac development. I developed an application using the <code>NSTabView</code> in which al worked fine for me.</p>
  
  <p>But later I wanted to change the UI so I used <code>NSSplitView</code> in this I'm able to display the xib, but the button action are not happening, and I'm getting an error:</p>
  
  <blockquote>
    <p><strong>Could not connect the action cancelAction: to target of class NSViewController</strong>".</p>
  </blockquote>
  
  <pre><code>- (IBAction)cancelAction:(id)sender
  {
      [self enableNewProductAction];
  }
  </code></pre>
  
  <p>How can I fix this problem?</p>
