title: How do I reset NSSplitView views
body: <p>This is a little hard to explain, but I will try my best.</p>
  
  <p>This is how I setup my <code>NSSplitView</code> inside my mainWindow.</p>
  
  <pre><code>[self.splitView.subviews[0] addSubview:view0];
  [self.splitView.subviews[1] addSubview:view1];
  [self.splitView.subviews[2] addSubview:view2];
  </code></pre>
  
  <p>However, if I close the mainWindow and reopen it the views do not "reset" so to speak. It still has previous information for a little while until my app retrieves new information. Is there an elegant way to reset NSSplitView views? Thank you for any tips you might have.</p>
  
  <p>Edit: I tried releasing my MainWindow, but if I do that I can't reopen the the window.</p>
