title: setHidden not working for UIPickerView
body: <p>I'm trying to show/hide a <code>UIPickerView</code> when a button is clicked, the method below is being called because the mapView hides no problem and the <code>NSLog</code> is output for both the if and else decisions, so I'm really at a loss here and very frustrated.....</p>
  
  <pre><code>- (IBAction)chooseSpot:(id)sender {
  if([spotPicker isHidden]) {
      NSLog(@"Hidden true");
      [mapView setHidden:YES];
      [spotPicker setHidden:NO];
  }
  else {
      NSLog(@"Hidden false");
      [spotPicker setHidden:YES];
      [mapView setHidden:NO];
  }
  </code></pre>
  
  <p>I'm very sure I created an <code>IBOutlet</code> and named it spotPicker, I've done it twice now....anything else I could be missing?  I'm still pretty new it could be something really stupid.....</p>
