title: Issue with UIView loaded from nib file
body: <p>I am developing an application with multiple views. I have a template for an image gallery which I have created in a xlib file. This view will be loaded as a single page in a scroll view. I am able to get the view loaded multiple time from xlib with the following:</p>
  
  <pre><code>- (void)registerForKeyboardNotifications
  {
      [[NSNotificationCenter defaultCenter] addObserver:self
                                               selector:@selector(keyboardWasShown:)
                                                   name:UIKeyboardDidShowNotification object:nil];
  
      [[NSNotificationCenter defaultCenter] addObserver:self
                                               selector:@selector(keyboardWillBeHidden:)
                                                   name:UIKeyboardWillHideNotification object:nil];
  
  }
  - (id)initWithFrame:(CGRect)frame
  {
      self = [[[NSBundle mainBundle] loadNibNamed:@"GSEstimateView" owner:self options:NULL] lastObject];
      self.commentText.delegate = self;
      self.scrollView.delegate = self;
      self.commentText.delegate =self;
      [self registerForKeyboardNotifications];
      return self;
  }
  </code></pre>
  
  <p>The first issue I am facing is, when the key board is shown the keyboardWasShown: method is getting called for as many UIViews I have created. If I try to load the keyboard from the second UIView, I get an exception for invalid selector being called. Is the UIView loaded from a nib or xlib Singleton? How can I have my UIView instance notified if I load it from nib file?</p>
