title: NSNotifcation for UIMenuControllerWillShowMenuNotification
body: <p>I am trying to listen for UIMenuController Notification in iphone sdk <strong>3.0</strong> .</p>
  
  <p>But it seems that my notification can never get called. Here is my code:</p>
  
  <pre><code>    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(menuControllerWillShow:) name:UIMenuControllerWillShowMenuNotification object:nil];
  </code></pre>
  
  <p>and my method</p>
  
  <pre><code>- (void)menuControllerWillShow:(NSNotification *)notification {
     NSLog (@"Call here");
  }
  </code></pre>
  
  <p>But it never prints out "Call here", breakpoint never gets stop as well. Does anyone know how to solve this problem.</p>
  
  <p>I know the approach of setMenuItems for iphone sdk <strong>4.0</strong> but I am working for sdk 3.0.</p>
  
  <p>My original problem is that I am trying to catch the UIMenuController event to show a toolbar of buttons like: "Do A", "Do B" for the text. If anybody knows any solution for this, I also appreciate</p>
