title: UIBarButtonItem: target-action not working?
body: <p>I've got a custom view inside of a <code>UIBarButtonItem</code>, set by calling <code>-initWithCustomView</code>.
  My bar button item renders fine, but when I tap it, it doesn't invoke the action on my target object.</p>
  
  <p>Here's my code:</p>
  
  <pre><code>UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"someImage.png"]];
  UIBarButtonItem *bbItem = [[UIBarButtonItem alloc] initWithCustomView:imageView];
  self.navigationItem.leftBarButtonItem = bbItem;
  [imageView release];
  [bbItem setTarget:self];
  [bbItem setAction:@selector(deselectAll)];
  </code></pre>
