title: UISegmentedControl does not respond on UIControlEventValueChanged in UIToolbar
body: <p>I created a control with some items</p>
  
  <pre><code>NSArray *items = [NSArray arrayWithObjects: @"First", @"Second", @"Third",  nil];
  UISegmentedControl *segmentedControl = [[UISegmentedControl alloc] initWithItems:items];
  </code></pre>
  
  <p>I added target to the control</p>
  
  <pre><code>[segmentedControl addTarget:self
                       action:@selector(controlTapped:)
             forControlEvents:UIControlEventValueChanged];
  </code></pre>
  
  <p>Than i added my segmented control to the toolbar</p>
  
  <pre><code>[toolbar setItems:[NSArray arrayWithObject:
                            [[[UIBarButtonItem alloc]initWithCustomView:segmentedControl]autorelease]]];
  </code></pre>
  
  <p>As a result segmentedControl doesn't respond on user tap.</p>
  
  <p>Here is the empty empty method</p>
  
  <pre><code>-(void) controlTapped:(id)sender {
  </code></pre>
  
  <p>}</p>
