title: UITapGestureRecognizer not working in UIImageView
body: <p>I had the following code:</p>
  
  <pre><code>UITapGestureRecognizer *showStoryTapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(showNewsStory:)];
  [showStoryTapRecognizer setDelegate:self];
  [self.storyImageView_ addGestureRecognizer:showStoryTapRecognizer];
  [showStoryTapRecognizer release];
  </code></pre>
  
  <p>This however doesn't trigger the showNewsStory, why is this? I have enabled userInteraction in the image view.</p>
