title: UIScrollView not responding to touches
body: <p>I have an UIScrollView in which I display tweets. The scrollView is contained in a stack of views, the last of which has 4 gesture recognizers.</p>
  
  <p>The scrollView is populated as follows:</p>
  
  <pre><code>- (void) createTimeLine:(NSArray*)timeline
  {
      CGRect rect = CGRectMake(0, 0, 463, 150);
      NSInteger i = 0;
      NSLog(@"timeline objects: %d", timeline.count);
      self.scrollView.contentSize = CGSizeMake(463, timeline.count * 150);
      for (NSDictionary *d in timeline) {
          SingleTwitViewController *c = [[SingleTwitViewController alloc] initWithAsingleTwit:d];
          rect.origin.y = i * 150;
          c.view.frame = rect;
          [scrollView addSubview:c.view];
          [scrollView bringSubviewToFront:c.view];
          i += 1;
      }
  }
  </code></pre>
  
  <p>There are 20 objects in the timeline, and the first 4 are visible. However, the scrollView does not scroll and the touches are handeled by the gesture recognisers.</p>
  
  <p>The <code>scrollEnabled</code> property is set to YES, but for some reason this does not seem to work. </p>
  
  <p>The contentSize is set to 463 * 3000 which is much less than the scrollView it self, but still it won't scroll.</p>
  
  <p>Any ideas?</p>
