title: UIScrollView within ScrollView - ScrollBars not showing
body: <p><strong>BackStory</strong></p>
  
  <p>I am writing an ipad app which has images that scrolls horizontally using a UIScrollView. This works fine. Now for each image i need to have a UIScrollView which has some kind of text explaining the image. This would be a vertical scrollView. The vertical ScrollView appears but then the scrollbars dont appear. Any idea why? Code below : </p>
  
  <pre><code>CGRect scrollViewFrame = CGRectMake(760, 70, 205, 320);
  UIScrollView * contentScrollView = [[UIScrollView alloc]initWithFrame:scrollViewFrame];
  [contentView addSubview:contentScrollView];
  CGSize scrollViewContentSize = CGSizeMake(205, 100);
  [contentScrollView setContentSize:scrollViewContentSize];
  [contentScrollView setPagingEnabled:YES];
  contentScrollView.delegate = self;
  
  UILabel *titleLable = [[UILabel alloc] initWithFrame:CGRectMake(10, 10, 205, 40)];
  UILabel *subtitleLable = [[UILabel alloc] initWithFrame:CGRectMake(10, 60, 205, 50)];
  UITextView * mainContent = [[UITextView alloc]initWithFrame:CGRectMake(10, 110, 205, 230)];
  
  [titleLable setText:storyTitle];
  [subtitleLable setText:storySubTitle];
  [contentView setUserInteractionEnabled:YES];
  [mainContent setText:storyDescription];
  </code></pre>
  
  <p>Also the main scrolView is already added using Interface Builder and is working fine. Does wnyone know why this is happening? </p>
