title: adding content to UIScrollView
body: <p>I am trying to put a web view below an image in a scrollview. This code leads to a blank screen. I'm sure it's extremely simple (I'm a beginner), but could someone point me to my mistake?</p>
  
  <pre><code>- (void)viewDidLoad
  {
      [super viewDidLoad];
      self.title = [self.detailItem title];
      //self.webView = [[UIWebView alloc] init];
      //self.imageView = [[UIImageView alloc] init];
      UIImage* image = [UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:[self.detailItem imageURL]]]];
  
      self.imageView.image = image;
      [self.webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:[self.detailItem url]]]];
  
      [self.scrollView addSubview:self.imageView];
      [self.scrollView addSubview:self.webView];
      self.imageView.frame = CGRectMake(0, 770, 320, 230);
      [self.webView setFrame:CGRectMake(0, 0, 320, 770)];
      CGFloat scrollViewHeight = 1000.0f;
      /*
      for (UIView* view in scrollView.subviews)
      {
          NSLog(@"%f",view.frame.size.height);
          scrollViewHeight += view.frame.size.height;
  
      }
      */
      [scrollView setContentSize:(CGSizeMake(320, scrollViewHeight))];
      NSLog(@"%f", self.imageView.frame.size.height);
      NSLog(@"%f", self.webView.frame.size.height);
  
      [self configureView];
  }
