title: Strange behaviour when laying out subviews
body: <p>I am creating a UI that the user can page through multiple views by using a UIScrollView. I create the UIView objects in code and add them to UIScrollView. I use the code below to create the views.</p>
  
  <pre><code>CGRect frame;
  frame.origin.x = self.scrollView.frame.size.width * i;
  frame.origin.y = 0;
  frame.size = self.scrollView.frame.size;
  
  UIView *brandView = [[UIView alloc] initWithFrame:frame];
  
  UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0.0, 50.0, frame.size.width, 30)];
  label.text = [brand objectForKey:@"name"];
  label.textAlignment = UITextAlignmentCenter;
  label.backgroundColor = [UIColor redColor];
  [brandView addSubview:label];
  
  UIImageView *logoImageView = [[UIImageView alloc] init];
  logoImageView.frame = CGRectMake(20.0, 100.0, 280.0, 300.0);
  [brandView addSubview:logoImageView];
  logoImageView.file = [brand objectForKey:@"logo"];
  [logoImageView loadInBackground];
  </code></pre>
  
  <p>Although I give 50.0 for the y coordinate for the label, I can't see the label at all when I run the app. And logoImageView has 100.0 for its top but it appears just below the status bar, as if it had 0.0 for it's y coordinate.</p>
  
  <p>What is the reason for this strange behaviour, am I doing something wrong?</p>
  
  <p>Note: Auto layout for the UIScrollView is disabled on IB.</p>
