title: Multiple views in iOS ScrollView
body: <p>I'm creating an iOS application, which in one of its screens, I'm using a scroll view, 
  I've two view in that screen to be scrolled "black and red" views,</p>
  
  <p>But, Unfortunately, when i add them to the scroll view only on of them is displayed.</p>
  
  <p>The Frame of both "red and black" views are 320 W * 460 H;</p>
  
  <p>This is my code "I've only the black view displayed": </p>
  
  <pre><code>-(void)viewDidLoad {
  [super viewDidLoad];
  
  scrollView = [[UIScrollView alloc] initWithFrame:self.view.bounds];
  [scrollView setContentSize:CGSizeMake(300, 1200)];
  
  [scrollView addSubview:redView];
  [scrollView addSubview:blackView];
  [self.view addSubview:scrollView];
  
  [scrollView setBackgroundColor:[UIColor lightGrayColor]];
  [scrollView setCanCancelContentTouches:NO];
  scrollView.indicatorStyle = UIScrollViewIndicatorStyleWhite;
  scrollView.clipsToBounds = YES; // default is NO, we want to restrict drawing within   
  //our scrollview
  scrollView.scrollEnabled = YES;
  scrollView.pagingEnabled=YES;
  }
  </code></pre>
