title: Why is UIScrollView not bouncing?
body: <p>I do this:</p>
  
  <pre><code>    scrollView = [[UIScrollView alloc] initWithFrame:self.bounds];
      [self addSubview:scrollView];
  
      NSInteger x = scrollView.bounds.origin.x + Padding, y = scrollView.bounds.origin.y + Padding;
  
      backButton = [[AButtonControl alloc] initWithCaption:@"Back" style:AButtonViewStyleGreen];
      backButton.frame = CGRectMake(x, y, backButton.frame.size.width, backButton.frame.size.height);
      y += backButton.frame.size.height + Spacing;
      [scrollView addSubview:backButton];
  
      ownerNameTextField = [[AFormTextField alloc] initWithFrame:CGRectMake(x, y, 200, 60) label:@"Guest name"];
      y += ownerNameTextField.frame.size.height + Spacing;
      [scrollView addSubview:ownerNameTextField];
  
      guestListSelectField = [[AFormSelectField alloc] initWithFrame:CGRectMake(x, y, 200, 60) label:@"Guest list"];
      y += guestListSelectField.frame.size.height + Spacing;
      [scrollView addSubview:guestListSelectField];
  
      referenceUserSelectField = [[AFormSelectField alloc] initWithFrame:CGRectMake(x, y, 200, 60) label:@"Reference user"];
      y += referenceUserSelectField.frame.size.height;
  
      [scrollView addSubview:referenceUserSelectField];
  
      scrollView.contentSize = CGSizeMake(self.bounds.size.width, y + Padding);
  </code></pre>
  
  <p>And it scrolls fine, but the view does not bounce like it is supposed(?) to.</p>
  
  <p>Any ideas?</p>
