title: Buttons in ScrollView not enabled
body: <p>Using Erica Sadun's scroll view example I created a project.
  I now have a scroll view and a page control in my project.
  I create a new view for each page and add it to my scroll view as seen below.
  Each view has 5 buttons so I can scroll 5 by 5.
  However the buttons do not seem to be enabled.
  Any ideas why?</p>
  
  <pre><code>    // Create the scroll view and set its content size and delegate
      sv = [[[UIScrollView alloc] initWithFrame:CGRectMake(0.0f, 200.0f, 300.0f, 60.0f)] autorelease];
      sv.contentSize = CGSizeMake(NPAGES * 300.0f, sv.frame.size.height);
      sv.pagingEnabled = YES;
      sv.delegate = self;
  
  
      // Load in all the pages
      for (int i = 0; i &lt; NPAGES; i++)
      {
          UIView *menuView = [[UIView alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 300.0f, 60.0f)];
  
  
      for (int j = 0; j &lt; 5 * (i+1); j++)
          {
              UIImage *menuImage = [UIImage imageNamed:@"menuimage.png"];
              UIImage *menuImage2 = [UIImage imageNamed:@"menuimageselected.png"];
  UIButton *menuButton = [[UIButton buttonWithType:UIButtonTypeCustom] retain];
  
              menuButton.frame = CGRectMake(j * 60.0f, 0.0f, 60.0f, 60.0f);
              [menuButton addTarget:self action:@selector(menuButtonClicked) forControlEvents:UIControlEventTouchUpInside];
  
  
          menuButton.tag = j + 5 * i;
  
              menuButton.backgroundColor = [UIColor clearColor];
              [menuButton setImage:menuImage forState:UIControlStateNormal];
              [menuButton setImage:menuImage2 forState:UIControlStateSelected];
              [menuButton setImage:menuImage2 forState:UIControlStateHighlighted];
              [menuButton setEnabled:YES];
  
  
              [menuImage release];
              [menuButton release];
              [menuView addSubview:menuButton];
  
          }
  
          [sv addSubview:menuView];
          [sv bringSubviewToFront:menuView];
  
          [menuView release];
  
      }
  
      [self.view addSubview:sv];
