title: iPhone SDK: UIScrollView does not scroll
body: <p>I just can't get my scroll view to actually scroll.. Everything displays fine except it just won't scroll..... Here's my code:</p>
  
  <pre><code>- (void)viewDidLoad {
      [super viewDidLoad];
  
      UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, 320, 600)];
      scrollView.contentSize = CGSizeMake(320, 600);
      scrollView.scrollEnabled = YES;
      scrollView.clipsToBounds = YES;
      [self.view addSubview:scrollView];
  
      planView = [[WorkoutPlanView alloc] initWithImage:[UIImage imageNamed:@"WorkoutTable.png"]];
      planView2 = [[WorkoutPlanView alloc] initWithImage:[UIImage imageNamed:@"WorkoutTable.png"]];
      planView2.frame = CGRectMake(0, 164, 320, 165);
      planView3 = [[WorkoutPlanView alloc] initWithImage:[UIImage imageNamed:@"WorkoutTable.png"]];
      planView3.frame = CGRectMake(0, 328, 320, 165);
      planView4 = [[WorkoutPlanView alloc] initWithImage:[UIImage imageNamed:@"WorkoutTable.png"]];
      planView4.frame = CGRectMake(0, 505, 320, 165);
      [scrollView addSubview:planView];
      [scrollView addSubview:planView2];
      [scrollView addSubview:planView3];
      [scrollView addSubview:planView4];
  }
  </code></pre>
