title: iphone: uiscrollview doesn't scroll? but contentsize is set..?
body: <p>hey people,
  I have some data and want to show this in a new view inside a navigation-stack.</p>
  
  <p>I created some new viewcontroller class with XIB file. Then I edited the XIB file and placed the following hierachy:</p>
  
  <pre><code>1 files owner
  2 first responder
  3 scrollview
  3.1 view
  3.1.1 label1
  3.1.2 label2
  3.1.3 label3
  3.1.4 image4
  </code></pre>
  
  <p>I arranged the labels and the image. the content of the labels may differ and they should size dynamically. I also did the IBOutlets in the viewcontroller class and connected everything correctly. the files owner's view delegate is set to view..</p>
  
  <p>then I load the viewcontroller and I do in the "viewDidLoad" - method the following:</p>
  
  <pre><code>- (void)viewDidLoad {
  [super viewDidLoad];
  
  self.currentPageURL.text = [self.offerItem objectForKey: @"page-url"];
  self.currentPrice.text = [self.offerItem objectForKey: @"price"];
  self.currentRank.text = [self.offerItem objectForKey: @"rank"];
  self.currentName.text = [self.offerItem objectForKey: @"name"];
  self.currentProducerName.text = [self.offerItem objectForKey: @"producer-name"];
  
  self.currentDescription.text = [self.offerItem objectForKey: @"description"];
  
  self.imageViewForImage.image = [helperClass resizeImage:[self.offerItem objectForKey: @"picture"] forSize:CGSizeMake(280.0, 280.0) ];
  
  [theScrollview setScrollEnabled:YES];
  [theScrollview setContentSize:CGSizeMake(320, 1200)];
  [theScrollview flashScrollIndicators];
  
  [theScrollview addSubview:theView];
  </code></pre>
  
  <p>}</p>
  
  <p>when I start the app in my simulator, everything is shown, but if I try to scroll, nothing happens..</p>
  
  <p>what do I do wrong? </p>
