title: UITableView scrollView delegate not called
body: <p>I have a tableview set inside a UIViewController</p>
  
  <pre><code>@property (strong, nonatomic) IBOutlet UITableView *tableView;
  </code></pre>
  
  <p>with delegates set in viewDidLoad</p>
  
  <pre><code>self.tableView.delegate = self;
  self.tableView.dataSource = self;
  </code></pre>
  
  <p>The following methods never get called:</p>
  
  <pre><code>- (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView;
  - (void)scrollViewDidScroll:(UIScrollView *)scrollView;
  </code></pre>
  
  <p>Isn't tableviewdelegate supposed to conform to uiscrollviewdelegate as well?
  Any idea why these methods are never called?</p>
