title: UIRefreshControl - Pull To Refresh in iOS 7
body: <p>I'm trying to get the pull to refresh feature on iOS 7 in my Table View. In my <code>viewDidLoad</code>, I have:</p>
  
  <pre><code>refreshControl = [[UIRefreshControl alloc] init];
  [self.mytableView setContentOffset:CGPointMake(0, refreshControl.frame.size.height) animated:YES];
  [refreshControl beginRefreshing];
  [refreshControl addTarget:self action:@selector(refreshTable) forControlEvents:UIControlEventValueChanged];
  </code></pre>
  
  <p>I then run:</p>
  
  <pre><code>-(void)refreshTable {
      [self.mytableView reloadData];
      [refreshControl endRefreshing];
  }
  </code></pre>
  
  <p>On iOS 6, this would mean that as you pull down on the table view, it would show the circular arrow that would get stretched out as you pull, and after pulled far enough, it would refresh. Right now, I see no circular arrow. What am I missing?</p>
