title: UIView in tableFooterView property doesn't fit inside UITabelView's scrollview
body: <p>I set the tableFooterView of my tableView like this: </p>
  
  <pre><code>UIView *footerView = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 320, 44)];
  UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
  [button setFrame:CGRectMake(10, 10, footerView.bounds.size.width - 20, 44)];
  [button setBackgroundImage:[UIImage imageNamed:@"addItemButton.png"] forState:UIControlStateNormal];
  [button addTarget:self action:@selector(add) forControlEvents:UIControlEventTouchUpInside];
  [footerView addSubview:button];
  self.tableView.tableFooterView = footerView;
  </code></pre>
  
  <p>However, when I scroll to the very bottom of my tableview, my button is cut off. </p>
  
  <p>How can I make sure that the entire button is shown? </p>
