title: ios UITableView reloads data when scroll down to bottom rows
body: <p>I've implemented a pull down to refresh that sits above my UITableView. </p>
  
  <p>However, UITableView also has a default setting where if you push up (to reveal rows at the bottom of the table), it also reloads the table data. Since I already have pull down to refresh, I want to disable this. How do I do that?</p>
  
  <p>Thanks!</p>
  
  <p>EDIT: I want to load all the rows of the UITableView at once, not just the visible rows, because I'm not loading too many rows anyway.</p>
