iPhone Mail app "Load More Messages..."

At the bottom of the tableview (list of emails), there is a button (?) called "Load More Messages...", is that a button created in the tableview cell or a button created as part of the footerview开发者_开发知识库 of the tableview. either way, how could I do the similar thing in my tableview?

Just use a Button in your tableFooterView

self.tableView.tableFooterView = yourButtonView;
self.tableView.tableFooterView.userInteractionEnabled = YES;

You can use a second section for that with just a single cell.
