Question

First, why: I have a class called AKTableViewController that inherits from UITableViewController and most of my View Controllers inherit from that.

I’m tryingto make a Category to add a banner on the bottom of each screen, not scrolling with the content, so I add my banner as the self.tableView.tableFooterView and than I position it on scrollViewDidScroll:.

My problem is, when the data is reloaded the banner is sent back to the right position and I don’t have any callback to properly position it.

So: How to be notified when an UITableViewController has reloaded its data?

Answer 1

Use the delegate method for UITableView:

-(void) tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath
{
    if([indexPath row] == ((NSIndexPath*)[[tableView indexPathsForVisibleRows] lastObject]).row){
        //Finished loading visible part of your table
    }
}
