UITableView load more when scrolling to bottom like Facebook application

ios, iphone, pagination, uitableview

Solution

You can do that by adding a check on where you're at in the `cellForRowAtIndexPath:` method. This method is easy to understand and to implement :

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    // Classic start method
    static NSString *cellIdentifier = @"MyCell";
    MyCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
    if (!cell)
    {
        cell = [[MyCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:MainMenuCellIdentifier];
    }

    MyData *data = [self.dataArray objectAtIndex:indexPath.row];
    // Do your cell customisation
    // cell.titleLabel.text = data.title;

    BOOL lastItemReached = [data isEqual:[[self.dataArray] lastObject]]; 
    if (!lastItemReached && indexPath.row == [self.dataArray count] - 1)
    {
        [self launchReload];
    }
}

EDIT : added a check on last item to prevent recursion calls. You'll have to implement the method defining whether the last item has been reached or not.

EDIT2 : explained lastItemReached

Problem

I am developing an application that uses SQLite. I want to show a list of users (UITableView) using a paginating mechanism. Could any one please tell me how to load more data in my list when the user scrolls to the end of the list (like on home page on Facebook application)?
