从最后一个单元格启动UITableView

Question

I want to show the last cell first in a tableview like whatsapp did. I don't want a scrolling animation. Can anyone help me? Thanks

Answer 1

[tableView scrollToRowAtIndexPath:indexPath atScrollPosition:UITableViewScrollPositionBottom animated:NO];

请注意：动画不是

Answer 2

You can do that by transforming the UITableView and any views you use in it, including UITableViewCell.

First invert the tableview by setting the transform,

tableView.transform = CGAffineTransformMake(1, 0, 0, -1, 0, 0);

then in cellForRowAtIndexPath, you need to set the same transform to cell

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {

     //This is important, since we are inverting the tableview , all subview must be inverted as well
    cell.transform = chatTableView.transform

    return cell
}

but this way you can load cells in recent first order, make sure all subviews is using the same transform as the tableView
